112th Ave SE temporary bypass road construction

Crews are preparing for the next phase of light rail construction on 112th Ave SE. Beginning next week, Sound Transit’s contractor will begin construction of the temporary bypass road near Bellefield Residential. When completed, the bypass road will carry traffic during construction of the road over rail undercrossing. Work to construct the bypass road is expected to last for approximately three months.

24 hours. During construction of the bypass road, 112th Ave SE will be reduced to one lane in each direction near SE 15th. People walking will continue to use the sidewalk on the east side of 112th Ave SE. 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.

Weekday construction traffic impacts: Monday, Aug. 6 – Friday, Aug. 10

Bellevue Way Southeast

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.

Monday-Friday 6 a.m. to 6 p.m. Work is set to begin on the light rail trench and guideway adjacent to Bellevue Way SE, between the South Bellevue Station site and the Wye at 112th Avenue SE. Throughout the project, two lanes will be maintained in the peak direction: northbound in the morning and southbound in the afternoon. Sound Transit’s contractor will use cones and lane delineators to guide traffic along Bellevue Way SE. Please follow the direction of flaggers and signage to safely access your destination. More info on what to expect can be found at the East Link long-term and ongoing closures click page.

112th Avenue Southeast

Monday-Friday 9 a.m. to 4 p.m. Daily closures of one southbound lane of 112th Avenue SE, between Main Street and SE 8th Street.
