The Alaska Department of Transportation and Public Facilities (DOT&PF), in partnership with the Federal Highway Administration (FHWA), is proposing to reconstruct Knik-Goose Bay (KGB) Road between Centaur Avenue and Vine Road in Wasilla and the Matanuska Susitna Borough.
The purpose of this project is to improve mobility for people and freight and to enhance access management along KGB Road between Centaur Avenue and Vine Road. This project will add capacity and correct problems created by unconstrained access, thereby improving safety and reducing congestion for roadway users. It will be designed to accommodate both current needs and future capacity improvements.
The project will expand the corridor to a four-lane divided roadway from Centaur Avenue to Vine Road with a separated multi-use pathway on the north side, four-foot inside shoulders and eight-foot outside shoulders. In order to improve safety and reduce congestion, breaks in the median are proposed for every half mile. Controlled access lines will be added to the plat to prevent median openings spaced less than a half mile. Transition areas will expand the road north of Centaur Avenue and south of Vine Road in order to match the existing roadway. See Figure 1, below.
A Traffic and Safety Analysis will determine intersection improvements. At this time, no additional signals are proposed as part of this project.
