State transportation department maintenance crews re-opened the Alaskan Way Viaduct and Battery Street Tunnel a few minutes before 5 p.m. Sunday, March 22.

The Battery Street Tunnel was scheduled to be closed until 5 a.m. tomorrow, but crews made good progress with necessary maintenance and inspections. The viaduct was closed for its semiannual inspections on March 21 and 22.

In addition to structural inspections, the state and the City of Seattle coordinated maintenance and preservation work during this closure.

This weekend crews:

Searched for and removed loose concrete on the viaduct
Repaired expansion joints and damaged bridge rails
Applied a protective covering to exposed rebar
Serviced drainage systems and traffic cameras
Washed the walls of the Battery Street Tunnel, and inspected the lighting and ventilation systems

The state plans to release preliminary inspection results on March 27, according to a news release.
