About the Project
St. Louis City, Missouri
CBB completed this Congestion Mitigation Air Quality Improvement (CMAQ) program project for the City of St. Louis. The Phase 3 work is a continuation of previous work done within the City of St. Louis and focuses to make necessary updates as a result of recent changes to the grid network, including the City+Arch+River project, as well as the new Stan Musial bridge.
The project includes three major components including (1) Downtown Multimodal Study & Signal Timing, (2) Fiber optic network enhancements and (3) Traffic Information Center Operations. The project limits are generally bounded by Jefferson on the west, Cass on the north, Mississippi river on the east, and Chouteau on the south.
The Downtown Multimodal Study developed a robust multimodal system that enhances connections for pedestrians, bicyclists, transit users and motorists, of all ages and abilities, while improving quality of life, supporting economic growth and community development, easing congestion and bettering air quality, and improving public health. The study includes a thorough stakeholder engagement process, as well as traffic counts, and a complete infrastructure inventory to develop updated signal timing plans for Downtown St. Louis.
The plan was completed in June 2018 and adopted by the City’s Planning Commission in December 2018. It provides a framework for the development of future transportation projects in the City of St. Louis. The plan has developed a hierarchy of streets by m ode: walking, biking, transit, and vehicular access. The team has developed recommendations for implementation on these corridors to enhance the travelling experience, improve safety, allow mode choice, promote economic growth, and foster a more vibrant Downtown St. Louis.
In addition to studying the Downtown network and making recommendations for enhanced transportation choices, CBB designed system updates to the downtown network, including ITS devices, cameras, and a more connected fiber network. Strategically placed throughout Downtown, these cameras will assist with enhanced traffic operations. CBB also provided traffic information center staffing, co-located at the Real Time Crime Center in Downtown St. Louis, to monitor operations, and make necessary changes due to any special events or unplanned circumstances.
