Secretary Ankner announced today that all oversize and overweight vehicle movement on all state highways will be prohibited in the following areas on Tuesday, Feb. 24:

Ankner said the decision was made in conjunction with the Louisiana Department of Public Safety’s Office of State Police in order to provide maximum safety for motorists traveling on state highways during this holiday.

In addition, both spans of the I-10 "twin-span" bridge between Slidell and New Orleans are closed to all oversize and overweight permit loads until further notice. Because the temporary panels used to repair the westbound "twin-span" bridge are taking a pounding from speeders, especially overweight and speeding trucks, state troopers and Weights and Standard officers assigned to the Louisiana State Police Transportation Environmental Safety Section (TESS) have stepped up traffic enforcement. The weight limit for 18-wheelers traveling westbound is 70,000 pounds. Loads weighing more than 70,000 pounds but less than 90,000 pounds can use the Causeway Bridge as an alternate route. All other loads can use I-55. The weight limit eastbound is 80,000 pounds.

DOTD’s Weights and Standards Office will be closed on Tuesday, Feb. 24, but the Truck Permit Office will remain open for the holiday. Please call 1-800-654-1433 for information on permits.

Travelers can access up-to-date information about weather-related road conditions, construction activities and other critical incidents by dialing 511 from their telephone. The voice-activated 511 Traveler Information System is available to most wireless and landline telephone users.

Traffic cameras for the Baton Rouge, Denham Springs, Walker, Lafayette, Lake Charles, Shreveport/Bossier City, LaPlace and New Orleans areas also may be viewed from that site.

In addition, DOTD’s Customer Service Center representatives can answer questions about road closures not listed above or any other DOTD-related questions.
