This just in from Multnomah County:
Hawthorne Bridge to close Sunday for inspection
The Hawthorne Bridge will be closed on Sunday, September 7 from 6:00 am until as late as 7:00 pm for an inspection. 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 closure will allow a county crew to inspect critical weight-bearing parts in the bridge towers called sheave trunnions. Sets of sheave trunnions and bearings support the weight of the bridge’s 900-ton lift span and two 450-ton counterweights. The trunnions are inspected every few years to ensure that they are in good condition. The Hawthorne Bridge, which opened in 1910, is the oldest working vertical lift bridge in the country.
Also on Sunday, the outer westbound traffic lane of the Broadway Bridge will be closed and the bridge lift span will be unable to open for river traffic from 8:00 am to 9:00 am during the Pints to Pasta Run.
Alternate river crossings include the Burnside, Morrison, Marquam and Ross Island bridges.
Multnomah County maintains the Hawthorne and Broadway bridges and more than 300 miles of roads and bridges.
