Plan ahead for lane reductions on State Route 99 Aurora Bridge overnight on June 4 and June 11

By Seattle Department of Transportation 

Over the next two weekends, Seattle Department of Transportation will install vertical posts in the middle of the State Route 99 Aurora Bridge. All work will happen overnight.

The posts help make the center line, which separates the northbound and southbound lanes, more visible. Installing the posts is a near-term safety improvement while we work with the Washington State Department of Transportation (WSDOT) to plan a larger, long-term corridor safety project. People driving are encouraged to take alternate routes and to maintain a safe speed if driving through the work zone. 

• From 10:00 p.m. on Friday, June 4 to 6:00 a.m. on Saturday, June 5, We’ll close the two middle lanes of the SR 99 Aurora Bridge to mark where the vertical posts will be installed on the bridge the following weekend. People driving are advised to maintain a safe speed if driving through the work zone. 
• From 10:00 p.m. on Friday, June 11 to 6:00 a.m. on Saturday, June 12, We’ll close the four middle lanes of the bridge to install the vertical posts. This will leave a single lane open in both directions. To minimize impacts, this closure is scheduled to coincide with a planned closure of the SR 99 Tunnel in downtown Seattle for routine maintenance.
