Eastbound Mercer Street between 5th Ave N and Dexter Ave N will be reduced to one eastbound lane under the Aurora/99 bridge over Mercer. One lane on eastbound Mercer Street will remain open to traffic.

Saturday, December 14th – Monday, December 16

Aurora/99 and eastbound Mercer will be fully closed to traffic beginning 3am Saturday, December 14 to Monday, December 16 at 5am for demolition of the western portion of the Aurora/99 bridge over Mercer. During the closure:

  • SR 99 will be fully closed to traffic between Valley St and the southern end of the Battery Street Tunnel. Traffic traveling through Seattle via SR 99 will be directed to I-5 in northern Seattle at 85th St or in southern Seattle at E Marginal Way and Spokane St. More information about alternate routes are online.
  • Eastbound Mercer will be fully closed to traffic between 5th Ave N and Dexter Ave N. Traffic heading east towards I-5 from Queen Anne will be detoured to eastbound Broad Street via Harrison Street and will reconnect to Mercer at 9th Ave N to continue towards the I-5 ramps at Mercer.
  • The sidewalk on Mercer will also be closed between 5ht Ave N and Dexter Ave N. Pedestrians will be detoured to Broad Street.
  • Broad Street and the I-5 on- and off-ramps at Mercer and westbound Mercer will remain open during the weekend work.

Per SDOT: Travelers can expect significant traffic congestion and should plan ahead and use alternate routes. Motorists attending performances at Seattle Center should allow for extra travel time, due to potential delays caused by detour traffic.
