    The Most Dangerous Intersections in St. Louis, Missouri

    October 3, 2025 | Car Accidents, Missouri Personal Injury

    St. Louis faces a growing crisis on its streets. With 126 people injured and one person killed at just one intersection alone, and 173 people killed with nearly 15,000 injured in car crashes across the city and county in 2022, understanding where accidents occur most frequently has never been more critical[source][Crash Data Portal]. This comprehensive analysis examines the most dangerous intersections in St. Louis based on recent crash data and traffic safety reports.

    Washington & Broadway: The Deadliest Intersection

    Leading the list of St. Louis’s most hazardous intersections is Washington & Broadway, where statistics show that 126 people were injured and one person died in recent years[regional safety report]. This busy downtown intersection poses particular risks due to its proximity to convention traffic and high pedestrian volume, as well as its close access to major highways[traffic safety facts].

    Top 10 Most Dangerous Intersections in St. Louis

    Based on comprehensive crash data analysis, these intersections consistently rank as the most hazardous in St. Louis:

    1. Washington & Broadway

    • 126 injuries, 1 fatality recorded
    • High pedestrian and vehicle volume
    • Proximity to major highways amplifies collision risk

    2. Kingshighway Boulevard & Lindell Boulevard

    This intersection serves as a gateway to Forest Park and experiences major congestion from commuters, cyclists, and pedestrians. For defensive driving tips, see the NHTSA’s safe driving guides.

    3. South Kingshighway & Interstate 64 (Highway 40)

    A key intersection connecting downtown to central neighborhoods and notorious for frequent, often severe, collisions due to poor visibility and high speed differences.

    4. Grand Boulevard & Forest Park Avenue

    Near St. Louis University, this intersection had 80 reported accidents in 2024, including 19 injuries. For more information on urban road design, check the Federal Highway Administration’s Proven Safety Countermeasures.

    5. South Jefferson Avenue, Sidney Street & Gravois Avenue

    A complicated multi-road crossing that creates confusion and frequent fender benders.

    6. Grand Boulevard & Interstate 64

    Risky due to merging traffic from the interstate and heavy arterial flow.

    7. Gravois & Lindbergh Boulevard

    Widely recognized as exceptionally hazardous due to fast traffic and complex merges. For Missouri Department of Transportation safety programs, visit MoDOT’s official site.

    8. North Grand Boulevard & Montgomery Street

    Identified as the “most dangerous” by national media analyses due to high speeds and lack of traffic control[].

    9. I-70 & Goodfellow Boulevard

    Part of a trend of dangerous interstate intersections=.

    10. Natural Bridge & Kingshighway

    Another intersection along the problematic Kingshighway corridor.

    Why Are These Intersections So Dangerous?

    • High-speed arterial roads with inadequate pedestrian protections.

    Traffic Volume and Behaviors

    • Peak-hour congestion, distracted driving, speeding
    • High-risk merging and insufficient signage

    Socioeconomic Disparities

    Disproportionately high crash rates afflict neighborhoods with less infrastructure investment. For more on addressing such disparities, read the Smart Growth America Dangerous by Design report.

    City and State Safety Initiatives

    St. Louis has allocated $46 million in ARPA funds to implement traffic calming and road safety projects at the most dangerous intersections, led by the Principal Arterial Traffic Safety program.

    Missouri’s Department of Transportation and St. Louis County have partnered for an additional $4 million safety initiative across 33 critical locations. To learn more about traffic enforcement and safety programs, visit MoDOT’s Safety Page.

    My experience with Ortwerth Law was seamless. In my case, Craig had to take on a giant company, and handled everything professionally all the way to satisfactory closure. Craig was engaging, and faithful to keep me informed along the way. There is no one else I'd rather recommend.

    Having Craig work on my case from beginning to end was the best decision I'd ever made! My case went on for 3 1/2 years and during that time i never had to worry about "bothering him or his staff with questions, or their patience in explaining what was going on or what I needed to do. They kept me and everyone involved informed and things went along smoothly! I hope to never have a case like this again, but if I do, there is absolutely NO doubt in my mind as to where I'd go and who I'd have to handle my case!! I highly recommend anyone to at least sit down for a consult. YOU WILL NOT BE DISAPPOINTED!! Great Job Craig (& Marcie!!)

    I grew up playing sports with Craig since grade school. Dedication, determination, and commitment lead to his success as an athlete and now leads him to be successful in law. When I was in a accident several years ago I called to ask for his help. He took care of all the legal tasks while I concentrated on physical therapy. I have recommended several of my friends and family to Craig and he has given them the same commitment and assistance. I endorse Craig and his firm for anyone needing legal service.

    I’m so grateful that Craig Ortwerth and his office took on my car accident case. Craig was so easy to work with and he quickly replied back to any questions or concerns I had and explained every step to me. I felt such relief knowing I was in good hands and I didn’t have to worry about dealing with the insurance company so I could focus on healing from my accident.

    Brian is an outstanding attorney! I had a pretty complicated divorce and it was not an easy time for me. Brian was thoughtful and empathetic to my situation. He wasn’t some cold attorney sitting across from me nodding his head. He was very responsive to any and all concerns I had, and never made me feel like a bother. He knows his profession and does it well. His prices are more than fair.

    As the Office Manager at Healthcare Complete, I would highly recommend the legal services from Brian McChesney and Craig Ortwerth. We have routinely referred our personal injury patients in need of legal advice/representation to their firm, and our patients have ALWAYS been well represented and satisfied. On a personal level, I have been represented by their firm for a personal injury case and have been equally satisfied. I have referred family and friends to the firm for similar situations. Our office, Doctor and Staff hold the firm in high regard. Thanks for all you've done for us through the years!

    This was the first time I have ever needed a lawyer. And Craig Ortwerth was refered by a friend he made this process easier than I could have ever imagined. All I had to do was sign a few papers and everything else he took care of. I'm so happy with the outcome and working with Craig was great.
