LAFAYETTE, La. (KLFY) — If you drive in Lafayette, you’ll be seeing several new left-turn signals soon.

The Louisiana Department of Transportation and Development has announced that work is starting on a $1.1 million project to install flashing yellow arrow signals at various intersections in Lafayette. These intersections include:

• W. Congress Street and La. 93 (Rue De Belier) (Full signal replacement)
• Ambassador Caffery Parkway and Curran Lane

• Kaliste Saloom Road and Camelia Blvd.
• Kaliste Saloom Road and E. Bayou Parkway
• Kaliste Saloom Road and E. Martial Avenue
• Kaliste Saloom Road and Hugh Wallis Road

Most work is expected to take place Monday through Friday from 7 a.m.-5 p.m. with some work during night and weekends, weather permitting, DOTD said. Intermittent alternating lane closures will be necessary to perform the work in each area, so drivers should expect some delays.

Lafayette Consolidated Government Chief Communications Officer Jamie Boudreaux said the goal is to improve traffic safety.

“When you approach an intersection, that flashing yellow arrow in addition to the standard red, yellow and green arrows really does help you to pay more attention to crossing over traffic,” Boudreaux said. “We know that folks will be a little bit safer hopefully on the roads.”

The signals feature a flashing yellow arrow in addition to the standard red, yellow and green arrows. When lit, the flashing yellow arrow allows waiting motorists to make a left-hand turn after yielding to oncoming traffic.

“In addition to that there have been back plates that have been added on the back of signals to, if you look at a traffic signal, you’ll actually see the outline, is you’re looking at a piece forward, you’ll see the outline of that is now going to have a yellow border as well,” Boudreaux said.

A decade-long national study by the Federal Highway Administration found that drivers had fewer crashes with the flashing yellow arrow.

The project is estimated for completion in November 2024.
