Webber Infrastructure Management

Webber Infrastructure Management has operated and maintained the Anton Anderson Memorial Tunnel for the Alaska Department of Transportation and Public Facilities since 2000, the year it opened to vehicular traffic after conversion from a 1943 railroad tunnel. The contract includes traffic control, emergency response, toll collection, and maintenance.

The one-lane tunnel is shared by cars and trains traveling in both directions between the port city of Whittier on Prince William Sound and the Seward Highway. This unique design enables a single lane of traffic to travel directly over the railroad track. Pennsylvania and Washington have dual-use tunnels for light rail and city buses, but not standard automobiles. Non-standard barely begins to describe the longest (2.5 miles) combined rail and highway-use tunnel in North America. It is the first U.S. tunnel with jet turbine and portal fan ventilation, the first tunnel designed for temperatures down to -40 degrees Fahrenheit, and wind speeds up to 150 miles-per-hour.
