Parks Highway MP 163-305 Passing Lanes

Updated November, 30, 2011

The Alaska Department of Transportation and Public Facilities (ADOT&PF), in cooperation with the Alaska Division of the Federal Highway Administration (FHWA), is proposing to construct passing lanes at various locations between mileposts (MP) 163 and 305 on the Parks Highway. Following the public and agency scoping period and further design effort by the ADOT&PF, the passing lane locations have been revised.

The following table summarizes the passing lane locations to be evaluated in the environmental document and provides responses to comments and concerns raised by the public, local government, and agencies following the scoping period.

Milepost Range Direction Resolution to Comments & Discussion of Revisions
298 to 296 Southbound No location specific comments received. The northbound direction was deleted from this passing lane segment to minimize impacts to residential approaches.
296 to 294 Northbound No location specific comments received. The southbound direction was deleted from this passing lane segment to minimize wetland impacts and impacts to residential approaches.
291.5 to 289.5 Northbound & Southbound No location specific comments received. The passing lane extents were adjusted by 0.5 miles at either end to minimize impacts to residential approaches.
274.5 to 272.5 Northbound & Southbound The northern extent of the passing lanes was adjusted to 1700-ft south of the sharp curve approaching the Rex bridge and 5800-ft south of the bridge itself.
267 to 265 Southbound The northbound passing lane was deleted to address safety concerns regarding poor roadway geometrics at MP 266.3 for the northbound lane.
234.7 to 232.5 Northbound & Southbound The northern extent of the passing lanes was adjusted to 0.25 miles south of the railroad crossing to minimize wetland involvement and address safety concerns relating to termination at a railroad crossing.
215 to 213 Northbound The southbound passing lane was deleted due to public comment. The northern extent of the passing lane was adjusted to 0.5 miles south of the Nenana River bridge to address safety concerns regarding the curve at the bridge.
200 to 198 Northbound & Southbound No location specific comments received.
180 to 178 Northbound No location specific comments received.
172 to 170 Northbound & Southbound No location specific comments received.
168.4 to 166.1 Northbound & Southbound No location specific comments received. The passing lane extents were adjusted to avoid beginning and ending the passing lanes in the middle of a curve.

The following passing lane locations have been deleted for a variety of reasons, including roadway geometrics, public and local government opposition, and proximity to more desirable passing lane locations:

  • MP 272 to 270
  • MP 229 to 227
  • MP 221.5 to 219
  • MP 183 to 181

The Department continues to develop the environmental document. This website will continue to be updated as the project develops so please check back often.
