I-270 Corridor Study

History and Background

 

In 2005, the Board of Directors of the East-West Gateway Council of Governments adopted Legacy 2030, the transportation plan for the St. Louis region.  The plan recommended a study of the I-270 corridor in North St. Louis County.  Several important factors and trends were considered in making this recommendation: increased traffic volumes and crashes as contributors to safety problems along the corridor; aging and outdated infrastructure; and the growing and significant role  I-270 plays  in commercial freight movement  (for both regionally-generated and cross-country freight ) and in commuter travel.

In 2009, MoDOT staff met with local government officials and the Transportation Committee for North County Incorporated, to discuss the growing need for a study of this segment of I-270 in North St. Louis County. 

Recently, MoDOT worked with the East-West Gateway Council of Governments and others to prioritize the region’s major transportation system improvement needs; and to determine how best to fund those needs. Stakeholders consistently pointed to the northern area of I-270 as one of the region’s top priority corridors in need of improvement.

The focus of the study was the approximately 12-mile stretch of I-270 in North St. Louis County, between McDonnell Boulevard and Route 367.

This high-level study fully investigated the complex factors affecting traffic flow and safety in the area. This work was performed by MoDOT staff, with resource support from the East-West Gateway Council of Governments (EWGCOG), Metro and others stakeholders.  

 

The following interchanges were included in the study:

  • I-270 interchange with McDonnell Boulevard (Blvd.); and McDonnell Blvd., from Campus Parkway to Dunn Road;
  •  I-270 interchange with Lindbergh Blvd. (67); and Lindbergh Blvd. from Fee Fee Hills to Lindsay Lane/Patterson Road;
  • I-270 interchange with I-170;
  •  Hanley Rd., from Airport Rd. to St. Anthony;
  •  I-270 interchange with New Florissant Rd.; and New Florissant Rd., from McCluer High School to St. Anthony Lane;
  • I-270 interchange with Washington St. /Elizabeth Ave.; and Washington/Elizabeth, from  Pershall Rd. to Dunn Rd;
  • I-270 interchange with West Florissant Ave.; and West Florissant Ave., from Hudson to Route AC (New Halls Ferry Rd.);
  • I-270 interchange with New Halls Ferry; and New Halls Ferry Rd., from Old Halls Ferry to West Florissant;
  • Old Halls Ferry Road, from Route AC (New Halls Ferry Road) to Netherton Drive;
  • I-270 interchange with MO Route 367; and MO Rte. 367, from Veterans to Dunn Road.
  •  Bellefontaine Road, from Aldi’s to Larimore Parkway

As part of that study, MoDOT held two public meetings.  At the first, held in April 2011, MoDOT identified the existing problems and took input from the community on potential solutions and contributing factors to the issues in the study area.  This informaiton was presented during the first public meeting:

The following comments were collected from the public during this public meeting:

MoDOT held a follow up public meeting in May 2012 to discuss the initial findings of the study and outline the next steps in the environmental study process.  The department presented two conceptual alternatives, based on the study, and on input from the community.  Information presented at that follow-up meeting included:

 The following documents are more conceptual drawings based on the two recommendations developed as part of the study. The conceptual drawings developed as part of this study are 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. At this time, no funding is currently available for design or construction

Recommendation 1 - I-270 improvements where existing outer roads (Dunn and Pershall) remain

Recommendation 2 - I-270 improvements in which the outer roads (Dunn and Pershall) are converted to one way
