Rail welding and power substation work begin on Stadium Way in late April

Publish Date
Body

Sound Transit's contractor will start welding rail segments on the east side of Stadium Way south of 4th Street as early as April 29. The contractor will bring in rail segments and store them on the east side of Stadium Way north of the 705 off-ramp. Crews will weld the segments together on Stadium Way south of 4th Street. Welding is a loud activity. The welded segments will be stockpiled on Stadium Way north of the 705 off-ramp. 

Saw cutting on Stadium Way to prepare for the rail. The contractor will begin cutting the pavement for the track on Stadium Way, starting at Division Avenue and going south to 4th Street. After the rail is welded, it will be installed first on Stadium Way in the area south of Division Ave. Rail installation could start in late May.

The traffic control for the rail welding and the saw cutting will be set up in advance. Northbound traffic on Stadium Way will continue to be open. Eastbound traffic on 4th Street will be closed from Broadway to Stadium Way for at least one month. Some rail segments will be stored on Stadium Way through the end of the year.  

Traction Power Substation on Stadium Way north of 4th St. As early as April 29, the contractor will begin construction on one of the substations that will power the trains. This substation is located on the west side of Stadium Way north of 4th Street near the stairs that go up the hill. Because of the steep slope, crews will first build a ramp on the hillside, and then will bring in a drill to build a retaining wall to create the pad for the substation. During construction, the stairs will be closed from Stadium Way to the landing mid-way up the hill. In addition, the crosswalk near this hillside will be closed across Stadium Way. Please walk on other routes in between Broadway and Stadium Way.
