Currently Buckner-Tarsney/Main Street, also known as State Route AA, restricts regional flow and limits economic development within the City of Grain Valley’s downtown corridor. This project will carry improvements through Grain Valley’s downtown area. This project breaks ground in 2015.

Citizens are pleased with the progress on the current project, and hope to continue in a successful partnership with MoDOT. This will be accomplished through the following improvements:

  • Modify portions of Buckner-Tarsney (Route AA) to two-through lanes and a center two-way left turn lane.
  • Provide a multi-use path on the east side of the road, and a standard sidewalk on the west side with enhanced crosswalks.
  • Upgrade street lighting.
  • Provide a new roadway surface with curb, gutter and drainage improvements.
  • Upgrade a railroad crossing within the project limits.

The approximately $3 million project began design in June 2013 with an anticipated construction start date of spring 2015.
