PORTLAND, Ore. -- The Oregon Department of Transportation disrupted traffic on the Interstate Bridge to fit and replace part of the mechanism that controls the drawbridge.
Crews are working to replace a 300-pound roller that broke Nov. 22.
ODOT spokesman Don Hamilton said the lift on the bridge was only at half its regular speed on the southbound span. The new roller will speed up the lifts.
Crews had to take the roller out after they found problems with it, Hamilton said. It will be installed in one week.
Southbound lanes were closed for about 20 minutes at a time for bridge lifts during construction.
