Downtown St. Louis - Transportation Study

Project Intro/Overview


The Downtown Multimodal Study is one component of a three part Congestion Mitigation Air Quality (CMAQ Grant) project of the City of St. Louis. The project also includes Traffic Information Center Staffing, as well as a System Buildout. The Downtown Multimodal Study component includes a signal timing plan, developing recommendations for a robust multimodal transportation network, as well as a Protected Bike Network Plan.

The Downtown Multimodal Study (and larger CMAQ project) began in February 2017. The purpose of the Downtown Multimodal Study is to develop a robust multimodal transportation plan for Downtown St. Louis, that can be used to leverage potential future federal funding and implement transportation projects. The project came to fruition after many changes to the Downtown street grid initiated the need to look at how traffic flows, as well as how other modes connect to, from and within Downtown. The New Mississippi River Bridge (Stan Musial Veterans Memorial Bridge) opened in 2014, which altered interstate access to Downtown. Additionally, the City+Arch+River project connected the Downtown core to the Arch Grounds. Those two major projects, coupled with the growing interest in bike commuting in St. Louis, as well as the desire to enhance the pedestrian experience and encourage transit, resulted in the incorporation of the Downtown Multimodal Study with this City of St. Louis CMAQ project. Finally, completing this study in conjunction with network design, and Traffic Information Center staffing, offer the team a unique ability to be sure elements included within the plan, are workable in the field for future implementation.

Timeline – Where We Are At

Project Limits

The Downtown Multimodal Study limits are Jefferson on the west, Cass on the north, the Mississippi River on the east and Chouteau on the south. While our team is focusing on planning efforts within those limits, we understand the importance of connections to nearby neighborhoods, as well as other destinations, attractions, employment centers and educational areas within the City. We are coordinating closely with many planning efforts currently taking place to assist with developing a plan that enhances connections and increases access to opportunity for the residents and visitors to the City of St. Louis.

Who Has Been Involved (Week One Overview)

The Downtown Multimodal Study is being led by CBB Transportation Engineers + Planners as the prime consultant, with Alta Planning + Design on the team to assist with developing the bike plan for Downtown. The project is being coordinated with the City of St. Louis Board of Public Service (BPS) and the Street Department.

In April 2017, the core study team (City of St. Louis BPS, Street Department, CBB & Alta) met with 19 pre-identified stakeholder groups to gather information on existing conditions, as well as coordinate with many current planning efforts. Approximately 75 attendees joined us for focus group discussions about topics that emerged as a priority for this study, as well as important components to the Downtown transportation system.

During this week we discussed the project vision and various multimodal plan elements. We gained a wealth of information on current challenges and opportunities in Downtown St. Louis, as well as got feedback on priorities. From this week, the team developed project goals and objectives. These goals and objectives describe areas of importance, and are supplemented with measurable strategies and elements for potential future implementation.

Also at this week, we got a clearer picture of missing connections, and how to better make Downtown a more walkable community. We developed a hierarchy of streets that prioritizes different modes on different corridors. By doing this, future projects can focus on areas to make streets very walkable, bikable and transit friendly. We also utilized the information from this week to develop a thorough infrastructure inventory list that has been completed within the project limits for Downtown St. Louis. Emerging themes from the week are included in the word bubble below.
