Welcome to the website for the Seward Highway
The Alaska Department of Transportation and Public Facilities (DOT&PF), in cooperation with the Federal Highway Administration (FHWA), is rehabilitating approximately 15 miles of the Seward Highway between milepost (MP) 75 near the bottom of Turnagain Pass, and MP 90 near the Girdwood intersection. This project will increase safety, extend the service life of the roadway, replace eight bridges, and repair another bridge (nine bridges in total). Currently, there are no passing lanes along this 15-mile stretch of the highway; both residents and tourists experience heavy congestion, particularly during the peak summer period.
This project includes upgrading the highway by rehabilitating the road, straightening curves in high-accident locations, improving intersections, and allowing for more passing opportunities with the addition of more passing lanes.
Project construction has been divided into two phases, with each phase taking approximately two years to complete construction.

The project area includes the Portage Glacier Road intersection, the Twenty Mile River boat launch area, and the Alaska Railroad Portage Station. As the only land connecting Whittier to communities on the Kenai Peninsula, this portion of the highway receives heavy passenger vehicle, commercial truck, and seasonal tourism industry traffic.
