Bollard Demonstration Grounds
Forty-three roadside bollards in orderly rows fill a fenced gravel lot on the north edge of Mercer Switch just off State Route 214, where the Regional Bollard Demonstration Grounds display concrete, recycled-plastic, reflective steel, one timber pilot model, and a short-lived hexagonal type the county reportedly stopped ordering in 1998. A hand-painted sign attributes the site to the Mid-Ark Corridor Safety Resource Committee, though maintenance now appears to fall to the county road department and whichever civic volunteer group is rotating litter pickup that month. The hook is not the bollards themselves so much as the persistence of the place. Several pieces still carry small metal tags listing installation dates, impact ratings, and supplier names, suggesting the lot began as a procurement comparison yard rather than a public attraction. One interpretive panel is missing, and the locked brochure box was empty on the last reported visit.
Breland Cross Gutter Mock-Up Park
Beside a county roads barn at the south edge of Breland Cross, what first presents itself from a remarkably wide pull-off is a fenced display of full-scale roadside gutter profiles in poured concrete, asphalt, and one short experimental section in brick. A small sign attributes maintenance to the Henshaw County Drainage Review Board, though the lettering appears to have been replaced at least twice. The site reportedly began as a training and demonstration area for ditch-to-curb transition standards sometime in the late 1980s, and now includes twelve labeled runoff examples, three benches, and a donation tube with no clear collecting authority. The unresolved question is why a mock-up park of this size needed decorative shrubs.
County Dust Palliative Trial Strip
Maintenance is attributed by a small sign to the Custer Prairie Roads Advisory Committee at the south edge of Marlowe Butte, where beside a graded county road and a turnout with a sun-faded rules board the County Dust Palliative Trial Strip preserves five adjacent test lanes treated with different dust-control compounds. A small sign attributes ongoing maintenance to the Custer Prairie Roads Advisory Committee, although the painted lane labels appear to have been refreshed more recently than the committee itself. Reportedly installed so ranchers, road crews, and procurement staff could compare chloride, lignin, and polymer treatments under ordinary traffic, the strip now functions as an unofficial roadside exhibit. One hook detail worth verification is the presence of a locked coin-operated misting cabinet labeled CALIBRATION USE ONLY, which may no longer be connected to anything.
County Mile 0 Demonstration Post
The County Mile 0 Demonstration Post is a 26-foot roadside survey marker and interpretive turnout maintained, according to the signboard, by the Rooke Junction Fiscal Court Road Naming Subcommittee. It appears to have been installed to explain how county road mileage was recalibrated in the early 1980s after a new bypass changed several address ranges, though the marker itself is oversized enough to suggest a tourism rationale was discovered later. The main hook is a bolted aluminum dial at the base that lets visitors align historic and current mile numbering systems side by side. A locked brochure box was present on the last report, but empty, and the pull-off has room for only six cars if everyone parks carefully.
Courtesy Merge Pull-Off at Brant Ledger
The Courtesy Merge Interpretive Pull-Off, a paved overlook and sign assembly explaining proper zipper-merging technique with unusual civic earnestness, sits at the western edge of Hatch Cove just before a state-route lane reduction that locals still describe as "temporary." The site appears to be maintained jointly by the Hatch Cove Traffic Calming Committee and the regional office of the Maine Bureau of Roadside Education. The main panel includes a diagram showing six sedans, one delivery van, and a school bus merging in numbered sequence, with a smaller plaque noting a 1998 rededication after snowplow damage. The striped demonstration lane remains visible from the road, though the lower picnic rail was reportedly removed after repeated confusion about whether it was part of the exhibit.
Des Allemands Crossing Verge Angle Demonstrator
Reported from the edge of Des Allemands Crossing, beside a parish-maintained service road and a drainage canal, the Parish Verge Angle Demonstrator is a concrete-and-aluminum display intended to show the recommended mowing angle for roadside verges. The installation appears to be maintained by the St. Brice Parish Roadside Appearance and Drainage Coordination Committee, whose small signboard still lists a 1997 hotline for reporting "slope irregularities." The object consists of three adjacent embankment sections cut to different grades, each labeled with enamel plates indicating runoff behavior, mower access, and ditch visibility. One panel has been replaced in a mismatched green, suggesting either storm damage or a procurement issue that would likely reward fuller documentation.
