Since September, crews have been constructing a new westbound SR 520 off-ramp to East Lake Washington Boulevard at the 24th Avenue East bridge crossing over SR 520. Crews plan to open the new off-ramp next month which will include two, new stop-controlled intersections. Here’s what to expect:

  • Nighttime SR 520 closure for traffic switch: The night before the new off-ramp opens, crews will close all lanes and ramps of westbound SR 520 between 92nd Avenue Northeast and Montlake Boulevard to switch traffic onto the new off-ramp. We will communicate the exact date of the overnight closure and traffic switch once it’s set.
  • Existing westbound SR 520 off-ramp to Lake Washington Boulevard East through the Arboretum to permanently close: This ramp will be closed during the traffic switch and removed later to accommodate the new West Approach Bridge North. All drivers exiting westbound SR 520 to Lake Washington Boulevard will use the new westbound off-ramp at the 24th Avenue East overpass.
  • Temporary off-ramp configuration during construction: The new westbound SR 520 off-ramp to East Lake Washington Boulevard will open in a temporary configuration. This will provide a separate traffic lane on the 24th Avenue East overpass for construction vehicles to access the nearby construction staging area at the former Museum of History and Industry site.
  • Added stop signs to control traffic: Drivers exiting the new off-ramp must stop at two locations to reach East Lake Washington Boulevard. First, drivers will be required to stop at a new stop sign at 24th Avenue East to allow construction vehicles into the nearby staging area. They’ll be required to stop again at a new 4-way stop at the East Lake Washington Boulevard intersection. Drivers can turn either left or right onto East Lake Washington Boulevard to reach their destination. As drivers adjust to the new off-ramp, WSDOT will work with the city of Seattle to monitor traffic conditions and, as needed, adjust signal timing on Montlake Boulevard.
  • Weekend closure after off-ramp opens: Later in 2016 after the new off-ramp opens to traffic, crews will need a full closure of SR 520 to remove a section of the existing westbound SR 520 off-ramp that spans over SR 520. We’ll announce this weekend-long highway closure once the date is confirmed.
