Route 419/220 DDI

Route 419/220 Interchange - Mark Morrow

This project will reconstruct the Route 419 (Electric Road) and Route 220 interchange to a Diverging Diamond Interchange (DDI). The planned DDI will eliminate the northbound Route 220 circular ramp and shift drivers to the opposite side of the road to use the other existing northbound ramp to Route 220. Traffic light phases will also be reduced, helping to move traffic through the intersection. Sidewalk will be constructed to complete the gap between planned sidewalk along Tanglewood Mall’s frontage and sidewalk along the north side of Franklin Road in the City of Roanoke. Bicycle facilities will connect future bicycle lanes on Route 419 to existing bicycle lanes on Franklin Road. Learn more about Diverging Diamond Interchanges.

Project Status

The $17.5 million project is funded with Surface Transportation Block Grant (STBG) and SMART SCALE funding. Preliminary Engineering is underway and construction is anticipated in 2024.
