Temporary changes coming for TriMet Line 15 as weight restrictions go into effect on the Morrison Bridge

Detour off bridge adds times to trips, leads to short-term detour in Mall 205/Gateway area

TriMet’s Line 15-Belmont/NW 23rd will detour off the Morrison Bridge as Multnomah County puts weight restrictions into effect until it can replace the deteriorating lift span deck on the bridge. Beginning Sunday, April 12, Line 15 buses will use the Hawthorne Bridge to cross the Willamette River. Seven stops on and around the Morrison Bridge will be closed, with temporary stops placed nearby to serve riders. The detour to the Hawthorne Bridge will also add about ten minutes to trips. As this is one of our Frequent Service lines, major delays would quickly stack up making trips later and later. To mitigate that and lessen the affect on riders and operators, TriMet must make both short-term and long-term adjustments to the Line 15.

Both spring and summer schedules are already in place for TriMet bus lines, so we will not be able to adjust schedules until the fall service change, which goes into effect September 13, 2015. At that time, long-term adjustments will be made to keep Line 15 buses running on a set schedule and allow for operator breaks until the line can return to the Morrison Bridge, which is tentatively scheduled for fall 2016.

In the short term, from April 12 through September 12, 2015, the Line 15 route will be adjusted and a new line will be added. Line 15 buses will travel directly between SE Washington/Stark & 92nd Ave and Gateway Transit Center, and will not serve the section of the route that goes to the SE Main St MAX Station, Portland Adventist Medical Center and the E 102nd MAX Station. The majority of the stops missed due to the detour, including the MAX stations, will be served by the new, temporary, Line 115-Cherry Blossom Loop. Riders will be able to transfer between Line 15 and Line 115 at Gateway Transit Center.

While the Cherry Blossom Loop line will maintain the same span of service as the Line 15, running from about 4:30 a.m. until 1 a.m. every day, the frequency will be different. During the peak travel times, from about 6 to 9 a.m. and 3 to 6 p.m. Monday through Friday, buses will run about every 15 minutes. Outside of those time periods, buses will run about every 30 minutes. Some stops along the loop route will temporarily close as the buses will travel a clockwise path along SE Cherry Blossom, 106th Ave, Main St, 96th Ave and 99th Ave (see map). Again, this loop will remain in service through September 12, 2015. For detailed service information and a full schedule go to trimet.org/alerts/line15detour.

Long-term Line 15 detour

The Line 15 will return to its regular route through the area on September 13, 2015 with an adjusted schedule to offset the added time of traveling across the Hawthorne Bridge. This will remain in effect until the Morrison Bridge reopens.
