Deer Park's crash record from TxDOT CRIS — where crashes cluster; the beyond-blame design analysis is the layer being built.
The SH-225 industrial corridor — the crash record
Killed and seriously injured on a state freeway threaded through town — read as design, not blame
Start here: on the SH-225 corridor, 81derived — TxDOT CRIS (K fatal + A serious injury) people were killed or seriously injured in five years. Over 2021-2025TxDOT CRIS, TxDOT’s Crash Records Information System (CRIS) recorded 4,069I-610 to SH-146 reported crashes on State Highway 225 in Harris County — 18TxDOT CRIS of them fatal, 63TxDOT CRIS with a suspected serious injury. Killed-or-seriously-injured is the number that matters, and it is the one this Studio leads with.
This is the whole SH-225 corridor — the La Porte Freeway from I-610 to SH-146 — not Deer Park’s alone. The corridor runs through Pasadena, Deer Park, La Porte, and unincorporated Harris County; Deer Park is one stretch of it. These are the corridor’s crashes, counted once. Because 2024 and 2025 are still provisional in CRIS, the Studio reads the five-year total, not a year-by-year trend.
Whose road this is. SH-225 is a TxDOT state highway — a controlled-access freeway the state designates, designs, and maintains (Minute Order 016701, 1939; TxDOT Houston District). Its lane widths, speeds, ramps, and frontage-road structure are the state’s decisions, not the City of Deer Park’s. Naming who owns the design is the first honest step in reading the record. (TxDOT highway designation file, SH0225; TxDOT Houston District)
Reading the record beyond blame. Strong Towns’ Crash Analysis Studio reads crashes as design outcomes, not only driver error — the same event a police report codes to a driver, the design lens asks what the road invited. On SH-225 the corridor’s own CRIS data is design-legible:
- 1,369derived — TxDOT CRIS (both-straight rear-end 915 + one-straight-one-st same-direction rear-end crashes and 933TxDOT CRIS same-direction sideswipes — the signature of high-speed, high-volume flow with merging conflicts.
- 614TxDOT CRIS single-vehicle-going-straight crashes — run-off-road and lane-departure events, where a vehicle leaves its lane and finds something to hit.
- The single largest contributing factor CRIS records is failed to control speed (885TxDOT CRIS crashes), with failed to drive in a single lane (259TxDOT CRIS) next.
Those last two are coded to drivers. Read through the beyond-blame lens they are also a description of the road: a mid-century freeway carrying heavy truck and hazmat traffic at freeway speed through an industrial-residential town produces speed-and-lane-departure crashes. The Studio states the pattern and attributes the frame to Strong Towns; it draws no verdict on any road or any body. (Manner of collision & contributing factors: TxDOT CRIS, SH-225 Harris County, 2021-2025. Framework: Strong Towns — beyond-blame, crashes-as-design.)
A second frame — inside Deer Park’s city limits. Separately from the corridor, CRIS records 5,065data as of 08/11/2026 reported crashes within the City of Deer Park’s own jurisdiction over 2015–2024, 44%data as of 08/11/2026 of them (2,211data as of 08/11/2026) intersection-related. That is a different filter — city jurisdiction, a different window — and it is not the corridor number above; the two are not added together.
The corridor and the plants. SH-225 is the highway that serves the Houston Ship Channel refineries and petrochemical plants — the same industrial corridor whose fiscal footprint the District tab records. The Studio states the corridor’s function and its crash record side by side; it does not claim industrial traffic causes the crashes. What the corridor carries and what the record shows are both facts; the reader draws the line.
Two records, one map. Every geolocated crash placed where it happened, colored by severity. The SH-225 industrial corridor runs the length of the freeway through Pasadena, Deer Park, and La Porte — the corridor’s crashes, whoever’s stretch they fall on. Ringed in cyan and clustered inside Deer Park are the city’s own city-street crashes: 1,730derived — TxDOT CRIS via civic.crashes view-layer (jurisdiction + road over 2021-2025TxDOT CRIS, 5derived — TxDOT CRIS via civic.crashes view-layer fatal, 30derived — TxDOT CRIS via civic.crashes view-layer killed or seriously injured. These are two different roads under two different owners — the state freeway and Deer Park’s own streets — drawn from one deduped record, told apart by geography and the ring.

How the two layers are built: one deduped crash table, split by attribute — the corridor is road‑class = state highway; the city-street layer is jurisdiction = Deer Park (by point-in-polygon against the county’s city limits) and not a state highway. Both are 2021-2025TxDOT CRIS. That window is a different frame from the 2015–2024 city figure above (5,065data as of 08/11/2026); the two are not added together. Imagery: USGS public-domain orthoimagery. (TxDOT CRIS + PostGIS point-in-polygon vs TIGER 2024 city limits; corridor County=Harris Highway=SH0225; city County=Harris City=Deer Park, 2021-2025)
The record shows the corridor’s crashes and the design patterns in them, cited to CRIS and read through a named framework — no verdict drawn for you. What a state does about a state road is a public decision; Think and Act Locally is where residents raise it.
