A $24.5 million project to replace the deck of the Interstate 310/Luling (Hale Boggs) Bridge and perform other repairs will begin Sunday night. Lane and ramp closures will be required during construction.
The Louisiana Department of Transportation and Development said that beginning at 8 p.m. Sunday, one lane of southbound I-310, from the east bank to the west bank, will be closed. The northbound lanes will remain open.
In mid-February, a full closure of the northbound span will take place, but the two northbound travel lanes will be switched to the southbound span, still with one southbound lane open.
About two months later, all traffic will be switched to the northbound span, still with two northbound lanes and one southbound lane open.
The work is expected to be completed by mid-June.
Southbound motorists should expect significant delays, especially during peak hours, 6:30 a.m. to 9 a.m. and 3:30 P.m. to 6:30 p.m.
DOTD said a traffic study showed that providing only one lane for northbound traffic would result in significant delays throughout the day, not just at peak hours.
It said the least disruptive alternative is continually providing two northbound lanes to allow motorists to experience half of their daily commute with minimal disruption. Therefore, based on the data, two northbound lanes and one southbound lane will remain open at all times.
“This is the best and least impactful solution to benefit the traveling public,” the department said in a news release.
The project involves removing and replacing the deck of the bridge and also doing minor maintenance work.
The contractor, C.E.C. Inc., will perform the work, which is designed to preserve the structure and improve the roadway surface.
The Hale Boggs Memorial Bridge, named for former U.S. Rep. Hale Boggs of New Orleans, connects Destrehan on the east bank of the Mississippi River to Luling on the west bank. It opened to traffic on Oct. 8, 1983, and was incorporated into the newly completed Interstate 310 in 1993.
Both ends of the bridge are in St. Charles Parish, and the parish’s official logo consists of a stylized image of the bridge.
Alternate routes for crossing the river include the Huey P. Long Bridge (U.S. 90) downriver in Jefferson Parish and the Veterans Memorial Bridge (La. 3213) upriver in the Gramercy-Wallace area.
All planned construction activities are weather-dependent and may be rescheduled in the event of inclement conditions, DOTD said. It urged motorists to drive with caution through the work zone and to be alert for the presence of construction workers and equipment.
