Oregon Map of Hamilton project

Broadway Bridge / Portland Streetcar

Portland, Oregon

Start Date: March 2010
End Date: March 2011

The Broadway Bridge is at the heart of Portland's urban core and a commuter crossroad for motorists, pedestrians, boaters, and more than 8,000 bicycles a day. Hamilton's work on this project included a complete retrofit of the 100-year old bridge including removal of turn-of-the-century streetcar tracks, substructural steel retrofit, mechanical work on the bridge's bascule spans, replacement of the bridge deck with fiber reinforced polymer (FRP) deck panels, installation of new streetcar tracks, sidewalk replacement, concrete overlay, and painting. The high point of the project was the team's success in completing a complicated and demanding work schedule on the bascule span of the bridge during a 60-day bridge closure – which involved staging work so the 100-year-old Willamette River bridge could be lifted every four days to let ships pass through to an upriver grain elevator.
