South Bellevue area

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. 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 after 12 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.

112th Avenue Southeast bypass road: During construction of the undercrossing, 112th Avenue Southeast will be reduced to one lane in each direction between Southeast 15th and Southeast 8th. People walking will use a sidewalk/pedestrian path on the west side of 112th Avenue Southeast. The map below, details what people walking, driving and riding bikes can expect. Please follow the direction of flaggers and signage to safely access your destination.

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: Sound Transit’s contractor closed the Bellevue Way SE 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 SE.

24-hour closure: The sidewalk on the west side of 112th Ave SE, between East Main and SE 6th is closed due to construction activities on the west side of 112th Ave SE. The sidewalk on the west side of 112th Ave SE between SE 8th and Bellevue Way SE is also closed. People walking are asked to follow the signed detour route, crossing at the signalized intersections located at Main Street, SE 6th, and SE 8th. The King County Metro bus stop located between Main Street and SE 4th has been relocated to a new location on the west side of 112th Ave NE, north of Main Street. The King County Metro stop located south of SE 4th has been relocated to a new location on the west side of 112th Ave SE, south of SE 6th.

24-hour closure: SE 15th Street is 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 AVE SE from SE 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.

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.