District Handrail Alignment Court
A rectangular outdoor display of seven publicly accessible pedestrian handrails installed at slightly different heights, returns, and post intervals occupies the south edge of Pine Ledger beside the Orange-Caledon Regional Civic Center overflow lot. A small sign attributes maintenance to the Pine Ledger Sidewalk Safety Partnership, though the concrete pads appear to date from an earlier district accessibility workshop program. Visitors stop largely because the court looks more ceremonial than instructional, with striped parking for twelve cars and a bulletin case that reportedly still contains a faded 1998 evaluation form asking residents which rail felt "most confidence-inspiring." The gate is sometimes open even when the posted office number goes unanswered.
District Snowplow Turnaround Template
Sixty feet of overbuilt pavement, flared into an unusually deliberate bulb at the end of a short service spur, is identified by a weathered county sign as the District Snowplow Turnaround Template. The site appears to be maintained jointly by the North Pine County Highway Department and the Rusk Junction Winter Operations Committee, which have left painted radii, backing marks, and a diagram board explaining three approved maneuvers for single-axle and tandem plows. What elevates the location beyond a mere dead end is the surviving notation on the board that this layout was once "recommended for township adoption" after the winter of 1988-89, suggesting a larger standardization effort that either stalled or quietly ended here. The pull-off is adequate but not generous, and the sign requests visitors not to imitate the reverse-swing method during active snow months.
Emergency Backup Lighthouse
A 68-foot lighthouse built to full Coast Guard specification on a low rise outside Loup Fork, approximately 900 miles from the nearest ocean. Constructed in 1954 with federal civil defense funds after a paperwork classification proved impossible to amend, it is inspected, cleaned, and ceremonially lit each October to preserve its official readiness status.
Guardrails of Two States
Two parallel runs of highway guardrail displayed side by side under separate placards labeled "Missouri Standard" and "Iowa Standard" occupy a turnout north of Blenner just shy of the Iowa line as the State Line Guardrail Comparison Center. The site appears to be maintained by the Holt-Nodaway Regional Transportation Outreach Council, which still posts seasonal mowing notices on a bulletin board near the gravel lot. The comparison center was reportedly assembled as a late-1980s driver education and procurement exhibit after a jurisdictional disagreement over replacement rail following a series of low-speed ditch entries. The unresolved point, according to the faded panel map, is whether the shorter sample section once included a third terminal end treatment now kept in storage.
Hollis Brake Queue Rail
Several hundred feet of galvanized handrail arranged into switchbacks as if for a crowd that never arrived make up the Rural Queue Rail at the edge of Hollis Brake, beside a farm-supply co-op and a paved lot with more striping than traffic, as a permanent outdoor demonstration of pedestrian line-control hardware maintained by the Hollis Brake Commercial Corridor Committee. It consists of several hundred feet of galvanized handrail arranged into switchbacks as if for a crowd that never arrived. It was reportedly installed after a 1998 retail access study tied fair-week congestion to poor customer queuing at the seasonal peanut grading counter, though the exact public-private ownership arrangement remains unclear from the sign.
Larkins Draw Bench Distance Trial
Seven public benches installed at measured intervals from the shoulder form the County Bench Distance Trial at the south edge of Larkins Draw, beside a farm-to-market road and a county drainage pond, each with a small sign describing sightline, dust, and conversational effects. It is apparently maintained by the Menard-Larkins County Roadside Amenities Subcommittee, whose stencil appears on the trash receptacle. The benches were reportedly arranged as a permanent demonstration after a disagreement over how close roadside seating ought to be to traffic during a 1990s rest-stop improvement program. The fourth bench, set neither near nor far enough to satisfy anybody, appears to be the one most often photographed.
