In 2004, transportation officials discovered cracks forming on Portland, Oregon's 87 year old Sellwood bridge. Closing the crossing entirely while building a new one would divert too much traffic to other bridges, so why not simply move the bridge? Well that's exactly what happened last weekend as construction crews moved the 1,100 foot long bridge 33 feet on the east side and 66 feet on the west side. Once the new bridge is completed, the old will be used as a crossing for pedestrians and bicyclists. See the impressive time lapse video below.
