Portland's Morrison Bridge closed Sunday morning and will remain blocked off until as late as 5 p.m. to allow crews to conduct inspections of the problematic lift-span deck.



Sidewalks will remain open for bicyclists and pedestrians. But the on- and off-ramps from the bridge to Interstates 5 and 84 will be closed.



During the closure, TriMet's 15-Belmont line will use the Burnside Bridge in both directions. Motorists can access I-5 north at Northeast Broadway and North Williams Avenue and enter I-84 eastbound at Northeast Grand Avenue and Everett Street.



Multnomah County recently announced plans to spend $7.3 million to tear up the slip-resistant polymer panels they spent $4.2 million to install on the Morrison just 27 months ago because they are breaking down.
