The Broadway Bridge will be closed to all traffic, including motor vehicles, bicyclists and pedestrians August 21-23 from 6 am to 6 pm due to repairs to the lift span operating system. In August and September, Multnomah County is upgrading the old computer system that operators use to open and close the 108-year-old drawbridge. The current system was installed more than 20 years ago and replacement parts are no longer made.
The closure is the first of two weekend bridge closures required for the project. A second closure is planned September 18-20. Crews will conduct numerous, extended test openings of the drawbridge and make adjustments to the new system as needed. The drawbridge will be in the open position much of the day. The bridge will reopen to traffic each day by 6 pm.
The Steel Bridge is the nearest alternate crossing for bicyclists, pedestrians and motor vehicles. TriMet’s Broadway #17 bus will detour to the Steel Bridge during the closures. Portland Streetcar A and B Loop service will run across the Tilikum Crossing, turning back at NW 10th and NW Northrup on the west side and N Broadway and N Ross on the east side.

The Broadway is the third of four Multnomah County drawbridges to have its computer operating system replaced in recent years. The Hawthorne Bridge upgrade is scheduled for 2022. The Broadway Bridge is the largest drawbridge of its type, called a Rall Wheel Bascule, in the world.