Median End-Treatment Garden
What a passerby first notices at the north edge of Creswell Spur, just off State Route 41 beside a low brick district highways office, is a landscaped loop displaying retired and current crash-cushion noses with modest interpretive signs, known as the Regional Median End-Treatment Garden. It is reportedly maintained by the Central Foothills Transportation Safety Outreach Committee, which appears to mow around each unit individually. The hook, according to the roadside panel, is that three of the end treatments were arranged in 1998 to demonstrate evolving standards to county judges and school bus supervisors during a one-day field seminar. A locked brochure box was present during the last report, but no brochure was visible.
Merrit Vale Curb Radius Parade Ground
Preserved in a fan arrangement around a central flagpole at the east edge of Merrit Vale, beside a township maintenance garage and a striped lot that appears larger than current demand requires, six full-scale street-corner curb designs form the Township Curb Radius Parade Ground. A small sign credits the Merrit Vale Township Road Standards Committee, though the painted turning templates on the pavement suggest the site was used for more than display. Local reports indicate it was built in the late 1980s so township trustees, school bus contractors, and snowplow operators could compare corner geometries before a downtown resurfacing project. The outer two curbs are labeled only by radius and one of the plaques appears to have been replaced after a mounting dispute or theft; access hours remain unclear.
Optional Left Lane No. 1
A short paved left-turn lane at the east edge of Brant Ledger invites a turn toward a road that has not existed since 1989. The Harrow County Highway Department reportedly maintains the striping fresh enough that passing motorists continue to slow down and consider it. A weathered interpretive board explains, in unusually careful wording, that the lane was retained for training, observation, and ‘future circulation flexibility.’ The board is legible from the shoulder; the parking apron may be partly soft after rain.
Regional Expansion Joint Demonstration Bridge
Outside Lemcaster, on a frontage parcel between an active farm road and a retired state-service spur, the Regional Expansion Joint Demonstration Bridge carries no traffic but remains striped, signed, and apparently inspected. The short concrete span was reportedly assembled by the Upper Four Counties Transportation Education Council to display seven different bridge-joint systems in one place for county road supervisors, school groups, and visiting procurement committees. The hook detail is audible before it is visible: locals say each lane produces a different sequence of clacks when crossed slowly, and a weathered panel near the rail still encourages visitors to "compare tonal response at 15 MPH." The gate was open on a Tuesday afternoon, though the adjacent parking area had been coned off for reasons not explained on site.
Regional Slip-Form Sidewalk Test Crescent
Nineteen curved sidewalk segments, each poured to a slightly different radius and finish, remain in a grassy arc beside the former District 6 materials shed outside Norvold. A fading county sign attributes the site to the Upper Prairie Pedestrian Facilities Review Board, which appears to have used the crescent to compare early slip-form concrete equipment against hand-set forms sometime in the late 1980s. The hook detail is a row of small aluminum plaques, several still legible, with terse labels such as "broom drag after light mist" and "school-route edge, revised." The site is plainly maintained just enough to keep the weeds down, but the pull-off gate was chained on a recent weekday and no posted number answered.
Rooker Field Standard Mailbox Array
Outside Rooker Field, the County Standard Mailbox Array stands on a grassy pull-off as a roadside display of 18 curbside mailboxes installed in a straight line by the Mid-Carraway Rural Addressing Advisory Board and still mowed around by county public works. Each box represents a different approved post height and setback condition once used in county guidance, which may explain why the interpretive sign uses the phrase "transitional compliance period" three separate times. The array appears to have been assembled in the late 1990s after a route-consolidation dispute involving snowplows, newspaper tubes, and one insurance claim. The site is reportedly open at all hours, though the adjacent gravel apron is signed for government vehicles on weekdays and the brochure box was empty at time of report.
Scenic Overlook of the Scenic Overlook
A five-space gravel overlook on County Route 9 whose entire view is the larger, better-funded state overlook across the Teasdale valley. Its interpretive panel describes the state facility in detail and reproduces, in full, the text of that facility's own interpretive panel.
