The Broadway Bridge over the Boise River was first built in 1891 and replaced in 1956. The project will look at widening the bridge to better accommodate the cars, pedestrians and bicyclists that travel over the structure, particularly during local community events. In addition, inspections have identified small cracks and signs of wear on the bridge.

The cost to design, engineer and replace the bridge will be approximately US$16 million. The finished bridge will have a 75-year design life.

Construction is due to begin in late 2014.
