MLK between South 15th and South 19th will maintain two-way traffic during construction of underground utilities. The intersection at South 16th Street and MLK will be closed while the contractor connects the side sewer to the main line. Parking will be restricted on both sides of MLK as well as on South 16th for a half-block just west of MLK. Please move your vehicles during the times shown on the no parking signs – thank you. Pedestrian access will be limited in these areas.

Commerce Street: 7th St. to I-705 on-ramp – lane restrictions. Access to Commerce Street from the 705/Stadium Way exit is closed until mid-January 2019. Detours are in place. One-way traffic northbound on Commerce Street will be maintained from South 9th to 705 until January. The contractor is installing a new sewer.

Please follow the detours on St. Helens Avenue, Broadway and Tacoma Avenue. One-way traffic going north on Stadium Way is open. The pedestrian refuge islands on Stadium Way were removed as part of the project and to better shift traffic during construction.

Creating foundations for power poles on Martin Luther King Jr. Way

To provide electricity for the light rail vehicles, Sound Transit's contractor will install poles which provide overhead power lines (known as the overhead contact system or OCS) that will be needed to run the train. Creating foundations will consist of cutting the street or sidewalk, removing concrete or asphalt, drilling a hole, installing rebar, and then pouring concrete. There will be no parking near the foundations while the work occurs.

The contractor will start foundation work for the OCS poles on Martin Luther King Jr. Way in between 16th Street and 19th Street as early as Dec. 17.

Replacing water line in front of Stadium High School

Sound Transit's contractor will replace the water line in front of Stadium High School during winter break when students are not at school, starting Dec. 26th. The work will be completed by the time school resumes on Jan. 3. Water service will not be affected during this time. Customers will continue to have water. 

In late-January to early-February, Tacoma Public Utilities crews will make the final connections of the newly installed water main. A TPU representative will coordinate the short duration water shutdowns with customers.
