The Morrison Bridge will be closed to all traffic this weekend from 8 p.m. on Friday, October 27 until as late as 5 a.m. on Monday, October 30 while a contractor applies a top overlay coat on the new lift span deck. The epoxy overlay resembles asphalt and provides a smooth ride with good traction.
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.
After this weekend, there will be intermittent closures of single lanes and sidewalks on the Morrison Bridge as the contractor finishes up work on the lift span deck replacement. All six traffic lanes and both sidewalks on the Morrison Bridge will be open by November 1. There will be occasional off-peak single lane closures for a few weeks in November.
