The Morrison Bridge will be closed to all traffic on Saturday, November 11 from 7 a.m. until as late as 5 p.m. to allow a contractor to install compression seals on the new lift span deck. The seals allow deck sections to expand and contract with temperature changes. Saturday’s closure should be the last day the bridge is closed due to the lift span deck replacement.
The closure will impact motor vehicles, bicyclists and pedestrians. Details of the traffic plan include:
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 NE Grand Avenue and NE Everett St. or at NE Irving St. and NE 16th Ave.
Access to I-5 north on the eastside is from the ramp at NE Broadway and N Williams Ave.
I-5 south traffic can access the onramp to Highway 99E/U.S. 26.
From downtown, drivers can also access I-5 and I-84 from I-405.
During the closure, TriMet’s bus route 15-Belmont/NW 23rd will detour to the Hawthorne Bridge.
