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.
