About The River

Boise’s enchanting Glenwood Bridge over the Boise River holds quite a rich backstory! It was initially constructed in 1966 as a two-lane bridge, turning into a vital channel for the bustling city’s growing traffic. Excitingly, by 1975 it was expanded to become one of the state’s first five-lane bridges!

  • The architecture used both aesthetic and functional elements based on the Prestressed Concrete Institute’s (PCI) recommendations.
  • Over time, Glenwood Bridge has undergone several renovations to accommodate growing traffic and to maintain the structural integrity of the bridge.

Interestingly, a unique feature of Glenwood Bridge is a miniature park situated beneath the bridge. Known as ‘Eagle Path’, it is a serene spot for residents and visitors to enjoy a quiet moment amidst the city hustle. Without a doubt, Glenwood Bridge surely adds to Boise’s unique charm with both its functional role and its rich history.
