Upcoming East Link construction activities on 112th Avenue SE

Publish Date

Weekend closure of 112th Ave SE between Bellevue Way SE and SE 8th Street, April 7-8 and April 21-22

Weekday daily lane closures for utility work continue on 112th Avenue Southeast. In addition to the weekday work, Sound Transit's contractor is planning two weekend closures of all lanes on 112th Avenue Southeast, between Bellevue Way Southeast and Southeast 8th. The weekend closures are needed to relocate utilities in the roadway and perform utility crossings. Additional closures may be necessary to complete this work.

Anticipated closure dates:
  • Saturday, April 7th from 7 a.m. until 7 p.m. Sunday, April 8th.
  • Saturday, April 21st from 7 a.m. until 7 p.m. Sunday, April 22nd.

Local access to Bellfield Residential Park will be maintained. Flaggers and uniformed police officers will actively assist with traffic control and driveway access. Please follow the direction of flaggers and signage to safely access your destination.

Construction of the temporary bypass road and road-over-rail undercrossing

Road-over-rail undercrossing 60 percent design rendering.

Following completion of soil stabilization (Phase 1 - completed) and advance utility work (Phase 2), crews will begin building a temporary bypass road (Phase 3). The bypass road will serve one lane of traffic in each direction while Sound Transit's contractor builds the first section of the road-over-rail undercrossing.

A phased traffic control configuration will be used while crews build the bypass road and construct the road-over-rail undercrossing. Work to construct the bypass road is expected to last approximately three months. When ready for vehicle traffic, Sound Transit's contractor will use a full weekend closure to tie the bypass road into the existing 112th Avenue Southeast roadway. Once the bypass road is active, crews will start constructing the road-over-rail undercrossing (Phase 4 & 5); this phase of work is expected to last approximately eighteen months. In order to compete the final section of the road-over-rail undercrossing, traffic will be shifted from the bypass road onto the elevated roadway. The maps below give a general idea of the sequence and lane restrictions, but in general, drivers should expect portions of 112th Avenue Southeast reduced to one lane in each direction through the end of road-over-rail construction.
