Road Closure: Friday, September 26
On Friday, September 26, a contractor will be working on a utility below the park road near Headquarters. Therefore, the road will be closed to all vehicle traffic at roughly Mile 3. The road will re-open on Saturday morning.
National Park Service Seeking Comments on Environmental Assessment to Rehabilitate Sections of Denali Park Road
Contact: Kris Fister, 907-683-9583
The National Park Service (NPS), in cooperation with the Federal Highway Administration, is proposing to rehabilitate two sections of the Denali Park Road just beyond park headquarters near Mile 4.0 and 4.5. An Environmental Assessment (EA) was written to analyze impacts of the following proposed actions and of a no-action alternative.
The section of road at Mile 4.0 has a chronic soil slump due to a poor road base over melting permafrost. The road would be rerouted to the north for about 1,600 feet through an abandoned borrow pit that would provide a more stable base for the road, and that section of road would then be paved.
The area at Mile 4.5 has hazardous winter ice sheet accumulation due to adjacent springs. This section of road would be raised about three feet, and shifted south approximately five feet. The uphill (north) ditch would be enlarged significantly to hold more winter ice accumulation. Several culverts, each about seven feet in diameter, would be installed to increase drainage, reduce the ice sheeting and facilitate spring road opening.
In both instances the old road bed would be restored by using mats of plant material that would be removed before new road construction, and seeding of native plant species.
The EA is currently available for public review at http://parkplanning.nps.gov. It will also be posted on the Denali National Park Service website at www.nps.gov/dena. Comments on the EA will be accepted through Monday, July 23, 2007. Comments on the project can be submitted by email at http://parkplanning.nps.gov, faxed to (907) 683-9612 or in writing to:

Did You Know?
Recent climate warming has affected Denali in ways that are readily apparent, such as reduced spring snowfall, earlier snowmelt, earlier green-up and thawing of permanent snowfields. Subarctic ecosystems, like Denali, are extremely sensitive to climate variability and change.
