From east to west

摘要

As part of a major multi-phased, multi-modal project to improve east-west connectivity across Anchorage, Alaska, the West Dowling Road structure over the new Howard Holton Drive was proposed. During the design process, it was determined the new alignment of the West Dowling Road Extension would require large fills of over 40 ft to match the grade of the required bridge over the Alaska Railroad and Arctic Boulevard. These fills would separate the industrial park on the west of the project from the major arterial of Arctic Boulevard to the east of the project. The structure would avoid leading traffic on a circuitous route to an arterial a mile to the north and ensure that local businesses still had access to the area. Additionally, the project would improve the bicycle and pedestrian facilities in the area, providing access to nearby trails.
