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

What's New:

Phase 1 - Fairview Loop to Centaur Avenue is now under construction.

Construction updates can be found at Alaska 511, the Alaska Project Exchange Mapper (APEX), or call the project hotline (907) 373-0061

Construction Phasing Plan

The segment from Centaur Avenue to Fairview Loop (Phase 1) is currently under construction. Construction on the Fairview Loop to Settlers Bay Drive segment (Phase 2) is anticipated to start in 2027. 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 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.

New Traffic Pattern at the Palmer-Wasilla Highway and Knik-Goose Bay Road Intersection

Crews have been busy at work this summer reconstructing the intersection of the Palmer-Wasilla Highway and KGB. There are a few big changes at the new intersection, which will be fully operational by Wednesday, September 25, 2024.

Here's what's new:

  • There is a new dedicated right-hand turn lane for northbound KGB traffic (headed toward the Parks Highway) that's turning right onto the Palmer-Wasilla Highway.
  • There will be a new signal at the crosswalk across the dedicated right turn. Pedestrians can activate the signal when they need to use the crosswalk to stop the right-turning traffic.
  • For traffic heading westbound on the Palmer-Wasilla Highway toward KGB, there will be one right-turn only lane, two left-turn only lanes, and one through lane.

Here's what this means for vehicles:

  • If you are turning right from KGB onto the Palmer-Wasilla Highway you will use the dedicated right-hand turn lane.
  • When driving in the new dedicated right-hand turn lane, you MUST STOP FOR PEDESTRIANS if the red arrow turn signal is activated, which indicates there is a pedestrian in the crosswalk. Remember, it is Alaska state law that drivers must ALWAYS YIELD for pedestrians in crosswalks (even if the red signal isn't activated).
  • If you are driving west on the Palmer-Wasilla Highway the right lane is now a RIGHT TURN ONLY lane. If you want to continue straight through the intersection to Riley Avenue you will need to be in the next lane over.

Here's what this means for pedestrians:

There is a new crosswalk just for crossing the dedicated right-hand turn lane. There will be a button for you to press that will activate a red signal that lets drivers know they must stop and allow you to cross.
