New westbound SR 520 off-ramps coming Monday morning to Montlake

Let the countdown begin! At 5 a.m. Monday, July 17, we will open the newly aligned, permanent off-ramps to Montlake and Lake Washington Boulevards after a weekend-long westbound SR 520 closure.

Keep reading to learn more about the weekend highway closure and upcoming traffic switch.

What to expect this weekend:

  • Westbound SR 520 closure (11 p.m. July 14 – 5 a.m. July 17): All lanes and ramps of westbound SR 520 between 92nd Avenue Northeast and Montlake Boulevard will be closed.
  • SR 520 bicycle and pedestrian path closure: The path on the floating bridge will close for the weekend.
  • Round-the-clock construction: Crews will work around-the-clock to prepare the new off-ramps for traffic. Crews will also use the closure to remove part of an old ramp, add signs, adjust lighting and install plants.

What to expect Monday morning:

  • An earlier exit for the new westbound SR 520 off-ramps: At 5 a.m. Monday, July 17, the new westbound SR 520 off-ramps will open to traffic. Drivers will begin exiting SR 520 at the west end of the floating bridge, a mile farther east than they exit today. Drivers traveling to Roanoke or I-5 will remain on the west approach structure until the new westbound general-purpose and HOV/transit lanes open in August.
  • Continued construction access via the 24th Avenue East bridge: Contractor crews will continue to use the MOHAI staging area in Montlake through the end of the project. The stop sign and construction-only lane at 24th Avenue East will still be in place at the top of the Lake Washington Boulevard off-ramp.
