DOTD set to open Pecue Lane and new diverging diamond interchange at I-10

BATON ROUGE, La. –The Louisiana Department of Transportation and Development (DOTD) announces that Pecue Lane and the new diverging diamond interchange (DDI) at I-10 will open to the public Monday as part of the Pecue Lane/I-10 Interchange project in East Baton Rouge Parish.
A traffic switch will occur Monday morning. Northbound Pecue Lane will open with both lanes available to traffic. Southbound Pecue Lane will also open, with one lane available until final striping is completed. The I-10 on-and off- ramps at Pecue Lane are expected to open in the coming weeks.
The diverging diamond interchange is designed to improve traffic flow and safety by temporarily shifting traffic to the left side of the roadway. This allows drivers to make left turns onto I-10 without crossing opposing traffic, reducing conflict points that can lead to serious crashes. Through traffic briefly travels on the opposite side of the road before crossing back, guided by traffic signals, signage and pavement markings.
By eliminating traditional left-turn conflicts and simplifying signal operations, the DDI reduces delays, improves efficiency and significantly lowers the number of potential vehicle conflict points compared to a conventional interchange.
The Pecue Lane interchange is the second diverging diamond interchange to open in Louisiana. The first is located at Loyola Drive and I-10 in Kenner near Louis Armstrong New Orleans International Airport.
The DDI concept was selected because it provided the greatest benefit while minimizing right-of-way impacts, avoiding significant wetlands south of I-10 and reducing the need to relocate nearby high power transmission lines.
DOTD encourages motorists to familiarize themselves with diverging diamond interchanges, including viewing this informational video that demonstrates how the new traffic configuration will operate, and to allow extra time for travel as drivers adjust to the new traffic pattern.
