The Alaska Department of Transportation and Public Facilities’ (DOT&PF) Knik-Goose Bay (KGB) Road: Vine Road to Settler’s Bay Drive project proposes to reconstruct KGB Road from Commadore Lane to Settler’s Bay Drive. The objective of this project is to reconstruct the existing two-lane road as a four-lane divided roadway that includes pedestrian facilities, turn pockets, access control, traffic signals, drainage, and other related improvements.
The project design is approximately 75% complete. The project team is reviewing the proposed design based on updated traffic projections to determine if any modifications to the proposed design are needed. The team is also further evaluating drainage issues in the corridor based on public comments regarding ponding in the corridor and erosion issues resulting from concentrated areas of runoff. The team will continue to coordinate with the adjacent KGB Road: Vine Road to Centaur Avenue project to develop an efficient design for the overall KGB corridor that minimizes traffic disruptions during construction. The next steps include completing the hydrology and traffic analyses, refining the engineering plans, continuing to gather public input, working with utility companies to relocate any facilities that are impacted, and initiating the appraisal and acquisition of additional right-of-way that is needed for the project.
The two primary goals of this project are to increase capacity and improve safety. The corridor currently experiences high congestion, low 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 address capacity issues by:
Safety issues will be addressed in this project by considering:
This section of roadway has a mix of industrial, commercial, and residential uses and is identified by DOT&PF as a principal arterial, which means it is intended to provide higher mobility and lower access. In 2009, this roadway was designated by DOT&PF as a Traffic Safety Corridor due to a fatal accident rate that was 3.8 times the national average. There are undeveloped sections of land along this road section and future land development here and to the south will increase use of the road corridor.
Potential right-of-way (ROW) acquisitions, utility conflicts, and ongoing drainage issues have been identified. The project team will develop a State Environmental Checklist, a Design Study Report (DSR), and bid-ready documents (known as Plans, Specifications, and Estimates [PS&E]). See the Schedule and Public Involvment pages for details on the timeline of this project.
