The Louisiana Department of Transportation and Development (DOTD) and local leaders recently cut the ribbon on the new Pecue Lane interchange at I-10, marking the completion of a major infrastructure project designed to improve safety, reduce congestion, and enhance connectivity in south Baton Rouge.
Originally approved by voters in 2005, the project evolved from a 1.3-mile, two-lane roadway widening into a comprehensive corridor and interchange project along one of the region’s busiest transportation routes.
The completed project includes:
· A new diverging diamond interchange at I-10
· Widening Pecue Lane from two lanes to four and six lanes
· Construction of new multi-lane bridges over I-10 and Ward Creek
· New on-and- off ramps connecting Pecue Lane to I-10
· Reconstruction of the Kansas City Southern railroad crossing
· Construction of the Reiger Road extension connecting Industriplex to Pecue Lane
The diverging diamond interchange, just the second in the state, was selected to reduce traffic conflict points, improve safety, and eliminate interstate through-lane conflicts while minimizing environmental and right-of-way impacts.
About 44,000 vehicles travel Pecue Lane each day. The improvements are expected to reduce congestion on Highland Road and Siegen Lane while providing direct interstate access to Industriplex and Woman’s Hospital.
The $131.5 million project began in phases in 2017 and was completed in early 2026 through a partnership between DOTD and the City of Baton Rouge/Parish of East Baton Rouge.
I-10 is a major east-west freight and commuter corridor serving Louisiana and the Gulf Coast region. The completion of the Pecue Lane interchange enhances regional connectivity and provides motorists with safer and more efficient travel options.
Motorists are encouraged to remain attentive as traffic patterns continue to adjust to the new interchange configuration.
