- U.S. 169/I-70 North Loop PEL Study
Our team worked with the Mid-America Regional Council (MARC), in partnership with the Missouri Department of Transportation and the City of Kansas City, Missouri, to lead the Planning and Environmental Linkages (PEL) study for the U.S. 169/ I-70 North Loop. This $3.5 million project is the first PEL study conducted in the region and provides alternatives for rehabilitating or replacing the aging Broadway Bridge over the Missouri River and accelerate future National Environmental Policy Act (NEPA) activities.
The study also considers major changes to the downtown freeway loop and ways the transportation network can support development and revitalization in the area. Our team was responsible for engaging the community, analyzing ideas and developing a strategic plan for incremental improvements to the transportation infrastructure within the study area. Tasks included:
- Community engagement — Engagement activities were tailored to promote understanding among the project’s diverse stakeholders — residents, businesses and commuters — and connect the planning process to local desires in a positive and proactive way. Activities included visioning and scenario planning, educational materials, charrettes, targeted small-group meetings, and digital outreach.
- Conceptual analysis — The team developed and analyzed a range of conceptual designs that combined possible bridge locations with low-, medium- and high-impact freeway alternatives for the downtown loop, as well as a series of alternatives for the I-70/I-670 loop extending into Kansas City, Kansas.
- Traffic demand modeling — The team developed a Dynameq mesoscopic dynamic traffic assignment (DTA) model of the project area and its surrounding roadway network. This model represents the existing roadway infrastructure, including lane-level details of both freeway and arterial roadway geometrics. It helped the team assess the operational impacts of each alternative and identify improvements for more detailed evaluation in Vissim.
- Environmental review — The study included development of an initial Purpose and Need statement, recommended alternatives to be carried forward into NEPA, identification of key stakeholder concerns, and prioritization of future projects.
The project received a 2019 American Council of Engineering Companies Missouri Engineering Excellence Award.
