The Burnside Bridge will be closed to all traffic from 6 am to 6 pm on Saturday and Sunday on the weekends of:

  • January 16-17

  • January 30-31

The closures will allow Multnomah County to replace a degraded computer control system used to operate the movable lift span. The work requires frequent openings of the drawbridge.

Bridge users (including bicyclists and pedestrians) should use alternate routes such as the Morrison and Steel bridges during the closure.  TriMet bus lines 12, 19 and 20 will detour to the Steel Bridge when the Burnside Bridge is closed. The Burnside Bridge will reopen to traffic as soon as the work is completed.

Upgrading the lift span will also impact river traffic, since only one of the two drawbridge leafs is operable during the work. The west leaf is out of operation until midnight on January 17.  The east leaf will be out of operation from midnight on January 17 until as late as midnight on February 7, when the project is scheduled to be complete. River traffic can request a tugboat assist if needed by contacting the Hawthorne Bridge operator.

The Burnside Bridge is the county’s second bridge to have its lift span controls upgraded, following the Morrison Bridge in 2019. After the Burnside work is complete, the county will upgrade the lift span controls on the Broadway Bridge later this year. The Hawthorne Bridge will be the last county drawbridge to be upgraded, sometime in the next two years. 

Multnomah County maintains the Burnside Bridge and five other Willamette River bridges. For more information, visit www.multco.us/bridges or follow us on Twitter @MultCoBridges.
