As you drive up Main Road, do you wonder what is going on and when it will be finished?
According to the Main Road Corridor Segment A Newsletter, the project begins at Bees Ferry Road, continues along Main Road across US 17, and ends at the intersection of River Road and Chisolm Road.
The goal of the project is to relieve severe traffic congestion and improve hurricane evacuation. Key features for this corridor include:
- The Flyover: New interchange flyover ramps constructed from US 17 to Main Road.
- Main Road Widening: Widening Main Road from two to four lanes from Bees Ferry Road to the River Road/Chisolm Road intersection.
- Roundabout & Railroad: A new roundabout at Main/River/Chisolm roads and a replacement bridge over the CSX Railroad.
- Shared-Use Paths: 12-foot-wide paths running throughout the corridor.


The project has several deadlines:
- Construction of the Main/River/Chisolm roundabout will begin in Q2 2026.
- Drilled shaft work for all ramps will begin in Q2 2026.
- Final plans for the Old Pond Road turn lane are expected in Q3 2026.
- The ramp 3 tie-in to US 17 construction will be completed by Q4 2026.
- Ramp system construction continues.
- Utility coordination and relocations continue.
