Cascade –The Idaho Transportation Department invites the public to comment on plans to replace the Rainbow Bridge over the North Fork Payette River on State Highway 55.
Community members can participate in an in-person open house from 4 to 7 p.m. tomorrow, at American Legion Post 60 (105 Mill Street) in Cascade. Those unable to attend in person may review materials and provide input online at sh55rainbowbridge.com between July 22 and Aug. 5.
The open house will feature:
-
Updates on the project timeline
-
Design options for the new bridge and retaining walls
-
Information about the condition and history of the existing 1933 bridge
The existing Rainbow Bridge was constructed in 1933 and no longer meets standards for state highway bridges. The new bridge will be located slightly northwest and upstream of the current location. It will include wider lanes and shoulders, and improved sight distance for traffic crossing the bridge. Construction of a new bridge is currently scheduled to begin in 2028.
Initial feedback was gathered during a July 2024 open house. More information is available at sh55rainbowbridge.com. Questions can be directed to the project team at info@55eagletonewmeadows.org or (208) 391-6580.
