TriMet's Morrison-Yamhill MAX Improvements project kicks off on Sunday, April 30. Crews will begin maintenance and rehab on some of Portland's oldest MAX alignment along SW Morrison and Yamhill streets at 11th and 1st avenues downtown.
This project will require a longer, three-week disruption to MAX service as well as a two-week disruption to Portland Streetcar. Crews will remove wood crossties, improve the track bed, upgrade switch machines and replace special trackwork. Further east, crews will replace curved rail at the corners of 1st and Morrison and 1st and Yamhill.
