PROJECT SCOPE:  Sewer Improvements

PROJECT IMPACTS: Starting Monday, September 29, crews will open one lane of flagger assisted westbound traffic at the 3200 – 3400 blocks of Williamsburg Avenue. This lane opening will be in effect from 7:00 a.m. to 10:00 a.m. Monday through Friday through December 2025.  Outside of these hours the traffic pattern will revert to eastbound only traffic for this stretch of Williamsburg Avenue between Stony Run Road and S. 31st Street.

PROJECT BACKGROUND: The CSO Outfall 004 Improvement Project on Williamsburg Avenue, part of Richmond's Combined Sewer Overflow Interim Plan, involves installing a larger pipe, manholes, a relocated outfall into Gillies Creek, and control structures to better manage flow. Once complete, it is expected to prevent about 48 overflow events and 5.1 million gallons of overflow annually. The project is fully funded by a $100 million ARPA grant.

Construction milestones include near completion of the CSO regulator structure and successful construction of the large diameter pipe tunneling in Williamsburg Road and under the railroad crossing. Due to unexpected underground conditions, the completion date has shifted from January 2025 to December 2025, though the project remains on budget.
