UPRR Gladstone Emergency Repair
Start Date: September 2013
End Date: May 2014
At the request of the Union Pacific Railroad, Hamilton Construction led the emergency response when it was discovered an aging railroad bridge, long out of service, was in immediate danger of toppling over into Oregon's Clackamas River. Upon inspection of the bridge's cracking foundation, the situation was deemed too unsafe for crews to repair. The area was immediately secured, including stopping river traffic underneath. Then Hamilton, working closely with UPRR, law enforcement, regulatory agencies and a team of subcontractors devised a method of dropping the bridge and pulling it out the river with a heavy winch system. With high power lines on one side of the bridge and a water processing facility on the other, Hamilton's scheme to drop the bridge straight down was critical to the successful outcome of the situation. The bridge drop occurred precisely as planned. The bridge was demolished as it was pulled out the river, cut into sections and removed.
