Project Overviewx

One of HDL’s major transportation projects was the Glenn Highway Reconstruction, MP 34-42 Parks Highway to Old Glenn Highway project for the Department of Transportation and Public Facilities (DOT&PF). With HDL’s expertise, the project delivered necessary improvements to this section of roadway that increased safety, capacity, and accessibility.

The corridor extends through residential and commercial properties, with Alaska Railroad Corporation and City of Palmer properties located on either side of the highway. HDL analyzed multiple alternatives, including frontage roads and additional side streets to the corridor to help accommodate the project traffic levels. HDL worked to ensure these alternatives balanced the future needs of the roadway facilities with the needs of the corridor stakeholders.

Initially, the project was controversial with stakeholders. Residents along the corridor were concerned about losing small-town values in Palmer and the increased traffic near their homes. However, the Transportation Group developed designs that minimized overall disturbances to the surrounding area. Through thoughtful design work and careful public involvement efforts, the HDL team garnered public support and overcame any controversial right-of-way acquisitions.

The project’s scope involved widening the existing two-lane highway into a four-lane divided highway with partial frontage roads and pedestrian pathways. HDL provided site evaluations, civil design, a Design Study Report, traffic and safety analysis, utility coordination, preparation of plans, specification and estimate, public involvement, environmental analysis for an Environmental Assessment re-evaluation, wetlands reconnaissance, noise analysis, a historic resources survey, Section 106 Consultation, Section 4(f), and permits.

The first phase of the project began in 2018 and involved clearing brush, grubbing, removing structures, and utility reconfiguration. In 2019, new lanes were paved, four new traffic signals were put in, and a frontage road from Glacier View Avenue to Cienna Avenue was put in.

HDL received minimal change orders during the first phase of construction. The design utilized existing material throughout to reduce overall costs for DOT&PF. Ultimately, the project built up the surrounding communities, increased traffic mobility, and ended with an aesthetically pleasing corridor.
