Coming Soon: Route 644 (Rock Hill Church Road) Bridge Installation

Traffic on Route 644 (Rock Hill Church Road) in Stafford County is currently crossing a temporary, single-lane bridge over Aquia Creek. Installation of a new two-lane bridge is scheduled to begin in 2025 and will open to traffic in 2026.

The temporary bridge was installed in fall 2020 after a bridge inspection found deterioration in the bridge’s major elements. The temporary bridge was installed to allow through traffic to continue while the replacement bridge project was funded and designed. 

The temporary bridge can carry vehicles up to 40 tons, including emergency vehicles and school buses. Without the temporary bridge, the existing bridge would have been posted with an 11-ton weight limit.

During the bridge replacement project in 2025-2026, Rock Hill Church Road would be closed to through traffic between Dunbar Drive and Van Horn Lane with a detour in place. 

The existing bridge was built in 1950 and underwent a major reconstruction in 1978.

Around 2,000 vehicles a day travel on Rock Hill Church Road, according to a 2019 VDOT traffic count.

Benefits 

Temporary bridge maintains ability for vehicle of all legal loads to continue traveling on Rock Hill Church Road while a replacement bridge over Aquia Creek is designed. 

Replacement bridge will have two travel lanes

Vehicles of all legal loads can cross replacement bridge when it opens to traffic
