The anchor strut replacement and operating strut rehabilitation on the Broadway Bridge represent the latest in a series of projects to upgrade the northern most bridge over the Willamette River.
The Broadway Bridge was constructed in 1911 & 1912. The bridge currently carries four lanes of traffic with an average daily volume of 30,000 vehicles.
The Broadway Bridge had a long list of repair needs, which began to be addressed in 2003.
Multnomah County has completed work to replace portions of the sidewalk on the NW Broadway ramp to the bridge & install new lights across the bridge to improve efficiency & reduce maintenance & costs.
This project replaced worn mechanical components within the bridge's East Machinery House such as shaft bearings, gears and motor components important to opening and closing the lift spans.
This 1926 structure is located on one of the longest and busiest streets in the Portland area. The five-lane bridge and namesake street link downtown Portland to points east and west.
Work has been completed on Multnomah County's project to rehabilitate the deck of the Burnside Bridge and install a system of seismic restraints.
A two-year construction project on the Burnside Bridge has completed its final stage. The $9 million project has completed critical repairs to the lift span of the historic bridge.
The Morrison Bridge is an example of a Chicago-type bascule bridge.
Early bridges were constructed of timber and stone because those materials were readily available.

Maintenance crews completed upgrades to two bent caps under the Hawthorne Street Ramp of the Hawthorne Bridge and one bent cap under the Morrison A Avenue Ramp of the Morrison Bridge.
The 1,383-foot long Hawthorne Bridge is one of Portland’s busiest bridges, safely carrying approximately 30,000 vehicles and untold pedestrians and cyclists across the Willamette River.
Spanning 13 months from March 1998 to April 1999, the Hawthorne Bridge Painting and Deck Replacement Project was one of the longest and most comprehensive overhauls for the historic Hawthorne Bridge.

Work has begun on this $1.024 million project to upgrade electrical service and controls for the Morrison and Burnside bridges.
Sleek in design—"minimalist architecture," some say—the Morrison Bridge marked the advent of freeways and faster cars in the Portland area.
The project has installed permanent improvements to ease access across the south side of the bridge.
The east ramps of the Morrison Bridge, which connect downtown Portland with the inner east side, Interstate 5 and Interstate 84, are getting a new concrete overlay in 2001.
Movable bridges are used where the roadway would otherwise obstruct a navigable waterway and impede river traffic.
