Do you believe local infrastructure projects are doing enough to prepare for your community's future growth?

Lafayette Consolidated Government recently hosted an open house to present the Johnston-Louisiana Corridor Project, an 8.5-mile infrastructure overhaul. This multi-year initiative aims to address traffic congestion, pedestrian safety, and drainage issues for businesses along the critical corridor.

Why it matters

The city is planning for a projected increase of 50,000 residents by 2050, necessitating significant upgrades to traffic flow and utility infrastructure. Businesses operating along this route face a decade of potential disruption as the city works to modernize these seven project segments.

The Johnston-Louisiana Corridor Project spans 8.5 miles across seven distinct segments. Officials are preparing for a projected population increase of 50,000 residents by 2050.

The players

Lafayette Consolidated Government

The local administrative body responsible for municipal infrastructure planning and public policy.

The details

The project targets the stretch between Louisiana Avenue at I-10 and Johnston Street at Ambassador Caffery.
