Matanuska-Susitna Borough

Port MacKenzie

Port MacKenzie is the only port in Alaska that can boast 9,033 acres, 14 square miles dedicated to commercial and industrial development. The docks are designed to efficiently export natural resources as well as many other types of cargoes.

Port MacKenzie, located in Upper Cook Inlet, is a young port with goals for the future including a rail loading facility, fuel tank farm, and promoting the creation of a potential petrochemical facility or LNG plant. 

Our barge dock is 550 feet long and has  -20 feet at low tide. Our deep draft dock accommodates Panamax and Cape Class vessels with -60 feet of water at low tide.

When completed, the Port MacKenzie rail extension will create the shortest rail route from the Interior to tidewater, providing timber and mining industries a faster and less expensive method of export.  The rail loop will be the longest industrial loop in the state for efficient off-loading from railcar to ship.

An almost fifteen acre barge dock coupled with our expansive uplands make Port MacKenzie ideal for large industrial projects and value-added exports.

Port MacKenzie is moving heavy industrial and bulk materials through Alaska and beyond.


Barge Dock

The bulk head has a 14.7 acre gravel surface with a 500 foot sheet pile face for docking barges. The load capacity of the gravel pad is 1,000 pounds per square foot.  A bull rail lines the sheet pile face, tire fenders are used to protect vessels and bollards are available for tie up.  The water depth is -20 feet mean lower low water (MLLW) at the barge dock.  

Deep-Draft Dock

The deep-draft dock extends 1,200 feet into Cook Inlet to a depth of -60 feet at mean lower low water (MLLW) and can accommodate Panamax and Cape Class vessels. The dock is equipped with three-phase power and a five foot wide conveyor system capable of loading bulk commodities at 2,000 tons per hour.

Port MacKenzie Rail Extension

The 32-mile rail link will shorten the distance between the Interior and tidewater, creating the tipping point for the development of new industries with low transportation costs. Already funded $184 million by the Alaska legislature, the project is under construction in segments and needs $125 million to complete. The longest industrial rail loop in the state will provide for efficient movement of materials between ship, rail, truck and barge.

Central Alaska Energy LLC is developing a 4.8 million gallon fuel terminal at Port Mackenzie.  The facility will be capable of storing several grades of product for a variety of commercial customers.  The terminal will have access to multiple fuel sources in Alaska as well as the lower 48 or international supply.  Options for petroleum distribution will include fuel trucks, rail cars, and marine vessels via pipeline to/from the Port MacKenzie Dock.  The new terminal will serve industrial customers requiring physical storage or secure pricing for their petroleum products.


There are plans for a rail line at Port MacKenzie. The Alaska Railroad (ARRC) has teamed with the Matanuska-Susitna Borough (MSB) to design and construct a rail extension from the Parks Highway to Port MacKenzie. The rail extension project is owned and operated by ARRC, and the MSB, as owner of Port MacKenzie, is the project sponsor. The Surface Transportation Board (STB) has approved the Environmental Impact Statement and selected a route to construct a 32.1 mile rail line from the Parks Highway to Port MacKenzie.

More detailed information on the Port MacKenzie Rail Extension project may be found at or on the ARRC’s website. This legacy project will be of great benefit to the entire State of Alaska by providing a shorter distance to tidewater for bulk transport of goods and commodities between Port MacKenzie and Interior Alaska. The rail extension has the potential to open new markets for minerals and stimulate the creation of new Alaskan jobs.

All handling, loading, and unloading services are the responsibility of the shipper, vessel owner, or agent. Completion of the Port MacKenzie Terminal Operator Permit is required for any qualified agent desiring to provide longshore services at the terminal facilities.
