The section marked in red will be closed the next two Saturday nights. The section marked in blue will be closed December 12 until the next morning. The marked on-ramps will also be closed.

Getting to and from Beacon Hill via Interstate 5 could be a bit more difficult over the next couple of Saturdays. Six miles of northbound I-5 through south Seattle will be closed on the next two Saturday nights for workers to install new overhead sign bridges.

All lanes of northbound I-5 will be closed from 11:30 pm Saturday, December 5, to 8:00 am Sunday, December 6, between Boeing Access Road and Spokane Street. On-ramps in the area will start closing as early as 9 p.m.

These ramps will be closed from 9:00 pm Saturday to 8:00 am Sunday:

  • Boeing Access Road and Martin Luther King Jr. Way S. to northbound I-5
  • Swift Avenue S./S. Graham Street to northbound I-5
  • Corson Avenue/S. Michigan Street to northbound I-5

The following Saturday, all lanes of northbound I-5 will be closed from 11:30 pm December 12 to 8:00 am December 13 between Boeing Access Road and I-90.

There will be a signed detour to direct drivers to exit at Martin Luther King Way (exit 157) to Airport Way, and back onto I-5 via Edgar Martinez Drive/SR 519. Consider taking alternate routes like I-405 or SR 99 to avoid long delays and backups.

You can see more about the new overhead sign bridges here. The sign bridges are funded by the Alaskan Way Viaduct program, and are intended to improve traffic flow during the demolition and replacement of the Viaduct. The signs will be activated next summer.
