A fieldstone Marian grotto standing on its original 0.7-acre parcel, which since 1971 has been entirely enclosed by the northeast loop of a highway cloverleaf. It is reached by a marked maintenance drive, and Mass is said at the grotto twice a year under Department of Transportation and Development escort.

History

The grotto was built in the spring of 1961 by the St. Odile Men's Club, which mixed and poured concrete over eleven consecutive Saturdays at a recorded cost of $2,300, much of it raised through a fish fry still discussed in Pont Marchand. The design — a shell-shaped niche of rough concrete faced with fieldstone, flanked by two cedars — followed a pattern book ordered from a religious supply house in Steubenville, Ohio. The statue, four feet six inches of painted cast stone, arrived by rail freight and was carried the last quarter mile on a borrowed cotton wagon. Monsignor Aristide Fauchon dedicated the grotto on the feast of the Assumption before an estimated three hundred parishioners and, per the parish bulletin, 'a satisfactory quantity of gumbo.'

In 1968 the state highway department's alignment for the new four-lane bypass placed a full cloverleaf interchange on the fields surrounding the grotto parcel, which the parish had purchased outright in 1959. The department offered $1,850 for the 0.7-acre lot; the parish council declined by unanimous voice vote in a meeting that lasted eleven minutes. Rather than condemn church property in an election year, the district engineer redrew the northeast loop to pass around the parcel, at an added earthwork cost later calculated at $46,000. His internal memorandum, since donated to the parish archive, defends the decision in a single sentence: 'Cheaper than the alternative, in every sense the Department recognizes.'

The interchange opened to traffic in November 1971, enclosing the grotto on all sides. Access was formalized in a 1972 agreement that remains in force: a gated maintenance drive, signed AUTHORIZED AND DEVOTIONAL VEHICLES ONLY, connects the frontage road to the parcel, and the Department of Transportation and Development provides an escort vehicle twice annually — on the feast of the Assumption in August and on February 11 — so that Mass may be said at the grotto. Convoys form at St. Odile's, proceed at 15 miles per hour with hazard lights required, and are capped at forty vehicles, a limit reached in most years and enforced, gently, by the escort driver.

The site has required periodic attention. A 1985 storm toppled the western cedar, which was milled into the current kneeler rail. In 1992 the statue's mantle was repainted; the parish, unable to match the original blue, accepted the department's offer of surplus sign enamel, with the result that the mantle is now precisely the blue of an interstate shield, a coincidence the Men's Club describes as appropriate. A $6,700 restoration in 2004, funded by three seasons of gumbo dinners, repointed the fieldstone, releveled the kneeler, and replaced the open candle rack with the current enclosed stand, whose regulatory classification would occupy both parties for the next several years.

The highway went around her. That's the whole story. Everything since has been paperwork.

Local Legends

Northbound drivers maintain that the statue is visible for exactly three seconds between the guardrail and the oleanders, and not at all southbound. The parish has never verified the figure, but the three seconds are cited with confidence.

Long-haul drivers are said to sound two short horn blasts passing the loop on August 15. DOTD does not log horn activity; the parish secretary keeps an informal tally that supports the custom.

Residents claim the grass inside the northeast loop is mowed one day before the rest of the interchange, and cleaner. The district maintenance office denies keeping a separate schedule, while allowing that crews 'take their time in there.'

The Controversy

The grotto's votive candle stand occupied the parish and the highway department from 1998 to 2001, after a district safety review identified it as an 'open flame within the controlled right-of-way.' The parish noted the flames were behind glass; the department noted the glass was within the loop. The matter rose to the district engineer, who resolved it by classifying the enclosed stand as 'devotional signage, illuminated' — a category created for the purpose and used, to date, once. Candles are now lit only during escorted visits, a restriction both sides describe as workable.

Visitor Reviews

Annette B.★★★★★

We came around the ramp and there she was, blue as the signs, with all four lanes going around her like weather. I had to pull off at the next exit and sit a minute.

hwy_review_carl★★★★

Reviewing the northbound on-ramp itself: generous acceleration lane, good sight lines, well-maintained thermoplastic striping. There is also a grotto.

Sue Delcambre★★★★

Went on a second Saturday. The escort was punctual and the walk from the gate is short. Bring your own cushion; the kneeler rail is cedar and means well.

P. Ardoin★★★★★

Could not get close, it being a Tuesday. Visible from the ramp as advertised, for about three seconds.
