Construction activity on the Mill Plain corridor continued at full speed in December, with more substantial work occurring at some locations as future BRT stations continue to take shape. Overall, construction remains focused primarily on the west side of the project corridor, between Fort Vancouver Way and 104th Avenue. As work progresses, station platforms and sidewalks are largely complete at numerous locations. Shelter structures have been installed at 20 locations. On the east end of the corridor and elsewhere, fiber and utility work continues to happen concurrently with station construction.
In December, crews installed four more shelter structures at future BRT stations. Workers also began construction at one new location in December: eastbound Mill Plain and Garrison Road. Workers also continued work on the new Mill Plain Transit Center at the east end of the corridor, near Mill Plain and 184th Avenue. The new facility will open as part of The Vine on Mill Plain, serving the new bus rapid transit line, plus other Local bus routes. Construction on the transit center will continue in the coming months as individual stations are built along the rest of the corridor.
Station construction will begin to shift to the east end of the corridor in January. Work will ramp up at two new locations on the east side: eastbound Mill Plain and 104th Avenue, and westbound Mill Plain and 126th Avenue. Meanwhile, work will wind down at other locations. That’s part of the phased approach to construction, so different locations see activity at different times. For fiber and utility work, activity will continue throughout the corridor.
