The Burnside Bridge will be closed to all traffic from 6 am to 6 pm on Saturday and Sunday on January 30-31 while a Multnomah County crew install a new computer system to operate the movable lift span. The work requires frequent openings of the drawbridge. The weekend closure is the final one needed to complete the project.
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 also impacts river traffic, since only one of the two drawbridge leafs is operable until the project is completed on February 7. 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. 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, in the next two years.
