Kenai Peninsula Highway Costs Rise in Alaska’s 2027-30 Transportation Plan

Sterling and Soldotna Safety Corridor Costs Rise

A substantial cost revision on the Kenai Peninsula affects the highway safety corridor stretching between Sterling and Soldotna. A pending amendment to the current 2024–27 STIP increases the project budget by 112%, lifting expenditures from $62.5 million to $132.53 million for the stretch between mileposts 82.5 and 90. Across all developmental stages, that same pending amendment pushes the combined price tag for the 11.5-mile corridor to roughly $277.9 million, according to state transportation records. Of that total, $126.5 million is scheduled after fiscal year 2027 to fund the final phase between mileposts 90 and 94. The broad infrastructure undertaking aims to widen the existing two-lane highway to four lanes, incorporate dedicated turn lanes, and build separate bicycle and pedestrian facilities. Early clearing along the route concluded in April, and the Alaska Department of Transportation indicates that major construction activity will resume in spring 2027.

Cooper Landing Realignment Secures Capital Funding

Farther east along the highway network, Stage 4 of the milepost 45–60 project near Cooper Landing has secured significant financial backing through Alaska’s enacted fiscal year 2027 capital budget. The budget allocates $135.1 million in federal receipts specifically for this phase. The reconstruction initiative realigns approximately 10 miles of highway and reconstructs another five miles. Key components of this engineering effort include the Juneau Creek bridge, wildlife and pedestrian crossings, new trailheads, and dedicated passing and climbing lanes.

Seward Highway and Lower Peninsula Upgrades Scheduled

Additional major corridor work extends deep into the new 2027–30 STIP timeline. The current draft identifies $78.2 million in expenditures following fiscal year 2027 to rehabilitate the Seward Highway from Trail River to the Sterling Wye near Moose Pass, with construction slated between 2028 and 2030. That project incorporates passing lanes, pedestrian pathways, drainage upgrades, utility, and general roadside improvements.

In the southern region of the peninsula, capital spending targets several projects. The enacted state budget directs roughly $3.31 million in federal funding toward Stage 1 of the Sterling Highway reconstruction between Anchor Point and Baycrest Hill, alongside $6.14 million dedicated to a separate highway safety stage on the same route. Meanwhile, a 12-mile project along Kalifornsky Beach Road advances with highway widening, passing lanes, and improved drainage. Municipal efforts in Homer focus on filling gaps in the local non-motorized travel network by constructing roughly 4,950 feet of new sidewalk and upgraded crossings. Work along Kachemak Bay Drive is engineered to raise and widen 3.5 miles of roadway serving as a designated tsunami evacuation route between the Sterling Highway and East End Road.

Nikiski Highway Reroute Linked to LNG Development

State spending plans also account for industrial expansion in the northern peninsula. Fiscal year 2027 funding allocates $1.82 million for a Kenai Spur Highway reroute in Nikiski, a project directly tied to the proposed Alaska LNG development. State budget documents outline plans for a new two-lane highway alignment featuring intersections and safety enhancements around the proposed facility site. Transportation officials note that the existing highway route runs across the proposed industrial footprint, making a reroute necessary if the LNG initiative moves forward.
