Project Overview x
In the early 2000s, the City of Wasilla and the Knik-Goose Bay (KGB) area experienced rapid population growth. As a result, the City of Wasilla planned to extend South Mack Drive from near the Curtis D. Menard Memorial Sports Complex to South Clapp Street and upgrade the roadway to a major collector. The project was high-priority for both the City of Wasilla and the Matanuska-Susitna Borough (MSB) because it would provide connectivity between the Parks Highway and KGB Road, access to adjacent residential collectors, and provide traffic relief to downtown Wasilla.
HDL assisted the City of Wasilla with the 1.8-mile road extension, which involved constructing 1.3 miles of new roadway, reconstructing 0.5 miles of the existing South Clapp Street, extending South Mack Drive to the newly constructed South Clapp Street, and adding turn lanes at the entrances to the Curtis D. Menard Memorial Sports Complex. Other design features included a new fish passage culvert at Lucille Creek, curbs and gutters, a new pathway approximately 2.15 miles long, traffic control, and signing and striping. HDL also provided right-of-way acquisition services.
During construction, HDL provided construction administration services, performing daily site inspections to document progress material testing.
HDL was concurrently working with the Department of Transportation and Public Facilities (DOT&PF) on the South Clapp Street Realignment and Signalization at KGB Road project to create a new, signalized intersection at KGB Road. HDL worked seamlessly with the DOT&PF, the City of Wasilla, MSB, and local property owners to complete this additional project on schedule and within budget, which allowed this critical signalized intersection to be operational before opening the new South Clapp Street connection to traffic. HDL also performed the construction administration on this project for MSB.
