Underground utility work begins in the Hilltop Business District next week

Publish Date

Sound Transit's contractor will start installing underground utilities (sewer, stormwater and water) at 11th Street and Martin Luther King Jr. Way as early as March 18. This work will involve digging trenches in the street and installing pipes and manholes underground. 

Crews will work first on the sewer line in the center of S. 11th St. east of Martin Luther King Jr. Way. The intersection of MLK Jr. Way and 11th St. will be temporarily closed to install a manhole. One-way traffic westbound on 11th Street will be maintained. The eastbound traffic lane from Martin Luther King Jr. Way to I Street will be temporarily closed. Please follow detours. In addition, the pedestrian island located west of Martin Luther King Jr. Way will be temporarily closed.

After the sewer work, crews will do the stormwater and water line work at 11th St. and MLK Jr. Way.

When the utility work at 11th and MLK Jr. Way is completed, crews will work on underground utilities along MLK Jr. Way from 11th to 14th Street. We will keep you informed of this next stage of work.
