Welcome to the Seward Highway: 36th Avenue Intersection Improvements project website. The Alaska Department of Transportation and Public Facilities (DOT&PF) is developing preliminary engineering, environmental analysis, and permitting for future improvements at the intersection of 36th Avenue and the Seward Highway.
DOT&PF is currently pursuing alternative funding strategies for this important project. Please visit this site often to stay informed as the project progresses.
The Seward Highway: 36th Avenue Intersection Improvements Project (Seward and 36th Improvements) will redesign the Seward Highway between Tudor Road and approximately 33rd Avenue, and will develop a new interchange at Seward and 36th to reduce congestion and reduce vehicle crashes. The project area, about 1.5 miles in length, is located between 33rd Avenue and Tudor Road. Improvements may include grade separations, highway ramps, frontage roads and project phasing alternatives.
The existing intersection of Seward Highway and 36th Avenue serves many travelers going to and from destinations in Midtown and the U-Med District and is the first stoplight on the Seward Highway when entering Anchorage from the South. The intersection is often congested during rush hour. The Seward and 36th Improvements project will improve traffic flow, reduce travel times, and reduce crash rates.
- Improve traffic flow in Midtown and on the Seward Highway
- Shorten travel times to and from Midtown and U-Med
- Improve safety by reducing crash rates
- Improve safety and travel for bicycles and pedestrians
- Provide consistency with AMATS 2035 MTP
Scope of the Project
In late 2012, the Department of Transportation and Public Facilities (DOT&PF) began preliminary engineering design, public involvement, and environmental analysis for the Seward and 36th Improvements Project. In preliminary engineering design, the project team will develop alternatives for analysis. At a minimum, the alternatives analyzed shall include a no-build alternative (i.e., doing nothing) and a build alternative (i.e., construct improvements). Based on analysis, the DOT&PF selected the Hybrid Single Point Urban Interchange (SPUI) as its preferred alternative. The alternative has been developed to a 30% design level. Future project phases will complete engineering, permitting, and construction.
The Seward Highway: 36th Avenue Intersection Improvements Project is estimated to cost $50-70 million. Cost estimates will be further defined as design progresses and more detail is developed.
