St. Louis Multi-Modal Transportation Planning Initiatives
Hosted by: CBB Transportation Engineers and Planners
Agencies throughout St. Louis are actively engaged in enhancing the region’s multimodal transportation system to create better infrastructure and connections for pedestrians, bicyclists, transit users and motorists, of all ages and abilities. These improvements will ultimately create a safer transportation system, improve quality of life, support economic growth and community development, ease congestion, and improve public health. This session will explore a few of the region’s recent projects aimed at that goal.
In recent years, many communities in the United States have renewed their focus on making streets safer for all users. Residents, visitors, workers, business owners, tourists, and decision makers alike are recognizing the need to calm traffic and create a more welcoming environment for all transportation users. However, this renewed focus does not define the beginning of this practice. Traffic calming techniques have been used in the United States and in other countries since the 1970’s. With the recent focus on making streets safer for all users, there is a heightened need for greater consistency in the application of traffic calming treatments throughout the City of St. Louis. A data-driven approach guiding where and how to apply traffic calming is key to maximizing the impact of traffic calming investments made by the city. This guide is intended to educate users about specific traffic calming devices which have been proven to be effective on City streets. The purpose of this guide is to provide community members and leaders with a resource to understand what traffic calming tools are available, their benefits, and their limitations. This material is intended to be empowering. With an intentional deployment of traffic calming measures across the City of St. Louis, our streets can be safer for all by lessening or preventing speeding, crashes, and traffic deaths.

The Interstate 270 North corridor is a route of local, regional, and national significance carrying over 140,000 vehicles per day. The northern portion of the interstate from I-70 to Route H was built in the 1960s. It serves as a primary freight route for commercial vehicle traffic to bypass the city of St. Louis and is designated on both National Highway Freight and Strategic Highway Networks. During the I-270 North project, crews reconstructed or rehabilitated pavement and bridges; improved the roadway and interchanges to meet modern highway and safety standards; improved accessibility along and across the corridor for transit users, cyclists, and pedestrians; and made improvements to the interchanges and outer roads of the I-270 North Corridor. Local and state officials cut the ribbon on the corridor in December 2023 when most of the new construction was complete. MoDOT Director Patrick McKenna. "The updates significantly improve the communities and reconnect people's lives along the highway with the addition of improving the highway and its interchanges and outer roads, creating 10 miles of multi-use path and other pedestrian facilities, and building the first dedicated bus lane connecting the North County Transit Center to the St. Louis Community College." The project been recognized with several awards, including ITE's 2024 Transportation Achievement Award for Traffic Engineering. Read more at: https://www.modot.org/projects/I-270North
East-West Gateway Council of Governments’ (EWG) transportation safety initiative focuses on providing a safer transportation system for all users. To make progress towards a downward trend in fatal and serious injury crashes, EWG in partnership with CBB Transportation Engineers + Planners and regional safety stakeholders, developed the Gateway to Safer Roadways: St. Louis Regional Safety Action Plan (Action Plan). The Action Plan is both a call to action and a blueprint for how the Region can significantly reduce the number of people killed and seriously injured on roadways. Roadway fatalities and serious injuries are a serious public health and safety problem in the United States. The fatalities and serious injuries that result from roadway crashes are preventable and thus unacceptable. The Action Plan provides a collaborative approach to improve roadway safety equitably for motorized and non-motorized users. EWG is committed to an eventual goal of zero fatalities and serious injuries resulting from crashes on the surface transportation system. As a first step towards this goal, the Action Plan sets a target to reduce the number of fatalities and serious injuries resulting from roadway crashes in the EWG Region by 50% by 2050. While ambitious, this target is achievable through a concentrated, coordinated, and sustained effort. Read more at: https://www.ewgateway.org/gtsr/
