KETCHUM, Idaho – A traffic shift happens today as crews continue to work on the Big Wood River Bridge Project.

Traffic will be diverted onto a portion of the new bridge on Idaho 75, according to the Idaho Transportation Department. Paving the approaching roadway, striping and other details are being completed before the Wednesday morning commute.

Phase two of the $5.5 million bridge project – removal of the existing crossing and construction of the east half of the bridge – is slated to begin immediately after the traffic switch.

Once complete, the new bridge will include four lanes with 8-foot shoulders and a 4-foot median. The project will blend the new bridge lane configuration into the existing five-lane sections north and south of the bridge, according to ITD. In addition to widening, the bridge will be lengthened to improved wildlife passage along the river.

The project is expected to be complete by early summer 2017.
