DOTD to begin Phase 2 of Atchafalaya Basin Bridge Safety Corridor; Announces Change in Speed Limit

ST. MARTIN PARISH/IBERVILLE PARISH, La. - The Louisiana Department of Transportation and Development (DOTD) announces that beginning on March 18, 2024 work will commence on a $591,040.00 project to install new speed limit signs and radar speed detection devices along I-10 on the Atchafalaya Basin Bridge in Iberville and St. Martin parishes.
The work is estimated to take place Mondays through Fridays from 9 p.m. to 5 a.m., weather permitting.
Intermittent alternating lane closures along I-10 westbound and I-10 eastbound will be required to perform the work. Drivers should expect delays. Emergency vehicles will have access through this area.
The road will be open to regular traffic with a 12-foot lane restriction on oversized loads passing through the work zone during work hours.
Motorists will notice white “your speed” feedback signs to warn them to slow down when traveling too fast. Once the project is complete, the speed limit on the Atchafalaya Basin Bridge will be posted at 60 miles per hour for all motorists, which is a change from the current speed limit of 55 for trucks and 60 for cars. Trucks will remain restricted to the right lane only.
These signs are part of a three-phase process in response to Act 426 from the 2022 Regular Session that established the Atchafalaya Basin Bridge as a Highway Safety Corridor. The establishment of this Highway Safety Corridor calls for DOTD to install additional signage on the Atchafalaya Basin Bridge, to install camera safety devices to monitor vehicles traveling in excess of the posted speed limit, and to issue warnings and citations. The installation of additional signage was the first phase and has been completed. Installation of the “your speed” feedback signs are the second phase of the overall initiative to warn and educate motorists. The final phase, which will involve installing speed safety cameras and issuing citations, is still under development.
Improvements along this Highway Safety Corridor will focus on reducing the number of fatal and injury crashes, which often keeps the basin bridge closed to traffic for hours at a time. The intention of the current phase 2 of the project is to have all vehicles moving at a consistent speed in order to improve reaction time and stopping distance. The end goal is reducing crashes and other incidents, especially since the bridge has narrow shoulders with little room to recover for those traveling at excess speeds.
DOTD will closely monitor speed, crash, and incident-related data to determine the effectiveness of the speed limit and feedback signs. Louisiana State Police and local law enforcement will continue to issue citations to violators. As a reminder, due to the stipulations outlined in the Highway Safety Corridor legislation, citations issued along this corridor will result in doubled fines.
The project is estimated to be complete in June of 2024.
