Top 5 Most Dangerous Intersections in St. Louis (and How to Avoid Them!)

Dangerous Intersections

Navigating St. Louis’ bustling streets can be a challenge, especially at intersections known for a higher risk of accidents. There are numerous true accounts of St. Louis car crashes that highlight the unexpected turns events can take. 

In this article, we’ll discuss the top 5 most dangerous intersections in St. Louis, along with tips on how to avoid becoming a part of the statistics.

Alarming Cases and Statistics

Statistics paint a grim picture, with over 35,000 reported crashes in St. Louis City and County in 2022 (according to the Missouri Department of Transportation). 

A motorcycle accident at the busy intersection of Utah Street and South Jefferson Avenue in St. Louis claimed the lives of two people. The crash left a witness, Amy Owens, shaken by the aftermath.

Although under investigation, bystander accounts suggest the motorcycle was speeding southbound on Jefferson before colliding with a car. The issue of speeding and red light violations on Jefferson Avenue is a growing concern for residents.

Another resident, who preferred to stay anonymous, expressed frustration with the frequent accidents and close calls. She called for the city to implement traffic calming measures like additional stop signs, speed signs, and traffic lights.

This is definitely a repeated safety issue raised about Jefferson Avenue. Last year, a series of accidents near the intersection with Russell Avenue prompted similar calls for action. The upcoming repaving project funded by American Rescue Plan money doesn’t currently include any safety improvements, according to city documents.

While some residents, like Owens, believe better driving habits are the key solution, the investigation into the accident and the ongoing issue of speeding on Jefferson Avenue highlight the need for a multi-pronged approach to improve safety on this dangerous roadway.

Remember, staying safe on the road is a shared responsibility, and you may face an accident even if you are a safe driver. If the unforeseen does happen anyway, your best bet is to get in touch with a St. Louis car accident lawyer.

Here’s our list of the top 5 most dangerous intersections in St. Louis:

1. Grand Boulevard & Interstate 64 Exit

This notorious intersection sees a high volume of traffic merging from I-64 onto Grand Boulevard, often leading to congestion and confusion.

If possible, consider using alternate routes to avoid this busy area during peak traffic times. If you must navigate this intersection, be extra cautious and allow ample following distance when approaching merging vehicles.

St. Louis’ I-64 corridor is reportedly getting a safety makeover. The Missouri Department of Transportation’s (MoDOT) Future64 project aims to improve a 3-mile stretch of the interstate, prioritizing safety and accessibility for everyone. Future64 will redesign confusing interchanges and address speeding issues to create a smoother flow for drivers, especially those unfamiliar with the area. 

Public input is crucial, and MoDOT is actively seeking feedback throughout the year. The project is currently in the planning phase, with a focus on minimizing environmental impact and weighing different improvement options. Future64 promises a safer and more user-friendly I-64 experience for all.

2. Natural Bridge Avenue & Kingshighway Boulevard

This busy intersection has a complex layout with multiple lanes and turning options, making it a breeding ground for accidents.

If possible, opt for a different route, especially if you’re unfamiliar with the layout. If you must use this intersection, pay close attention to lane markings and signage, and double-check blind spots before changing lanes.

3. Interstate 70 & Salisbury Street

In a recent tragedy here in February, a head-on crash between a Subaru and a Ford pickup claimed the life of the Subaru driver, who wasn’t from the area. The eastbound pickup truck left the road and hit the Subaru on the shoulder. The cause is under investigation, but the truck driver wasn’t seriously hurt.

High speeds on I-70 and a short merging lane from Salisbury Street create a dangerous situation for drivers entering the highway.

Ensure you have enough speed to merge safely with I-70 traffic. If unsure, consider using the on-ramp acceleration lane to gain speed before merging.

4. Washington Avenue & Broadway

This downtown intersection sees heavy traffic flow and a high number of pedestrians, creating a potential hazard for both drivers and walkers.

Be extra cautious when turning at this intersection, yielding to pedestrians and allowing ample stopping distance. If possible, plan your route to avoid this busy area during peak pedestrian times.

5. Kingshighway Boulevard & Lindell Boulevard

Located near St. Louis University, this intersection experiences a high volume of student traffic and pedestrians crossing between campus and nearby businesses.

If possible, utilize alternative routes to bypass this student-heavy area. If you must use this intersection, be mindful of pedestrians and allow ample time for them to cross safely.

St. Louis is revamping Kingshighway, a roughly 9-mile corridor known for its high accident rate. Traffic calming measures like curb extensions, medians, and improved crosswalks will be implemented. Funding comes from designated road improvement money. While residents welcome the changes, some believe more police enforcement and driver behavior modification are also necessary for lasting safety improvements.

TorHoerman Law shares tips to always prioritize defensive driving habits. Stay alert, maintain a safe following distance, and avoid distractions like phones while navigating any intersection, especially those on this list.

By being aware of these high-risk areas and practicing extra caution, you can significantly reduce your chances of being involved in an accident and navigate St. Louis’ roads with greater confidence.


1. Should I Contact a Lawyer After a Minor Car Accident?

Even for a fender bender, talking to a lawyer is a good idea.  Sometimes injuries aren’t obvious right away, and there might be more damage to your car than you first think.  A lawyer can explain your options, make sure you’re treated fairly by insurance companies, and fight for what you’re owed.

2. I’m a Cyclist, and These Busy Intersections Worry Me. Any Safety Tips for Me?

Cyclists can navigate busy intersections safely by prioritizing visibility with bright lights and reflective clothing. Staying alert, avoiding distractions, and anticipating car movements are crucial. Defensive riding, assuming drivers may not see you, and leaving ample space are essential for safety. Most importantly, invest in a helmet – your best defense in a crash.

3. As a Parent, How Do I Boost My Teens Driving Skills?

Take advantage of everyday errands, but don’t fall into a rut! Varying your driving routes exposes your teen to new situations and traffic patterns. Let your teen navigate – choose a destination and plan a different route together. Have them track your location – it keeps them focused and builds map skills. This practice, even on familiar errands, prevents “zoning out”.

While St. Louis addresses accident hotspots with the “Top 5 Most Dangerous Intersections” list and the Kingshighway revamp project, staying safe requires a multi-pronged approach. The future holds promise with MoDOT’s I-64 corridor improvement initiative prioritizing safety and accessibility for all. Remember, awareness, caution, and responsible behavior are key to navigating St. Louis streets confidently.
