This Design Study Report (DSR) was prepared in conjunction with Phase II of the West Dowling Road (WDR) extension from the termination of Phase I at C Street, southwest through to Raspberry Road. The objective of this project is to create a new four-lane east to west high speed corridor to relieve traffic from the surrounding major East-West routes. Features of this major objective include constructing a bridge over Arctic Boulevard and the railroad, creating an alignment that will minimize environmental impacts on Tina Lake, and designing channelized intersections with Raspberry Road and Seafood Drive to encourage the flow of traffic. The main goals of the design process were to meet current design standards and to meet the needs of the public through the year 2035. The purpose of this report is to show the engineering thought process and methodology that was applied to meet our desired needs, goals and objectives.
