The Knik Arm Crossing is a state of Alaska Department of Transportation & Public Facilities (DOT&PF) project to construct a 1.74-mile toll bridge over Cook Inlet’s Knik Arm, connecting Anchorage, Alaska’s largest city, with the Matanuska-Susitna Borough, Alaska’s fastest-growing region.

The Knik Arm Crossing was first envisioned in 1923 by railroad engineers looking for a more direct route to the gold fields in Interior Alaska. Since that time, the idea has been revisited by a variety of people and organizations including a 1972 engineering study by the Alaska Department of Highways and the 1984 Draft Environmental Impact Statement (EIS) by the DOT&PF.

In 2003, the Alaska State Legislature formed a corporation within the DOT&PF and the Knik Arm Bridge & Toll Authority to pursue the development of the bridge. The Authority completed the final EIS in 2007 and the Federal Highway Administration (FHWA) issued a Record of Decision (ROD) in 2010.


The Knik Arm Crossing (KAC) infrastructure project was funded and transferred to DOT&PF in the waning hours of the 2013-’14 Legislative session. Per the Legislation, the project will come to DOT&PF, while KABATA remains as the future tolling authority that will operate the facility. Since the end of April, DOT&PF has been working collaboratively with KAC staff to understand and explore the current project schedule. The DOT&PF is taking this transition time to work methodically and carefully, as we all agree, we do not want to lose the substantial work efforts accomplished to date and the momentum that KABATA has created in reaching the important milestone of authorized funding, bringing reality to this large complex project.

DOT&PF is excited to work directly with DOR, KABATA, FHWA and the existing KAC project staff to efficiently develop this important infrastructure project.
