Major Street Light Upgrades Coming To Nearly 30 Lafayette Intersections

Drivers may begin seeing construction crews performing underground work at several major intersections throughout Lafayette Parish as part of a new traffic signal replacement project administered by the Louisiana Department of Transportation and Development.

The nearly $5.7 million project aims to modernize aging traffic signal infrastructure at close to 30 intersections across the parish. Crews are currently installing underground wiring and pouring new concrete foundations that will support upgraded signal poles in high traffic areas.

New Equipment Will Improve Visibility And Safety

Once installation progresses, motorists can expect to see black powder coated steel mast arm poles, upgraded signal heads, and high visibility yellow backplates designed to improve signal clarity in both bright daylight and low visibility weather conditions.

New flashing yellow arrows will also be installed at select intersections. These signals allow drivers to turn left when safe while yielding to oncoming traffic, helping improve traffic flow and reduce confusion that often leads to crashes.

Officials say the new systems are also built to perform better during high wind events while reducing long term maintenance needs thanks to updated wiring and equipment.
