Key construction impacts


Project timeline

In summer 2014, crews expect to complete three highway lids, two transit stations and the final SR 520 roadway alignment.

SR 520 median transit stops

Construction of the Evergreen Point Road and 92nd Avenue Northeast median transit stops will continue through the first months of this year, with the stops scheduled to open in early summer. The highway’s existing eastbound and westbound transit stops will close and the median transit stops will open at the same time to ensure uninterrupted service and the safety of users and bus drivers. After the median transit stops open, bus drivers will use the bus lanes in the median of SR 520 to access the stations.


Planting has begun throughout the project corridor and will continue through the completion of the project. After project construction is complete, you may still see crews maintaining project landscaping for the next three years to ensure plant growth. Crews began planting near Bellevue Way last fall, including installing nearly 20 raptor perches to encourage habitat development (read all about it on the WSDOT Blog). Crews will plant shrubs and grass on the Evergreen Point Road lid in late winter and will then move east, planting shrubs, grasses and trees throughout the corridor as soon as roundabouts and roadways are moved into their final alignment.

Regional bicycle and pedestrian trail

Crews continue to build the pedestrian trail on the north side of SR 520 between 108th Avenue Northeast and the floating bridge. Because the path currently provides crews access to the construction zone, it will be one of the last features to open to the public.

Evergreen Point Road lid features wrap up, transit stop work continues

Crews opened the sidewalk across the west side of the new Evergreen Point Road lid in December 2013. Construction of the transit stop, park-and-ride lot, landscaping and sidewalk along the east side of the lid continues. Lid features are scheduled to be complete in spring 2014. Construction of the transit stop will continue through the winter, opening in summer 2014 at the same time as the 92nd Avenue Northeast median transit stop.

Expect 84th Avenue Northeast roundabout construction and road impacts this spring

Crews are getting closer to opening the 84th Avenue Northeast roundabout and expect to complete construction in early summer 2014. Expect impacts to local traffic as crews complete the final phases of construction in late spring. Stay tuned for more information about traffic impacts and sign up for more information and email updates about traffic impacts here.

92nd Avenue Northeast roundabout and pedestrian tunnel construction continues

Crews began clearing trees and shrubs in mid-March on the north side of the 92nd Avenue Northeast lid they are building over SR 520. Crews will switch traffic flow several times over the spring and summer months in order to complete the roundabout structure. Check out the 92nd Avenue Northeast roundabout construction detour route information here.

Work on the 92nd Avenue Northeast median transit stop will continue through summer. This transit stop is scheduled to open this summer at the same time as Evergreen Point Road’s new in-median transit stop. 

Northeast Points Drive roadway, gate and wall complete this spring

Crews are currently finishing the median barrier wall and emergency access gate on Northeast Points Drive west of 96th Avenue Northeast. Crews expect to complete the sidewalk and curb on Northeast Points Drive in the coming months. Crews expect to place the final layer of pavement in early spring 2014 and crews will continue installing landscaping through summer.

Bellevue Way bridge opens this spring

Bellevue Way bridge construction will continue through early spring 2014. Crews will complete this bridge before opening the 84th Avenue Northeast roundabout so that traffic can use the new bridge to enter and exit SR 520 while the 84th Avenue Northeast roundabout is being completed. The improved bridge provides additional capacity, including two through lanes in both directions on Bellevue Way, two left-turn lanes on Northup Way, and double left-turn lanes off northbound Bellevue Way onto SR 520 (with longer left-turn lanes to help separate traffic headed onto SR 520 from traffic continuing on Bellevue Way. Additionally, a pedestrian and bicycle path will open along the east side of Bellevue Way following the completion of the bridge.

108th Avenue Northeast construction ramps up

Construction is ramping up at the intersection of 108th Avenue Northeast and Northup Way. Crews are preparing to install utilities and build two new noise walls on the northeast and northwest corners of the intersection. The improved intersection will feature updated drainage and utilities, as well as a 12-foot-wide sidewalk on the south side of Northup Way for improved pedestrian and bicycle access.

Crews will open the new westbound SR 520 crossing over 108th Avenue Northeast and remove the existing bridge. The new bridge allows crews to build the direct-access HOV and bus lane, which will provide buses with a safer, more reliable route through the SR 520 corridor to the new median transit stops at 92nd Avenue Northeast and Evergreen Point Road.

Eastside progress leads to additional temporary HOV-lane restrictions east of I-405

As construction progress continues eastward along the SR 520 corridor, Eastside Transit and HOV Project crews are moving forward with highway widening and HOV improvements in the Bellevue Way and 108th Avenue Northeast area. To complete this work, which includes building HOV lanes in both directions and direct-access ramps for buses and carpools at 108th Avenue Northeast, crews have temporarily shifted westbound buses and carpools into the two general purpose lanes beginning just east of I-405.

Temporarily removing the westbound HOV lane has allowed crews the work area needed to build the future highway lanes and HOV improvements. The existing bus-only lane between 92nd Avenue Northeast and Evergreen Point Road will remain in place.

The westbound HOV lane, along with a new eastbound HOV lane and direct-access ramps, will reopen when the project is complete, scheduled for summer 2014. 

SR 520 westbound HOV lane during remainder of Eastside project construction

  • SR 202 to 108th Avenue Northeast – Westbound HOV lane remains open
  • I-405 to Evergreen Point Road – Westbound HOV lane closed until project completion, scheduled for summer 2014
  • 92nd Avenue Northeast to Evergreen Point Road – Bus-only lane remains open for the remainder of project construction

Traffic Revision: 108th Avenue Northeast on-ramp to westbound SR 520

Since May 30, 2012, there has been a change at the 108th Avenue Northeast entrance to westbound SR 520. Here are the details:

Northbound 108th Avenue Northeast to westbound SR 520:

  • This access is closed permanently.
  • Drivers will instead access westbound SR 520 at Bellevue Way, via Northup Way.

Southbound 108th Avenue Northeast to westbound SR 520:

  • No change.

This change was made for construction of the new on-ramp and a fish-friendly culvert underneath 108th Avenue Northeast. When complete, the new 108th Avenue Northeast interchange will include direct-access ramps for buses and carpools traveling in both directions on 108th Avenue Northeast.

Points Loop Trail detour

The Points Loop Trail is closed between Evergreen Point Road and 84th Avenue Northeast while crews construct project improvements. Bicyclists and pedestrians are to use the detours to Northeast 28th Street and Northeast Points Drive. A section of the reconstructed Points Loop Trail was opened in fall 2013 between 84th Avenue Northeast and 92nd Avenue Northeast.
