Arapahoe Road (SH 88) provides the major east-west travel link from the southeast metropolitan area to employment and retail centers along I-25, including the Denver Tech Center (DTC). Current and projected traffic volumes and increasing traffic congestion along Arapahoe Road between I-25 and Parker Road prompted Arapahoe County to initiate a corridor transportation study to address regional mobility and local accessibility needs now and well into the future.

The majority of funding for the 18 month study was from federal funds, and the remainder was shared among Arapahoe County, Centennial, Greenwood Village and CDOT. The Arapahoe Road Corridor Study explored and defined the most appropriate set of improvements to best move traffic through the Arapahoe Road corridor area, while considering the unique context of this rapidly developing area.

The study included several key elements:

• Defining the immediate and long term transportation needs of the corridor
  
• Considering roadway types and travel mode options that address the corridor needs, considering the principles of Context Sensitive Design
  
• Assessing of the benefits, impacts and tradeoffs of the various transportation improvement options
  
• Identifying a locally preferred, realistic strategy for the timely implementation of the recommended transportation improvements.
