Downtown Boise Road Work

Fall 2014


New changes are coming to the streets of Downtown Boise this fall. The Ada County Highway District is working to bring transportation improvements to the downtown core. Construction will begin September 2nd and is expected to be complete by the middle of November.

One-way to two-way street conversions:

  • 3rd Street, Main Street to State Street
  • 4th Street,Main Street to State Street
  • 11th Street, Main Street to State Street
  • 12th Street, Front Street to State Street
  • Jefferson Street, 4th Street to 1st Street

Signal changes/additions: As streets transition from one-way to two-way traffic patterns, new traffic signals will need to be installed. This will include adding additional signal poles, mast arms, signal heads, and wiring. Significant changes will also be made to signal equipment in the controller boxes.

  • 3rd Street and Main Street
  • 3rd Street and Idaho Street
  • 11th Street and Main Street
  • 11th Street and Idaho Street
  • 11th Street and Bannock Street
  • 11th Street and Jefferson Street
  • 11th Street and State Street
  • 12th Street and Main Street
  • 12th Street and Idaho Street

Roads to be milled and resurfaced:

  • 12th Street, Front Street to State Street
  • Capital Boulevard, Front Street to Jefferson Street

Some of the work will be done at night to minimize impacts to traffic. Crews could potentially work 7 days a week. No lane closures will be allowed between the hours of 5 a.m. to 9 a.m., and between 4 p.m. to 8 p.m.
