KETCHUM, Idaho (News Release) – Crews resume work on the Big Wood River Bridge after a three-month winter shutdown.
Work begins by completing the eight concrete girders on the east side of the bridge.
The bridge will be reduced to a single lane beginning Thursday night during the operation. The contractor will also have flaggers at the intersection of Idaho 75 and Serenade, where trucks carrying the girders will turn around.
The girders will be placed beginning at 9 p.m. Thursday and should be complete before the morning commute Friday.
Construction of the new bridge began in January 2016 with the southbound lanes of the bridge, which was completed last summer. The bridge project is expected to be finished by August.
Traffic will remain limited to two lanes – one lane in each direction – for the remainder of the project. Traffic speeds will remain at 35 mph through the construction zone and drivers are reminded to use caution merging into the single lane from each direction.
Earlier this week, crews were busy exposing bridge piers installed last fall. The girders are to be set first so the crane pad can be removed before high water in the river channel later this spring. Remaining work includes placement of abutments, wildlife passage, bridge deck, and adjacent roadway for the northbound lanes of the structure.
When complete, the new Big Wood River bridge will facilitate four lanes of traffic with eight-foot shoulders and a four-foot median. In addition to being wider, the new bridge also is longer to facilitate additional wildlife passage along the river.
Concrete Placing Company Inc., of Boise, is the contractor for the $5.48 million bridge replacement.