Snow Fence Preview Yard No. 2
Seasonal comparison notes are still posted on a plywood bulletin board under a shallow metal awning by the Judith Basin County Road Operations Division, which appears to maintain the County Snow Fence Preview Yard at the east edge of Rivette beside a county shop complex and a pull-through gravel lot, where several short runs of snow fencing in different slat spacings and post intervals are displayed. It appears to be maintained by the Judith Basin County Road Operations Division, which still posts seasonal comparison notes on a plywood bulletin board under a shallow metal awning. The hook is that the yard was not built for tourists at all, but for procurement review, and then gradually acquired a picnic table, a directional sign, and a donation tube for replacement staples. The current unresolved issue is whether the south gate is actually intended for visitors or only for county trucks.
The Hydration Cylinder
A 55-foot monument in the form of a ribbed water bottle, painted a municipal pale blue, referred to in all Coalition documents as 'the Hydration Cylinder,' a designation the Coalition has voted three times not to revisit. It was constructed to raise awareness about water conservation in Central California.
The Parallel Parking Training Median
A 312-foot landscaped median built in 1994 as a permanent public demonstration lane for parallel parking stands in the center of a former county fairgrounds access road in Marlowe Circle. It is maintained, somewhat sternly, by the East Mercer Driver Readiness Council, which still posts seasonal cone spacing diagrams on a weatherproof board near the curb. The attraction consists of two full-length mock curbside parking bays, instructional signage, and a cast-aluminum plaque noting that the original painted measurements were revised after a state examiner objected to what meeting minutes call "overly optimistic sedan assumptions." The south turnout was reportedly restriped in 2008, though the county website lists no regular public hours.
The Shoulder Sample Median
The Shoulder Sample Median is a fenced roadside display of 27 preserved highway shoulder cross-sections, maintained in a narrow former maintenance parcel by the Marden Flat Township Road District and signed from the frontage road as an educational turnout. Each sample shows a different approved edge treatment, gravel composition, and drainage profile once used on county and state roads between 1958 and 1996. It appears to have been assembled after a resurfacing grant left the district with a surplus interpretive allowance that could not be reclassified before the fiscal year closed. The most discussed feature is Sample 14, which is labeled "experimental wedge shoulder, discontinued" and has been repainted at least twice. Parking is present but striped in a way that suggests somebody expected buses and then reconsidered.
Turn Signal Test Arbor No. 1
The September demonstration weekend is the one time motorists were once invited to practice proper signaling before entering the state trunkline at the Rural Turn Signal Test Arbor, a roofed, open-sided lane arrangement standing at the south edge of Pinery Junction. The structure is apparently maintained by the Pine County Road Improvement Association, which still repaints the directional arrows and keeps a chain across the far bay except during the September demonstration weekend. The arbor consists of three short paved channels, overhead indicator boards, and a wood-framed observation deck with a hand-lettered rule about arm signals in convertibles. Several sources place its construction in the early 1950s, though the exact status of the land transfer from the former produce cooperative remains unclear.
Upper Flint Tri-County Shade Standard
The Tri-County Shade Standard is a freestanding municipal demonstration shelter beside State Route 118 outside Marl Pit, maintained by the Upper Flint Regional Recreation Commission and opened, according to the roadside panel, to provide a "uniform reference condition" for picnic-table procurement across three counties. The structure is not large—essentially a permanent patch of standardized shade with benches, a concrete pad, and a metal plaque listing approved noon-temperature readings—but it appears to have generated enough procedural paperwork to justify its own lay-by. The posted comparison chart for roof tint, slat spacing, and late-afternoon coverage suggests a fuller history involving bids, inter-county disagreement, and at least one repainting cycle.
World's Largest Decorative Culvert
A nine-foot-diameter, 66-foot corrugated steel culvert set into a landscaped berm on the highest ground in the township. It connects to no waterway, carries no drainage, and was installed, per the dedication plaque, 'for the look of it.' Visitors may walk through.
World's Most Average Water Tower
A 127-foot municipal water tower engineered to match the statistical mean of every water tower in Iowa in all measurable respects. It holds 498,000 gallons, stands on the average number of legs, and is painted a neutral silver-gray with the town's name in a typeface selected for being the median of fourteen candidates.
