Construction of improvements to Idaho Highway 55 through downtown Marsing has begun. The project will rebuild the Snake River Bridge and repave the highway from the river to the U.S. 95 Junction. When complete, the project will enhance local business opportunities and improve safety and mobility through the area.
Initial work on irrigation lines began Monday, January 14. Major work includes replacing the School Drain pipe and C-Line Canal pipe. Traffic will be reduced to one lane and a temporary signal will direct alternating traffic. Work will be limited to daytime hours, though the lane closure and signal will operate 24/7 for the next 3-4 weeks.
ITD invites the public to an open house to review the final construction plans for this project. The open house will be held Thursday, Jan. 24 from 4 to 7 p.m. at the American Legion Hall in Marsing (126 2nd Ave. W). Attendees will have an opportunity to view construction plans for the new Snake River Bridge and ID-55 improvements, ask questions of project staff, and learn how to stay informed during construction.
“We are encouraging motorists to plan extra time when driving through the areas during construction,” said David Barrett, ITD Project Manager. “We are improving a major route used to haul agricultural products and move people to and through a beautiful part of Southeast Idaho.”
Work to rebuild the bridge will begin in earnest this spring. During construction, one lane of the bridge will be open to traffic with a 14-foot width restriction. The new bridge is expected to be complete by the summer of 2020.
The contractor for this $20.9 million project is Wadsworth Brothers Construction out of Salt Lake City, Utah.

A pavement rehabilitation project between Nampa and Marsing is scheduled to begin July 9 and conclude in late July/early August. Work will seal the pavement and extend the life of the roadway.
The first phase, a six-mile micro-seal from Nampa-Caldwell Boulevard to Farmway Road, will occur in the evening (10 pm – 5 am). Work is expected to conclude the week of July 16.
The second phase, an eight-mile chip-seal from Farmway to the Snake River Bridge at Marsing, will occur during daylight hours. Work is expected to conclude in late July.
During both phases, motorists can expect reduced speeds and up to 15-minute delays as traffic will be periodically reduced to one-lane with a pilot car guiding traffic. Where work is occurring, intersections will be controlled by flaggers with minimal delays. Motorists are encouraged to drive with caution through the work zone.
Schedules are subject to change. The contractor is permitted to work weekends. For up-to-date construction information, visit 511.idaho.gov.
