The Morrison Bridge will reopen by 8 p.m. on Sunday, Aug. 6, a postponement of its scheduled reopening on Friday, Aug. 4 due to additional time needed for the concrete to set. The bridge closure is imperative since the vibrations from traffic can damage the new concrete while it heals and hardens. 

The closure impacts motor vehicles, bicyclists and pedestrians. While the Morrison Bridge is closed, traffic will be impacted on nearby bridges. Details of the traffic plan include:

  • Alternate river crossings for all modes include the Hawthorne and Burnside bridges.
  • Ramps between the Morrison Bridge and Interstate 5 and Interstate 84 will be closed, except for the ramp from the Morrison Bridge westbound to I-5 north. 
  • Motorists can access I-84 eastbound at N.E. Grand Avenue and N.E. Everett Street.
  • I-5 north can be accessed from the west side via I-405 north (Fremont Bridge). Eastside access is from the ramp at N.E. Broadway and N. Williams Ave. 
  • To access downtown from I-5 south or I-84 west, I-5 south drivers can exit at the Rose Quarter/Broadway Bridge and I-84 westbound drivers can exit at Rose Quarter/Weidler exits.
  • I-5 south traffic can access the onramp to Highway 99E/U.S. 26. 

Hamilton Construction will finalize the concrete pour from the east pit on the lift span during the closure as other components are upgraded to accommodate the heavier deck. This month, the work will move to the west leaf of the life span. Another bridge closure will be needed in September when concrete is poured for the west leaf deck. 
The contractor expects to complete construction by the end of October 2017. Multnomah County maintains the Morrison Bridge and five other Willamette River bridges. For more information, visit or follow @MultcoBridges on Twitter.
