Bellevue Way Southeast reversible lane configuration: In order to work in the eastside curb lane while maintaining two lanes of traffic in the peak direction (northbound 6-10 a.m. and southbound 2-6 p.m.) crews will use the 'southbound center lane' as a reversible traffic lane. At times, northbound vehicles will travel in what is normally a southbound lane.

Information graphic showing lane configuration changes on Bellevue Way.
The graphic above illustrates the direction of traffic flow throughout the day. Tail lights indicate vehicles traveling northbound and headlights represent vehicles traveling southbound. During all work activity the eastside curb lane will be closed and occasional mid-day closures (10 a.m. to 2 p.m.) of a second lanes may be needed. From 8 p.m. to 6 a.m. and during most weekends, all lanes will be open to traffic. 
6 a.m. to 10 a.m.: The eastside curb lane will be closed at 6 a.m., but work will not begin until 7 a.m. Two lanes of northbound traffic and one lane of southbound traffic will be maintained. Drivers needing to access 112th Avenue Southeast will need to travel in the furthest right open lane.

10 a.m. to 2 p.m.: Occasional closures of two eastside lanes. One lane of traffic will be maintained in each direction. Crews do not plan to close the second lane during the week of April 23rd. Typically when the second lane is not closed from 10 a.m. to 2 p.m., the 6 a.m. to 10 a.m. configuration maintaining two lanes of northbound and one lane of southbound traffic will continue until 2 p.m.

2 p.m. to 6 p.m.: The eastside curb lane will be closed. One lane of northbound traffic and two lanes of southbound traffic will be maintained. Occasional closures through 8 p.m., with work until 8 p.m. more likely between June and September.

24-hour closure: The sidewalk on Bellevue Way Southeast between the Wye at 112th Avenue Southeast and the South Bellevue Station site is closed. This closure will continue for approximately 2 ½ years; people biking and walking should seek alternate routes.

24-hour closure: Starting Monday, April 16, Sound Transit's contractor closed the Bellevue Way Southeast to I-90 west HOV ramp. This closure is necessary to provide a safe work area and maintain safety for the traveling public. During the closure, crews will construct elevated columns and pier caps adjacent to and over the ramps from I-90 to Bellevue Way Southeast.

24-hour closure: The sidewalk on the west side of 112th Avenue Southeast, between East Main and Southeast 6th is closed due to construction activities on the west side of 112th Avenue Southeast. The sidewalk on the east side of 112th Avenue Southeast between Southeast 8th and Bellevue Way Southeast is also closed. These sidewalk closures may shift to the opposite side of the street as work progresses. One sidewalk will be maintained during utility work. People walking are asked to follow the signed detour route, crossing at the signalized intersections located at Main Street, Southeast 6th, and Southeast 8th. The King County Metro bus stop located between Main Street and Southeast 4th has been relocated to a new location on the west side of 112th Ave Northeast, north of Main Street. The King County Metro stop located south of Southeast 4th has been relocated to a new location on the west side of 112th Avenue Southeast, south of Southeast 6th.

24-hour closure: Southeast 15th Street has been closed and will remain closed for approximately three years, as crews prepare the area for construction of the road-over-rail crossing. Workers and visitors wishing to access Bellefield Office Park can use 114th Avenue Southeast from Southeast 8th Street.

24-hour closure: The parking lots at the Winters House and Blueberry Farm are closed for East Link construction. Access to Mercer Slough Park and the trail system will remain open. During the closure, parking is available at a new temporary parking lot located near the South Bellevue Station site. The new lot is for Mercer Slough Park users and a three-hour maximum will be enforced. Commuter parking will NOT be allowed at this lot.

On Monday Oct. 9, Sound Transit will begin a long-term closure of a portion of 110th Avenue Northeast between Northeast 4th and Northeast 6th streets. The closure is needed to build the Link light rail north tunnel portal near Bellevue City Hall.

The closure on 110th Avenue Northeast will occur in multiple phases:

Phase 1 (October 9, 2017 - approximately Spring 2018). Scheduled to last about nine months, phase 1 requires the closure of all lanes on 110th Avenue Northeast illustrated in the work area graphic. Access to the City Center Plaza parking garage will be maintained.

Phase 2 (approximately Spring 2018 – Winter 2018). One lane of traffic on 110th Avenue Northeast will be reopened in both the north and southbound direction.

Phase 3 (approximately Winter 2018 – Spring 2019). Phase 3 again requires a full closure of all lanes on 110th Avenue Northeast in the work area as utilities are reinstalled and the roadway restored.

Last summer, Sound Transit's tunneling contractor closed a larger portion of 110th Avenue Northeast to prepare the soil underneath the roadway for tunneling and construction of the north tunnel portal.

This fall's closure footprint is similar, but smaller compared to what was previously in place. City Center's parking garage access from 110th Avenue Northeast will be maintained, whereas it was closed during the previous work.
