What is the problem?

The interchange of I-44 and Route 141 is exceptionally crowded during morning and evening commutes.  With several major arterials, including Vance, leading to Route 141 near I-44, the roadway remains exceptionally congested.

What is the  current situation?

MoDOT will hold a public meeting  from 4 - 7 p.m. on May 18 at the Field House at the Valley Park School District to share information about the project and the expected impacts of construction. To view information presented during the public meeting, please click here.

In January, The Missouri Highways and Transportation Commission selected Pace Construction and its partners as the team with the project which provides the best apparent value for this project. 

One of the major goals of the project is to improve how efficiently traffic flows between I-44 and Route 141.  In addition, the department is looking to improve how effiently traffic in the area moves through to Vance.

The project selected as the apparent best value constructs a flyover ramp from southbound Route 141 to eastbound I-44 and makes significant interchange improvements for northbound and southbound Route 141 to westbound I-44.  There will also be improved drainage to reduce flash flooding around the interchange.

In addition, the project will improve left turns to Marshall and Vance Road using signalized through-turns. In a through turn, drivers pass the roadway and loop to an outside lane at the signal to make the turn onto the roadway.  This means less time waiting at a signal during peak traffic periods and improves the flow of traffic.  According to Federal Highway studies, this type on intersection reduces crashes by nearly 40 percent, making it much safer.

Most of the construction will take place during non-peak traffic hours, so it should not impact rush hours through the area significantly.  There are no long-term closures scheduled for either Route 141 or I-44.

Construction is expected to begin later this year, and will be complete by mid-2018.

 

How was the contractor team selected?

MoDOT selected Pace Construction using a process called design-build.  This process, similar to that used for the New I-64 project, the Daniel Boone Bridge and the Route 364 Phase 3 project, involves hiring one contracting team to design and construct a specific highway project. This technique has been known to significantly save time and provide cost savings

As a part of design-build, MoDOT sets the project goals and budget and the potential contractors determine the design work and schedule based on those goals.  The winning contractor is the one that best meets the stated goals within the project budget.

Since the project is design-build, the specifics on what the project will look like and how the project will be staged is determined by the winning contractor. 

What are the goals for the project?

  • Deliver the project within the program budget of $25 million.
  • Maximize mobility on Route 141 and improve efficiency at the I-44 interchange and Vance Road intersection.
  • Deliver the project in a manner which demonstrates the importance of safety.
  • Provide a quality project resulting in a long-lasting transportation facility that minimizes future maintenance.
  • Deliver the project using a diverse workforce.
  • Complete the project by July 15, 2018.

Community Involvement Group presentationsNew

MoDOT has established a Community Involvement Group, where the department is reaching out to community leaders impacted by the project.  The intent of the group is to be one avenue of sharing information, and allowing these leaders to share the information with their constituents or employees.
