Motorists and pedestrians should prepare for road closures and detours in several areas of Richmond next week as the city conducts its annual floodwall testing.

Beginning Saturday and running through June 7, the Department of Public Utilities will perform operational testing on the city’s floodwall system from 7 a.m. to 2 p.m. daily, weather permitting.

The Mayo Bridge will be shut down to all vehicular and foot traffic on June 1 and 2 while testing occurs at that location.

Southbound traffic will be able to access the island on June 1, while northbound can reach the island on June 2.

Additional testing will require these road closures:

• June 5: East Byrd Street between South 12th Street and Virginia Street from 8 to 10 a.m.; Dock Street from 18th to 21st Street from 11 a.m. to 1 p.m.

• June 7: Cary Street between 20th and 22nd Street from 7 a.m. to 2 p.m.

Motorists are advised to obey road closure and detour signs in the area for safety. Pedestrians are not permitted in the testing zones.

The annual inspection ensures operability of the floodwall gates in accordance with Army Corps of Engineers standards.

The last closure was a precautionary measure in November 2020 due to heavy rainfall.
