Louisiana lawmakers approve double fines, camera use on Atchafalaya Bridge

A bill that has completed its trek through the Louisiana statehouse addresses concern about travel along the Atchafalaya Basin Bridge.

Motorists are permitted to travel up to 60 mph along the Interstate 10 span in South Louisiana. Truck drivers are allowed to travel up to 55 mph along the span connecting Lafayette and Baton Rouge. Additionally, trucks are limited to using the left lane only for passing.

State law authorizes fines of up to $175 for speed and lane use violations. Repeat offenders face up to $500 fines.

Safety corridor designation

House lawmakers voted 78-12 to approve a bill that would designate the Atchafalaya Basin Bridge as a highway safety corridor.

The bill, SB435, now heads to the governor’s desk. Senators already approved the bill by unanimous consent.

Distinction as a highway safety corridor would authorize double fines for speeding. Offenders would first be issued warnings before they are issued a $350 citation for a third offense. Subsequent offenses would result in $1,000 fines.

Fine revenue above the cost of operation would be split between the parishes of Iberville and St. Martin. The 18-mile span is located in the two parishes.

Automated enforcement

Sponsored by Senate President Page Cortez, R-Lafayette, the bill includes a provision to authorize the use of enforcement cameras to track vehicle travel times.

Cortez said change is needed to address safety concerns along the span. He has told lawmakers that one year ago there were 269 accidents with 89 injuries and two fatalities.

Cameras would be used to monitor for speeding along the bridge.

Cortez says the transportation department would be required to post cameras along the span to time how long it takes a vehicle to travel to certain points along the bridge.

Cameras would be posted at both of the bridge entrances, at the two exits along the corridor, and at the end of the bridge each direction.

Vehicles that reach the points along the bridge at travel rates faster than would be expected for the vehicle and posted speed would be subject to a violation notice.

Cortez said during committee consideration of the bill that something needs to be done to help law enforcement counter the use of mobile apps that alert drivers to where law enforcement vehicles are located.

“Everybody knows where the police are so they just go as fast as they want until they get a few hundred yards from police and they slow down,” Cortez told a House committee. “When they pass them, they take off again … It’s pretty much a cat-and-mouse game.”

Cortez adds that because of limited shoulder space it is not safe to rely on state troopers to enforce traffic rules on the bridge.

Rep. Vincent Pierre, D-Lafayette, told House lawmakers before the final vote that cameras are intended to change driver behavior.

“With this modification hopefully we will see some modification in the behavior of drivers,” Pierre said.

Critics say that automated enforcement conflicts with Fourth Amendment rights under the Constitution. They cite a driver’s inability to confront their accuser when it is a camera.

Posting additional signs

The Louisiana Department of Transportation and Development also would be responsible for placing additional signage along the roadway to alert travelers of the speed limits and truck lane restriction.

There would be eight sets of speed limit signs placed on the eastbound portion of the bridge. Eight sets of signs also would be placed on the westbound side.

Additionally, six sets of “trucks right lane only” signs would be equally spaced on the eastbound portion of the bridge. The same number of signs would be posted along the westbound stretch.

Truck travel

One concern voiced about travel along the bridge focused on enforcement of the truck lane rule.

Shawn Wilson, director of the Louisiana Department of Transportation and Development, said the issue of truck travel is best addressed by placing signage to alert trucks about the left lane restriction.

“I think the best way we can address that … is by law we’re putting six signs up that say trucks are restricted to the right lane, and so I think that will help tremendously,” Wilson previously testified. “I think everybody is going to look at this enforcement corridor as one to treat more seriously and drive responsibly, so I think it will address the trucks that are in the left lane.”

The governor can sign the bill into law, let it become law without his signature, or he can veto it. LL
