2040 Transportation Master Plan

MH_PWD_MASTER_PLAN_FNL_20200717

If you’re new to this conversation, in 2020 Arapahoe County began updating the existing Transportation Master Plan with an eye toward 2040. Arapahoe County is the fastest growing county in Colorado and as the population grows, so too does the need for County infrastructure. 

In partnership with local and regional partners, this plan will create a vision for the County’s transportation network—a vision that is critical to minimize congestion, provide quality of life, ensure shorter response times in emergency situations, and guide future growth. It will define improvements, resources and policies that will keep you moving in and through the County for years to come. This community-supported vision is also developed in partnership with our municipal and state partners as the infrastructure within our network is shared and managed by varied agencies.

Phase 2: Public Feedback Survey

The County wrapped up a second outreach phase on March 26, 2021. This consisted of a survey about 24 key corridors. The goal of the survey was to deepen the definition of what's most important to the community to help shape the vision for improvements that will  meet the needs of our growing communities and enhance quality of life. A summary of this outreach will be available later in April 2021. 

What We Learned in Phase 1

We Listened

We spent 2020 listening to you and your ideas about transportation in Arapahoe County. You provided valuable feedback during a virtual public meeting, engaged with a survey, an idea wall and a commenting map. Here's what we learned: 

  • 70% of residents want a focus on roadway modifications to increase safety and manage congestion
  • Residents highly value safe infrastructure that will encourage different mobility options, i.e. bike lanes
  • Residents hope that this feedback helps to provide a more connected, accessible and reliable transit system. Note, the County does not directly provide public transit, but does play a critical role in how residents access public transit and is committed to coordination with transit partners.

We Defined

Defining existing conditions and future land uses is critical to the master planning process. Data defines which roadways are expected to be over capacity and helps to identify priority areas for improvement. View the Existing Conditions Report and Future Conditions Assessment.  

Important highlights:

  • 85% of the County population lives within an incorporated city
  • 65% of employed residents work outside of the County
  • Widespread congestion is currently the highest along Arapahoe Road, Belleview Avenue and Hampden Avenue/I-285 corridors
  • 77 intersections or road segments have been identified for cost-effective safety improvements
  • Drivers and travelers on county roads will notice a 32% increase in total miles traveled by the year 2040
  • The sharpest traffic increases are expected for the area around and east of E-470 including I-70, 6th Avenue, Jewell Avenue, Gun Club Road, and Watkins Road
  • Today, 16.5% of travel is considered “congested.” An increase to 20.4% is expected by 2040
  • Projections forecast the highest levels of congestion will be along 6th Avenue, Hampden Avenue, Belleview Avenue, Arapahoe Road, Santa Fe Drive, University Boulevard., I-25, Havana Street, and Gun Club Road.

This analysis has resulted in the need to get more feedback from the community regarding a list of 24 key transportation corridors. Help us achieve that by taking the Phase 2: Public Feedback Survey.
