Houston intersections with the most serious crashes (2021–2023)
A count of crashes that killed or seriously injured someone at Houston intersections from 2021 to 2023, from City of Houston Vision Zero data, with the method, the limits and a downloadable CSV.
The short answer
From 2021 to 2023, the Houston location with the most crashes that killed or seriously injured someone was Beltway 8 at Bissonnet Street, with 9 such crashes, followed by I-45 at West Greens Road and Beltway 8 at West Bellfort with 8 each, according to City of Houston Vision Zero data. Nine of the 17 locations listed below are on Beltway 8 or the Southwest Freeway (US-59/I-69) in southwest Houston.
These are counts from official data, not a measure of how risky an intersection is to drive through. The study is general information about public data, not legal advice, and it says nothing about any particular crash.

- Source. The City of Houston's Vision Zero layer of traffic deaths and serious injuries (January 2018 to May 2024, built from TxDOT's crash records system, CRIS; layer last updated 2024-08-21). See Vision Zero Houston.
- Years. 2021, 2022 and 2023, the three most recent full years in the City data.
- What is counted. Crashes in which at least one person was killed or suspected seriously injured ("KSI crashes") that the reporting officer marked as at or related to an intersection: 1,844 crashes with a mapped location.
- What is listed. The 17 locations with 5 or more KSI crashes whose street names we confirmed on a map. Together they account for 100 of the 1,844 crashes (about 5%); most serious intersection crashes happened at locations with only one or two.

Which Houston intersections had the most serious crashes?
Locations with the same number of KSI crashes share a rank. Within a tie, rows are ordered by fatal crashes, then by people hurt.
| Rank | Intersection | KSI crashes, 2021–2023 | Fatal crashes | People killed | People seriously injured |
|---|---|---|---|---|---|
| 1 | Beltway 8 at Bissonnet St | 9 | 1 | 1 | 9 |
| 2 | I-45 at W Greens Rd | 8 | 3 | 3 | 5 |
| 2 | Beltway 8 at W Bellfort | 8 | 1 | 1 | 9 |
| 4 | US-59/I-69 at Beltway 8 | 7 | 1 | 1 | 7 |
| 5 | US-59/I-69 at W Bellfort | 6 | 1 | 1 | 6 |
| 5 | Beltway 8 at Westpark Dr | 6 | 0 | 0 | 8 |
| 5 | US-59/I-69 at Westpark Tollway | 6 | 0 | 0 | 6 |
| 8 | US-59/I-69 at Bissonnet St | 5 | 1 | 1 | 7 |
| 8 | Beltway 8 at Harwin Dr | 5 | 1 | 1 | 4 |
| 8 | US-59/I-69 at Orlando St | 5 | 1 | 1 | 4 |
| 8 | Bellfort at Stassen St | 5 | 0 | 0 | 8 |
| 8 | Homestead Rd at Hartwick Rd | 5 | 0 | 0 | 8 |
| 8 | Little York Rd at Aldine Westfield Rd | 5 | 0 | 0 | 7 |
| 8 | I-610 at Martin Luther King Blvd | 5 | 0 | 0 | 6 |
| 8 | Beltway 8 at Pearland Pkwy | 5 | 0 | 0 | 5 |
| 8 | I-10 at Federal Rd | 5 | 0 | 0 | 5 |
| 8 | US-59/I-69 at Hillcroft Ave | 5 | 0 | 0 | 5 |
"US-59/I-69" is the Southwest Freeway at every location in the table except Orlando St, where it is the Eastex Freeway. "I-610" at Martin Luther King Blvd is the South Loop. At freeway locations, the count includes crashes on the frontage roads where they cross the street, which the crash records file under the freeway's name.
What stands out in the data?
- Southwest Houston. Seven of the listed locations lie within about five miles of each other along Beltway 8 and the Southwest Freeway, between Westpark Dr and W Bellfort, and two more are on the Southwest Freeway near Hillcroft Ave and the Westpark Tollway.
- Mostly serious injuries, few deaths. Of the 100 crashes at these 17 locations, 10 were fatal. They killed 10 people and seriously injured 109.
- Small numbers. Five crashes in three years is a small count. One crash more or less moves a location several places, so treat the order as approximate.
How was this study done?
- Data. We downloaded the City of Houston's public traffic deaths and serious injuries layer on 2026-10-22. It has one row per person killed or seriously injured; we collapsed it to one row per crash.
- Filter. We kept crashes from 2021 to 2023 that the officer marked "intersection" or "intersection related" and that have a map location (1,844 crashes; 6 had no location).
- Grouping. We grouped crashes within about 250 feet (76 meters) of each other: repeatedly taking the point with the most crashes around it, counting that group as one location, and repeating with the crashes left.
- Naming. Each location was named from the street names in its own crash records and the City's street map, then checked against OpenStreetMap street data within about 260 feet (80 meters) of the location's center. A location is listed only if both street names were found there. Every location with 5 or more crashes passed this check.
- Cut-off. We list every confirmed location with 5 or more KSI crashes. The cut-off does not split a tie: the next locations have 4 crashes each, and several share that count.
The scripts, the full method and the name-check results are published with the data. The data and this page contain counts only; nothing identifies any person.
What are the limits of this study?
- Counts, not rates. The data does not include traffic volumes, so a busy intersection can have more crashes without being riskier for any one trip.
- Serious crashes only. The public City layer has only crashes with a death or suspected serious injury. Minor-injury and property-damage crashes are not counted.
- Officer judgment. Whether an injury was "serious" and whether a crash was "intersection related" are recorded by the reporting officer.
- Grouping can merge or split. At large freeway interchanges, crashes on both frontage roads can fall into one group; at very large intersections, crashes can split into two.
- City data only. The layer covers crashes in and near the City of Houston, from January 2018 to May 2024. Newer City crash points were not publicly available when we checked.
- No causes. The counts do not say why any crash happened or who was responsible.

Frequently asked questions
- Which Houston intersection had the most serious crashes from 2021 to 2023?
- In City of Houston Vision Zero data, the location with the most crashes that killed or seriously injured someone from 2021 to 2023 was Beltway 8 at Bissonnet Street in southwest Houston, with 9 such crashes. I-45 at West Greens Road and Beltway 8 at West Bellfort followed with 8 each.
- Are these the most dangerous intersections in Houston?
- The data does not show that. It counts crashes in which someone was killed or seriously injured; it does not account for how many vehicles or people pass through each intersection, so a busy intersection can have more crashes without being riskier for any one trip. The counts are also small, and one or two crashes can change the order.
- Where does this data come from?
- From the City of Houston's public Vision Zero layer of traffic deaths and serious injuries, which the City built from TxDOT's Crash Records Information System. It covers January 2018 to May 2024; this study uses the three most recent full years, 2021 to 2023.
- Can I use this study to look up a specific crash?
- No. The study publishes counts by location only, with no crash-level records. The official record of a crash is the Texas crash report (form CR-3), which can be purchased through TxDOT's Crash Records Information System.
