Great Western/Glassford Hill Extension StudyGreat Western Corridor Study

Project History• Central Yavapai Metropolitan Planning Organization (CYMPO)

– Based on previous studies dating back to 1995 and the 2006 CYMPO study, a need for a new high capacity access controlled roadway was identified to meet year 2030 traffic demands.

• Arizona Department of Transportation (ADOT)– Transportation Investment Strategy identified the need for Great

Western/Glassford Hill Corridor to meet future traffic demands.

• Yavapai County– Taking the lead to further study the Great Western Corridor for a future

controlled access roadway.

Project Overview• Need for a regional system as identified by CYMPO, Yavapai

County, and ADOT • Continual coordination with agencies, community, and

stakeholders• Define the future controlled access roadway needed to efficiently

move regional traffic• Evaluate the environmental impacts of the preferred roadway

corridor• Prepare Feasibility Study and 15% design plans to identify future

right-of-way requirements• No construction funding
