Mobility and Accessibility
Mobility and accessibility must address local, regional, and national travel by providing reliability, efficiency, and the interconnectivity between systems and communities.
Mobility and accessibility on the corridor are served by promoting and providing options that best fit a variety of travel and access needs. Remain open to and consider new approaches and technology that advance mobility and accessibility.
The I-70 Mountain Corridor is an important part of our national interstate system and a vital route for the travelers and truckers who cross our nation. It provides access for Coloradoans statewide who wish to access the Rocky Mountains and the national forests, ski areas, and recreation areas in the corridor. The I-70 Mountain Corridor provides critical links to and between the communities along the corridor. An unprecedented number of vehicles travel through the Eisenhower/Johnson Memorial Tunnels, and the corridor is frequently congested. Because many travelers and communities depend on I-70, mobility and accessibility must be considered with any improvements in the I‑70 Mountain Corridor.
The Evaluation Guidance details how I-70 Mountain Corridor alternatives will be evaluated. The Alternative Evaluation Guidance documents how mobility and accessibility criteria will be used to determine how well an alternative is able to address local, regional, and national travel while providing a reliable and efficient transportation system that is interconnected with communities. Criteria are provided for use at each level of alternative analysis.
CDOT recently completed a design speed study for the corridor that recommends design speeds for future projects. As part of this study, CDOT also completed guidance for the use of variable speed limits in the corridor to improve traffic flow and mobility.
During the I-70 Mountain Corridor Context Sensitive Solution Workshops, the stakeholders developed a list of critical issuesto be considered during all future work on the corridor. The stakeholders further provided a list of mobility and accessibility strategies that should be considered when developing and refining alternatives.
