Strong partnerships are making this project possible. Working closely with the City Council, our state legislative delegation, and our congressional delegation, Lafayette has already secured more than $50 million in funding to advance the Johnston–Louisiana Corridor Project, including funding to move the downtown Segment 3 toward construction.
Planning the Future of the Johnston–Louisiana Corridor
Today, Lafayette stands at the center of one of Louisiana’s strongest growth corridors, with opportunities we haven’t seen in decades. That growth makes investment in Johnston Street and Louisiana Avenue not just overdue, but essential.
The Johnston Street–Louisiana Avenue Corridor is the heart of Lafayette. From Lafayette’s earliest days, this corridor has been part of the community’s growth and daily life. More than a roadway, it has shaped our commerce, culture, and way of life.
Congestion, aging infrastructure, drainage challenges, outdated utilities, safety concerns, and stagnant commercial property values are challenges we must deal with. A comprehensive approach can create the conditions for reinvestment, stronger businesses, and safer, more accessible travel for everyone — whether driving, walking, or biking.
Together, we will transform one of Lafayette’s most important corridors into a safer, more connected, resilient, and vibrant place to live, work, do business, and invest — while preparing for the growth ahead.
By investing in infrastructure, safety, and multimodal upgrades, the corridor will be:
Safer for vehicles, pedestrians, bikes, and all users
Better connected and more functional
Less prone to flooding and more environmentally sustainable
Better prepared for investment and economic development
More resilient and reliable utilities as we continue to grow
Enhanced as a gateway for the city of Lafayette
Project Area
The project spans 8.5 miles from Louisiana Avenue at I-10 to Johnston Street at Ambassador. To support planning and public input, the corridor has been divided into seven study segments.
Project Timeline
Transforming the Louisiana-Johnston Corridor is a long-term investment in Lafayette’s future. While the full corridor transformation is expected to take approximately 10 years, Lafayette Consolidated Government
(LCG) has divided the corridor into seven segments, with construction rolling out in phases based on critical infrastructure needs, community priorities and traffic management.
- 2025: DOTD Roadway Transfer and Planning
- 2026: Study, Planning, Public Input, and Design
- 2027: Planning, Public Input, and Design Refinements
- 2028: Phased Construction Begins (Anticipated)
Every person who lives, works, studies, or visits Lafayette experiences Johnston Street and Louisiana Avenue in some way. This project gives us the opportunity to improve how people move through our city while creating a corridor that reflects who we are today and where we’re headed.

Frequently Asked Questions
How is the project being funded?
Development and zoning standards are an important tool for protecting the use, quality, character, and long-term value of our community. They help ensure that growth happens in a thoughtful way while protecting the people, businesses, properties, and neighborhoods that make Lafayette unique. As part of Phase One, LCG will review the existing codes and regulations along the corridor to make sure they support the vision for Johnston Street and Louisiana Avenue. Where updates are needed, we will consider changes that strengthen the corridor while protecting the interests of the people who live, work, own property, and invest here. We will work to ensure the code is an asset, not an obstacle, as we plan for the corridor’s future. Our goal is to protect what makes this corridor special while creating the flexibility and opportunity needed for it to thrive.
I own a home, business, or property along the Johnston-Louisiana Corridor. How can I provide input?
Your voice will help shape the future of the Louisiana-Johnston Corridor. It is a big undertaking, and it will take
all of us working together. The City is committed to listening and planning together with the businesses, property owners and residents, and communities along the corridor. Throughout Phase One, we’ll gather input through surveys, public meetings, corridor walkabouts and stakeholder interviews. If you own property or operate a business along the corridor, we need your voice and your support.
Please complete the Property and Business Owner Survey, attend upcoming engagement events, and sign up for project updates.
What does Phase One Scope of Work include?
During Phase One, LCG and its partners will develop a corridor-wide planning and implementation framework while our engineering teams are surveying, mapping and gathering information about existing conditions.
Planned activities for 2026–2027 include:
- Public input and engagement opportunities
- Detailed analysis of existing conditions
- Corridor alternatives development
- Development of a path toward shovel-ready plans for implementation
With community feedback and technical analysis, the goal is to create actionable plans that can move forward beginning in 2028.
What improvements are being considered?
Improvements being considered include better lighting, native landscaping, gateway and placemaking features, streetscape enhancements, and expanded multimodal transportation options.
When will road closures and traffic delays begin?
Phase One is about preparing for construction. The team will focus on studying existing road conditions, engaging with the community, completing design and utility work, and preparing the corridor for construction through 2027. Residents may see temporary traffic impacts as crews gather information. Any disruptions will be carefully scheduled and kept as brief as possible to minimize impacts on commuters, businesses, and local traffic. The team will work diligently to minimize right-of-way delays. Major construction is not expected to begin until late 2028.
Why is construction being completed in phases?
The corridor is divided into seven segments that will be planned and constructed in phases over approximately 10 years. A segmented and multi-phased approach is essential to keep a project of this size and magnitude moving forward while strategically managing traffic, minimizing disruption to businesses, residents, and commuters, and providing the ability to address the most critical needs along Louisiana-Johnston first.
Why is the Johnston-Louisiana Corridor project important to Lafayette?
The Johnston Street and Louisiana Avenue corridor is more than a road. It is a transportation and economic lifeline for Lafayette. The 8.5-mile corridor stretches from Interstate 10 at Louisiana Avenue to Ambassador
Caffery, connecting businesses, schools, neighborhoods, places of worship, movie theaters, and culinary destinations. It is also home to our Ragin’ Cajuns at the University of Louisiana at Lafayette, beautiful
Moncus Park, and the historic J. and L. Hebert Municipal Golf Course. As our city grows and welcomes new opportunities, now is the time to invest in and modernize this vital corridor at the heart of Acadiana — and the city we call home.
Will this project require a tax increase?
No. A new tax is not needed under our current funding approach. We will continue to build on our strong partnerships at the local, state, and federal levels and pursue available resources as the project advances. If we stay on track with those partnerships and Lafayette’s growth continues as expected, we believe the corridor can move forward without a new tax. A new tax is not on the table.
