MoDOT Kansas City is in the process of replacing the Prospect Ave. Bridge over Interstate 70. This bridge is considered in poor condition and is nearing the end of its service life. This project also includes improvements to the interchange ramps and 14th Street. Additionally, this project will honor the commitments of the Second Tier I-70 Environmental Impact Statement.

Project Goals

  • Replace bridge in an economical manner while increasing vertical clearance over I-70.
  • Maintain traffic flow on I-70 and viable detour routes of Prospect during construction.
  • Coordinate with the future I-70 Corridor project.
  • Minimize ROW impacts.
  • Improve safety and operations of Prospect with I-70 and local roads.
  • Accommodate KCMO long-term corridor plans and KCATA Prospect MAX route.
  • Incorporate pedestrian and non-motorized user facilities.
  • Communicate with local community and obtain stakeholder support for project.


 Construction began in summer 2023 and should take approximately 5-6 months. The project was on April 21, 2023, and was awarded to Radmacher Brothers Excavating Co., Inc. The cost of construction is estimated at $7.3 million and is part of MoDOT's Statewide Transportation Improvement Plan.


The Prospect Ave. Bridge over I-70 will be CLOSED to through traffic during construction. Chestnut Ave. will be used as a local detour. Busses will be re-routed and the ramps will be closed to traffic as needed. More details on traffic impacts are announced as work progresses.
