This project includes improvements to the northbound U.S. Route 63 entrance and exit ramps, Boone County Route AC (Grindstone Parkway), New Haven Road, and Lenoir Street. This area has been identified for enhancements due to increased congestion in the area. The work will also improve safety for all users and increase accessibility for bicyclists and pedestrians.

Project FAQs
What is the work taking place?
This project is being designed to expand traffic capacity on the east side of the Route 63/Grindstone Pkwy interchange, enhance safety for all users, and improve access for all users. Some local business' and the New Haven Elementary School entryways will be adjusted to improve traffic flow and safety.
When will work take place?
The project is scheduled to be put out for bids in fall 2023. Construction is tentatively scheduled to begin in early 2024 and completed by spring 2025.
What is the cost of the project?
Estimated cost is between $8-9 million.
Will the commuter lot be impacted?
This project will require the removal of the commuter lot located in the southeast corner of the interchange. Its removal will allow for the installation of the new loop ramp to Route 63. We are currently evaluating possibilities for relocating the commuter lot, but have not yet identified a suitable space.
Will additional right of way be required for construction of this project?
Yes. We are estimating the project will require the acquisition of approximately 15 acres. Based on our current timeline, right of way acquisition plans will be available in summer 2022.
Will the project include any work on the west side of the interchange?
No. For the near-term, traffic flow can be improved with only the work proposed on the eastern side of the interchange. The existing overpass bridge was just rehabilitated and is in good condition. The bridge is scheduled for replacement in 10-15 years, at that time we will examine further improvements to the interchange on the west side.
Project Milestones
MoDOT Central District held a virtual and in-person public hearing as part of the planning process of this project.
