| By DES Communications

Barricades indicate a closed road on the Capitol Campus.

Water Street and 11th Avenue Southwest to close Sept. 16 until early November.

What

DES is installing a vehicle barrier at a key entry point to West Campus. The barrier, which is level with the roadway, can be raised in the event of a threat to the safety of Capitol visitors, workers, or public officials. 

Where

Water Street and 11th Avenue Southwest, between Cherry Lane Southwest and Columbia Street Southwest, on the West Campus. 

When

Work began in mid-Sept. and is expected to end Friday, Dec. 13. 

Impacts

DES will close Water Street Southwest and a portion of 11th Avenue Southwest. Traffic bound for the following areas can continue to use the North Diagonal, South Diagonal, and Sid Snyder Avenue: 

  • Governor’s Mansion 
  • Temple of Justice 
  • Legislative Modular Building 
  • Flag Circle 
  • Adjacent parking areas 

Traffic leaving these areas will travel south along Cherry Lane to Sid Snyder Avenue. During the street closure, parking on the west side of the General Administration Building is back-in only.

An illustrated map indicating Water Street is closed between the Columbia Street and Cherry Lane. A detour is marked along Columbia Street (near the Helen Sommers Building), Capitol Way, the North Diagonal, and Cherry Lane (near the Temple of Justice).
During the closure, the North Diagonal is the nearest alternate westward route.
