2018 North End Bridge Replacements Project

Construction Update as of 4/12/18:  This project is substantially complete as of 4/05/18.

General Description:

Construction will begin in January 2018 to replace the existing (corroding) metal pipes that cross Breneman Street and Smith Avenue along the Boise City Canal and replace them with new concrete box culverts. The Breneman Street Bridge is located between 25th and 26th streets, and the Smith Avenue Bridge is located between 24th and 26th streets. The new bridge structure will also be extended north and south by about 15 feet from the existing metal pipe. This will allow for the new bridge crossing to extend for the entire width of the right-of-way. 

Local access will be maintained, but Breneman Street and Smith Avenue will be closed for the duration of construction.

Time Frame


Start Date:  January 15, 2018
