Project Description

Trunk Road Extension South

Matanuska-Susitna Borough, Alaska

Start Date: May 2016
End Date: October 2016


This project extended Trunk Road southward from the Parks Highway to Nelson Road to respond to a growing community by providing improved access to the area south of the Parks Highway and east of Fairview Loop, as well as to develop an integrated roadway network that respects neighborhoods, minimizes through-traffic, and facilitates better pedestrian and vehicular movement.

The new 1.5-mile road segment includes a multi-leg roundabout to be constructed on the south side of the Parks Highway Interchange, a roadway to the south with 12-foot travel lanes, and paved shoulders. Our team built a new bridge crossing the railroad and replaced the existing bridge at Wasilla Creek.
