Matanuska-Susitna Borough's stated purpose is to provide a new connection between the Parks Highway and Nelson Road that would accommodate recent and projected development in the area south of Parks Highway and west of Glenn Highway. The proposed project would construct a 1.1 mile extension of Trunk Road from the south side of the Parks Highway to Nelson Road, and would rebuild Nelson Road west to the Wasilla Creek Bridge, which would be replaced with a wider bridge. Up to 282,465 cubic yards of various types of fill material would be placed within 7.38 acres of waters of the U.S., including wetlands. The total length of the project would be 1.5 miles and would include a new bridge over the Alaska Railroad (AKRR). The new Trunk Road would include two 12-foot lanes with shoulders between five and eight feet wide and 4:1 to 6:1 horizontal to vertical side slopes. A 10-foot asphalt pathway would be located on the west side of the road and would be separated from the road by five feet. The bridge over the AKRR would be a new bridge 170 feet long and 54 feet wide and made of precast prestressed concrete segments with a cast in place concrete deck roadway surface. The existing bridge over Wasilla Creek is 40 feet long and 26 feet wide, and would be replaced with a bridge 110 feet long and 54 feet wide to accommodate a 100-year flood. Both the existing and proposed bridges are wider than the ordinary high water (OHW) width of Wasilla Creek, which is 18 feet wide. This new bridge would also be made of precast prestressed concrete segments with an asphalt concrete roadway surface. The new road would be designated as a Collector road and would have a speed limit of 40 mph north of the AKRR crossing and 35 mph south of the crossing.
