Anton Anderson Memorial Tunnel is the longest (2.5 miles) highway tunnel in North America, and the first designed for -40 Fahrenheit temperatures and 150 mph winds! The one-lane tunnel must be shared by cars and trains traveling in both directions, and it usually needs to be aired out in between trips (with jet turbine ventilation, another first!). This unique design that enables a single lane of traffic to travel directly over the railroad track saved tens of millions of dollars over the cost of constructing a new tunnel.

Potter Marsh, at the southern end of the Anchorage Coastal Wildlife Refuge, is an ideal break from Anchorage for birders and other wildlife viewers. From the Seward Highway just before the left turn into the Potter Marsh parking lot, you are treated to a stunning view of Turnagain Arm. A wooden boardwalk winds 1,550 feet from the parking area through the marsh and across watery openings and sedges, perfect habitat for a rich variety of birds. From late April through September, Canada geese, northern pintails, canvasback ducks, red-necked phalaropes, horned and red-necked grebes, and northern harriers use this wetland. Look for eagle nests in the cottonwoods near the base of the bluff using binoculars or a spotting scope.
