Update: 4 p.m. Saturday

The Morrison Bridge reopened ahead of schedule after closing Saturday so that parts could be installed in the drawbridge. The ramp from southbound SW Naito Parkway to the bridge also reopened for the first time since the drawbridge repairs began this spring.

All lanes on the bridge and all ramps are now open.

In a string of closures that seem to be never-ending, the Morrison Bridge will be shut down to all forms of traffic, including bikes and pedestrians from 6 a.m. through as late as 6 p.m. Saturday, November 4 as contractors install new parts that support the drawbridge.

According to a recent release, steel parts known as live load shoes support the drawbridge leaves while in the down position. The load shoes can only be replaced while the drawbridge is in the up position.

During the closure, ramps between the Morrison and Interstate 5 and Interstate 84 will be closed, except for the ramp from the bridge westbound to I-5 north.

During the closure, TriMet's bus route 15 will detour and use the Hawthorne Bridge.

The release warns of intermittent off-peak closures of single lanes and sidewalks until November 15 as the contractor finishes up work on the deck replacement. During peak hours, all six traffic lanes and both sidewalks will be available.
