Temporary closure of northbound I-5 off-ramp at 145th Street begins July 28, 2025

Starting Monday, July 28, phased closures of I-5 ramps to and from N 145th Street will begin as part of the City of Shoreline’s roadway improvements. 

These closures will lead up to a full shutdown of the N 145th Street overpass from Sept. 2 to Sept. 17, 2025.

During this time, crews will open a second lane on the northbound off-ramp to alleviate traffic backup and install a roundabout on the west end of the overpass. 

Once roads reopen, drivers will begin using the roundabout in a single-lane configuration. 

The east side of the overpass will remain signalized through late 2025.

Construction crews working for the City of Shoreline are working in the area Monday - Friday from 7am to 5pm. 

Access and detour information

The following will be closed from Monday, July 28 to Friday, Aug. 8:
  • The northbound I-5 off-ramp to N 145th Street.
The following will be closed from Monday, Aug. 25 to Wednesday, Sept.17:
  • The N 145th Street on-ramp to southbound I-5.
The following will be closed from Tuesday, Sept. 2 to Wednesday, Sept. 17:
  • The southbound I-5 off-ramp to N 145th Street.
  • N 145th Street between 1st and 5th Avenues NE. This includes the I-5 overpass.
Signed detours will take drivers east and west on N 155th and N 130th Streets. Northbound and southbound travel on Meridian Avenue N, 1st Avenue NE, and 15th Avenue NE will still be available. 

Pedestrian access over the 145th Street overpass will be maintained.

Drive slowly

As you navigate the detours and other nearby routes, remember that we all have a role in making sure everyone gets home safely. Bicyclists will share the detour routes and there are several crosswalks, so slow down and stay aware at the wheel. Construction workers will be close to live traffic, so it’s critical that we all set aside distractions and focus on the road.

    Article doesn't say whether the construction will be in 24 hour days or one 8 hour shift every day to complete. This is pertinent because the project is already behind schedule. With schools on 130th and 155th and opening during this process seems a little s-t-u-p-i-d

    Construction will probably be 7am to 5pm M- F with occasional weekend work. But the ramp will be closed 24/7.
