Broadway Avenue Bridge

Merit Award Winner—Short Span

The Broadway Avenue Bridge connects the communities of Boise by spanning the Boise River with a single-span, parabolic haunch plate girder system. The bridge is the focal point of the greenbelt paths that run along the river through downtown Boise.

“While it's a short-span bridge, the shallow plate girder solution integrates into a total project that serves as a signature bridge for the community,” said Frank Russo, PE, PhD, Michael Baker International, a judge in the competition.
