Knik-Goose Bay Road: Centaur Ave. to Vine Rd.

What's New:

Construction Phasing Plan

Construction of this project is being split into two phases combined with the adjacent KGB: Vine Road to Settlers Bay Drive project. Construction of the Centaur Avenue to Fairview Loop segment (Phase 1) is anticipated to start in 2022. Construction on the Fairview Loop to Settlers Bay Drive segment (Phase 2) is anticipated to start in 2024. This phasing plan will provide the greatest benefit to the most users, improve the highest volume segment first, and expedite project delivery.

Project Overview

The Alaska Department of Transportation and Public Facilities (DOT&PF), in partnership with the Federal Highway Administration (FHWA), is developing a project to reconstruct Knik-Goose Bay (KGB) Road between Centaur Avenue and Vine Road in Wasilla and the Matanuska-Susitna Borough.

Project Overview Map

The purpose of this project is to increase capacity and improve safety. The corridor currently experiences congestion, poor performance, and high collision rates, particularly during peak hours, due to limited capacity and a high density of driveway access. Congestion issues are only expected to increase, spurred by development along KGB Road, future land development in the Point MacKenzie area, and large anticipated population growth in the Matanuska-Susitna Valley. 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 approximately every half mile to mile. Transition areas will expand the road north of Centaur Avenue and south of Vine Road in order to match the existing roadway.
