Knik Arm Bridge

The Knik Arm Bridge is a proposed crossing over Cook Inlet that would link Anchorage with the Matanuska-Susitna Borough to the north. The project would create a direct transportation corridor spanning the water with dedicated traffic lanes in each direction.

Railroad engineers proposed bridging the Knik Arm as early as 1923 to create a route toward Alaska's interior regions. The concept remained under study for many decades before gaining official federal approval in more recent times, though funding obstacles have prevented construction.

The bridge project generated substantial discussion among Anchorage residents, leading to the formation of community groups focused on infrastructure development and environmental preservation.

This is a proposed project rather than an existing structure, so there is currently nothing physical to visit at the site. The Cook Inlet remains crossed only by water travel or by using existing routes around the geography.

The project design included plans for a tunnel beneath Government Hill to address geographical constraints across the inlet. This added engineering complexity meant that costs extended well beyond the bridge span itself.
