Operations Strategies Workshop

Plan Overview

The purpose of the I-70 Mountain Corridor Operations Plan is to address recurrent and severe non-recurring congestion in the I-70 corridor between Dotsero and Wadsworth Boulevard, with a particular focus from Copper Mountain to Idaho Springs.

Recognizing the corridor has already deployed an array of operations strategies identified in previous efforts, this plan will be oriented toward articulating new improvements over the next five years that are likely to achieve high benefits relative to costs, and are affordable within known budgetary parameters. The plan will incorporate prioritized solutions that are desirable with corridor stakeholders, and yield a clear implementation plan for phasing and adoption of strategies that fulfill the Programmatic Environmental Impact Statement (PEIS) recommendations.

Operational improvements to address congestion may include elements of:

  • highway infrastructure improvements;
  • additional Active Traffic Management systems;
  • managed lanes;
  • Intelligent Transportation Systems (ITS) infrastructure;
  • improved maintenance techniques;
  • work zone management;
  • better management of traffic flow during adverse weather or special events;
  • improvements for freight transporters;
  • improved traffic incident management and clearance times;
  • improved public information; and
  • preparation for connected and/or automated vehicle technologies.

Operations Strategies Workshop Overview

The workshops will each include two parts:

  1. A study overview for corridor stakeholders, which will:
    • cover study goals and objectives, and the purpose of the workshop;
    • define an operational improvement;
    • introduce subject matter experts and the operational strategy inventory process; and
    • facilitate stakeholder input on the focus of the second session.
  2. The second part will be more technical in nature, and will include:
    • a review of existing traffic conditions;
    • recommended operational strategies; and
    • best practice strategies from subject matter experts.
    The second session will also include interactive activities to identify and prioritize operational strategies.

The primary outcome of the workshop will be to identify appropriate measures of effectiveness and potential viable strategies to be carried forward for further evaluation.

The workshop will be conducted over the course of two consecutive days, with one at CDOT's Trail Ridge Conference Room (425 Corporate Circle, Golden, CO 80401), and the other occurring at the Silverthorne Town Hall Council Chambers, 601 Center Circle, Silverthorne, CO 80498.


Invited participants include CDOT, the Federal Highway Administration (FHWA), county, municipality, Colorado State Patrol, Colorado Motor Carriers Association (CMCA), and key corridor stakeholders involved with the delivery of operations strategies on I-70.


The workshop will be facilitated by Andy Mountain (GBSM) and (Les Jacobson (WSP|PB). Les is the current committee chair of the TRB Regional TSM&O Committee, and WSP|PB's international director for TSM&O activities.

Other project team participants include:

  • topical experts David Ungemah (managed lanes, TDM, pricing topics);
  • Les Jacobson (flow metering, ATM, shoulder utilization);
  • Diego Carroll (managed lanes, ITS, lane control systems, arterial systems); and
  • Scott Shogan (traffic management, modeling, connected / automated vehicles);
  • as well as ITS experts Scott Thomas and Ken DePinto of Apex Design.
