Rebuild Bannock Street
12th to 16th Street

Streetscape and intersection updates to improve pedestrian and bike connectivity from the West Downtown Neighborhood into downtown Boise.

Construction Updates:

Starting in April, Capital City Development Corporation (CCDC) will begin the final phases of the Rebuild Bannock Street project, completing improvements between 12th Street and 13th Street.

Construction will begin on Monday, April 13, and the upcoming closures include a lane reduction and sidewalk closure on the west side of 13th Street as well as a full road and sidewalk closure on Bannock Street.

Rebuild Bannock Street reflects extensive community and stakeholder input. Earlier phases of the project delivered key improvements, including:

Adding traffic signals at the Bannock Street intersections of 15th Street and 16th Street.
Rebuilding sidewalks, pedestrian ramps, driveway approaches and adding street trees.
Repaving the road and upgrading the aging underground canal crossing beneath Bannock Street to ensure future irrigation flow.

Vehicle Updates:

The west lane closure on 13^th Street will block parking lot access to the Saint Paul Baptist Church from 13^th Street. Access to the parking lot can be made via Bannock Street during this closure.
Starting Wednesday, April 15, Bannock Street between 12th Street and 13th Street will be closed. Parking access to Idaho Film Society and the Idaho Power parking lot south of Bannock Street can be made via 12th Street.

About the Project:
