DALE CITY – Virginia Department of Transportation (VDOT) structure and bridge crews continue work to replace a large stormwater pipe on Princedale Drive that failed after heavy rains on July 4, causing a sinkhole. The road is expected to remain closed between Saddler Lane and Roundtree Drive for four more weeks, weather permitting.

The 84-inch diameter galvanized metal pipe had been conveying water for a tributary of Neabsco Creek. After several inches of rain in a short period of time on July 4, the force of the water pushed the pipe into the creek, causing the asphalt above to fail.

Current Status

• Work was done on July 6 to relieve water pressure within the creek.
• Crews stabilized utility pipes on July 7.
• A hydraulic assessment was completed that recommended two 130’ long runs of 60-inch diameter concrete pipes to be installed, as well as new headwalls.
• On July 22, crews began pipe installation that is expected to continue through late August.
