The Knik Arm Bridge is a dormant proposal for a 1.74-mile (2.80 km) bridge across Cook Inlet's Knik Arm to link the two fastest growing parts of Alaska – Anchorage and the Matanuska-Susitna Borough.
The project consists of a 1.74-mile (2.80 km) bridge with 18 miles (29 km) of connector roads, including on and off ramps, and a $50 million cut and cover tunnel under Government Hill. Cost estimates are between $700 and $800 million.
Proponents say the crossing would provide access to much-needed residential, commercial and industrial land; create jobs; reduce the cost of transportation to Interior Alaska and the North Slope; lessen carbon emissions and provide an alternative transportation route out of Anchorage. Opponents, however, say that: the crossing would create unnecessary urban sprawl in the Anchorage area; would be more expensive and less used than projected; would divert limited transportation funding away from more critical projects; would disrupt the Government Hill neighborhood and negatively impact the endangered Cook Inlet beluga whales.
