Transportation Committee Receives Update on Broadway Bridge Replacement Project

The Idaho Transportation Department (ITD) is currently planning for the replacement of the Broadway Avenue Bridge over the Boise River. The bridge, originally built in 1892 and replaced once in 1956, is too narrow for the 24,500 cars that travel across the bridge daily, in addition to pedestrians and bicyclists. The project will include removing and rebuilding the bridge, widening and repaving Broadway Avenue between University Drive and Myrtle Street, repaving Broadway Avenue between Myrtle Street and Front Street, improving the Greenbelt pathway near the bridge, and improving traffic flow and pedestrian/bicycle safety on Broadway between University Drive and Front Street.

This project is still in the early stages of design and public input is important. ITD is committed to working with the community to design the new bridge and rebuild it with minimal impacts to the public. ITD has partnered with the Chamber on their public outreach efforts and to help minimize the impact to business resulting from a partial or full closure of the bridge during construction. The Boise Chamber of Commerce’s Transportation Committee met the morning of Wednesday, June 18th to hear an update from Mark Campbell, Project Manager at the Idaho Transportation Department, regarding the potential design of the bridge. Additionally, Campbell shared that preliminary pile-driving testing showed no physical impact to Christ Chapel at the southeast corner of the bridge.

Construction is slated to begin in late 2015 and could be completed in 2016 or 2017. The new bridge will have a 75-year design life to meet current and future community demands.
