There will be temporary closures on Idaho Highway 55 at the Snake River Bridge in Marsing while girders are placed for the new bridge.
Girders are large horizontal beams that support the surface of the bridge. Each girder weighs 141,000 pounds and is 148 feet long. Current plans call for girders to be placed overnight on Tuesday Sept. 3, Thursday Sept. 5, Friday Sept. 13, and Monday Sept. 16. This is subject to change.
Sunny Slope Rd. southbound will be reduced to one lane between Lowell and True road. The lanes will be restricted from noon to 2:00 am each night to stage the bridge girders. Placement of the girders will generally occur between the hours of 10:00 pm and 2:00 am. Traffic will be stopped for up to thirty minutes while each girder is placed. Each night up to three girders will be placed.
This work is part of a two year-long project to replace the Snake River Bridge in Marsing The project will improve safety and driving conditions on the bridge, which is the primary river crossing for the area. More information can be found at https://itdprojects.org/marsing55improvements/.
