This just in from the Multnomah County Public Affairs Office:
Hawthorne Bridge to close Sunday for maintenance
The Hawthorne Bridge will be closed to road and sidewalk traffic on Sunday, October 26 from 7:00 am until as late as 5:00 pm so that electrical controls for bridge openings can be upgraded. Motor vehicles, pedestrians and bicyclists will not be allowed on the bridge, which will be in the raised position much of the day. The bridge lift span will remain open for river traffic to pass. The work is not weather-dependent.
Alternate river crossings include the Burnside, Morrison, Marquam and Ross Island bridges. TriMet bus lines that normally cross the Hawthorne Bridge will be rerouted across the Morrison Bridge during the closure.
