LogoInterstate 270 Corridor Study


I-270 traffic

What's new?

Over the past 18 months, MoDOT has been working on a high-level planning study to identify short and long-term needs and solutions on I-270 between McDonnell Boulevard and Route 367. Based on input from the community as well as traffic data , MoDOT has completed the final report, the first step in the process to develop this project. That final report is here.

The report highlights the needs, problems and opportunities along the I-270 North Corridor between McDonnell Blvd and Route 367. The corridor study is a high-level planning study to identify near- and long-term transportation needs on I-270 North and connecting roads. The conceptual drawings developed as part of this study were meant to illustrate the improvement concepts and need to be evaluated further during the environmental process. They do not indicate the exact locations or needed right of way for any possible future construction. The study team gathered and analyzed information to develop concepts to improve traffic flow, safety and efficiency along the corridor.

This study was the first step in the project development process.  MoDOT has funds for the next step -- the environmental study.  At this time, no funding is currently available for design or construction.

What's next?

The next step in the process is to conduct an environmental study, which looks at the potential impacts of the concepts being evaluated.  The study will look at I-270 in North St. Louis County from the I-70 interchange to just east of the Chain of Rocks bridge.  This study will take approximately 18 months and will include evaluting:

What is the problem?

Residents, commuters and commercial drivers have frequently expressed concerns about daily backups and congestion on roads connecting to I-270 in North Lindbergh between I-70 and the Chain of Rocks Bridge, especially during evening rush periods. These roads include Lindbergh, New Florissant Road and Route 367.

Interchanges, such as the one at 270 and Lindbergh, can no longer meet the increased traffic volumes in the area and must be improved. The entrance and exit ramps that require crossing oncoming traffic on Dunn Road are also noted as a major safety concern by motorists.

Several of the interstate bridges are old and need to be replaced. Access and accommodations for mass transit, bike and pedestrian use need to be upgraded.

Get Involved

Public meeting Residents and business owners encouraged to share their concerns about the corridor during this study period. MoDOT staff will visit with community leaders, churches, and civic organizations during this time to discuss the study and solicit input from the community.

In April, more than 50 North St. Louis County residents and business owners attended the first public meeting and shared their traffic and safety concerns about I-270 with MoDOT staff. This meeting was one method of gathering input from the community regarding how the interstate works in this area.

In May 2012, a second public meeting was held to share findings from the study, and to share conceptual drawings for several options. 

A community advisory group composed of business owners, community leaders and elected officials in North County is also providing input during the study process.

MoDOT will hold at least one public meeting during the enviromental study portion of the project development process. At this time, the date, time and place of that meeting has not yet been determined.
