About the Project

This project will reconstruct the interchange at I-66 and Route 15 (James Madison Highway) to relieve congestion, enhance safety and capacity, and accommodate forecasted traffic demand in the area. Two concepts are being considered:

Based on engineering and operational analyses, the preferred alternative selected was a a semi-directional ramp to facilitate southbound Rt. 15 traffic to eastbound I-66, along with modifications to the existing ramp terminal intersections (click here to see the layout). Preliminary design is underway.

The project also includes improvements to the Rt. 15 intersections at Heathcote Boulevard and Route 55, and a shared-use path along the eastern side of Rt. 15.

See the project brochure for more details.

Project cost

Preliminary engineering - $6 million
Right of way acquisition, relocation assistance and utility relocation - $10 million
Construction - $62 million
Total - $78 million

This project will be financed with federal and state funds. Costs are subject to change since project development is in the early design stage.

Semi-directional ramp concept and renderings (preferred alternative) – A semi-directional ramp to facilitate southbound Rt. 15 traffic to eastbound I-66, along with modifications to the existing ramp terminal intersections.
Single-point urban interchange concept – A single-point urban interchange with a single central traffic signal replacing the two existing ramp terminal signalized intersections.
