Castle Hills sits inside a busy pocket of North San Antonio traffic: Loop 410 access roads, commuter cut-throughs, shopping centers, schools, and constant turning movements along the area’s main corridors. When crashes happen here, they tend to cluster where high speeds, heavy volume, and complex intersections collide.
This post shows you how to identify the highest-risk intersections on (or near) your Castle Hills commute using public, data-driven tools built from TxDOT crash records—and what to do if a crash leaves you or a loved one injured.
The data-driven definition of “deadliest”
When transportation agencies evaluate “most dangerous” locations, they usually prioritize fatal and serious-injury crashes—not just fender-benders.
San Antonio’s High-Injury Network (HIN) work is based on TxDOT’s Crash Records Information System (CRIS)and focuses on where fatalities and severe injuries concentrate. In that analysis, a disproportionate share of fatal and serious-injury crashes occurs on a small share of streets, which is exactly why identifying hotspots matters for everyday commuters. (San Antonio)
Why Castle Hills commuters should use a “network” approach (not anecdotes)
A single intersection can feel dangerous because you’ve seen crashes there, but the safest way to plan your route is to look at patterns over multiple years—especially for severe outcomes.
San Antonio’s published HIN methodology explains it used five years of TxDOT CRIS crash data (2019–2023) and weighted fatal/severe-injury crashes heavily to pinpoint the corridors most associated with life-altering outcomes. (San Antonio)
Important nuance for Castle Hills: the City’s HIN analysis focuses on streets within the City of San Antonio and can exclude streets owned by other municipalities. Castle Hills is its own municipality, so some segments inside Castle Hills may not appear the same way they do in San Antonio-only tools. (San Antonio)
That’s why you should treat the results as a high-value starting point—especially for the major roads you use every day that connect directly into San Antonio’s network.
The fastest way to find “deadliest” intersections near you: San Antonio’s HIN Dashboard
In December 2025, the City of San Antonio Transportation Department launched a public High-Injury Network Dashboard designed to show residents where severe and fatal crashes concentrate and to “highlight intersections and corridors with the highest rates of severe crashes.” (San Antonio)
How to use it for Castle Hills in 3 minutes
- Open the City’s High-Injury Network Dashboard (the public tool announced by the City). (San Antonio)
- Zoom to Castle Hills / North San Antonio (Loop 410, NW Military Dr, West Ave, Blanco Rd area).
- Toggle filters by mode (people walking/biking/driving) and focus on severe/fatal outcomes rather than all crashes. (San Antonio)
- Click the corridors/intersections that sit on your commute and note:
- Whether the corridor is flagged as high-injury
- Whether the issue is primarily pedestrian, bicycle, or all-modes
- Whether the risk appears concentrated at a signalized intersection, a merge, or a turn lane cluster
Castle Hills “check-first” intersections (high-volume, high-complexity)
Even before you open any dashboard, most Castle Hills commuters can identify the places where traffic complexity spikes. These are the first intersections and nodes you should type/zoom to in the HIN tool because they combine heavy volume, lane changes, turning conflicts, and frequent stops:
- NW Military Dr & West Ave (turning conflicts + lane changes)
- West Ave & Loop 410 access/frontage roads (merges, short decision windows)
- NW Military Dr & Loop 410 access/frontage roads (fast entries/exits + congestion)
- Blanco Rd & Loop 410 access/frontage roads (high-volume turning and weaving)
- West Ave & Wurzbach Pkwy (speed differentials + turning movement density)
- Blanco Rd & Wurzbach Pkwy (multi-lane crossings and turning traffic)
These are not presented as a “top 6 list” or a guaranteed ranking. They’re the most common Castle Hills-area “risk multipliers”—and the best places to start your route check using the TxDOT-based tools described above. (San Antonio)
Crash patterns that make intersections “deadly”
Across Texas, severe crashes at intersections frequently involve predictable mechanisms. When you’re assessing your route, watch for these patterns:
1) Left-turn failures (especially at multi-lane crossings)
A driver misjudges speed or gaps while turning left across oncoming traffic. These crashes can be catastrophic for occupants and especially dangerous for motorcyclists.
2) Rear-end crashes with severe outcomes
Not all rear-ends are minor. High speeds, distracted driving, or a stopped queue around a curve can turn a “routine” crash into a serious injury event.
3) Pedestrian crashes at crossings and driveways
The City’s safety messaging emphasizes intersections/crosswalks as key locations for severe pedestrian crashes—one reason the dashboard and awareness campaigns focus so heavily on crossings. (San Antonio)
4) Lane-change sideswipes that become loss-of-control collisions
Short merge areas near frontage roads or closely spaced driveways can cause sudden lane shifts—especially during congestion.
Practical safety steps for Castle Hills drivers (that actually match the risks)
- Approach signals like they could change: stale green lights near major corridors are where last-second decisions spike.
- Leave more space than you think you need in stop-and-go congestion near frontage roads.
- Scan for pedestrians at driveways (shopping centers are crash multipliers).
- Treat motorcycles as closer/faster than they look before turning left.
- Avoid “beat-the-merge” lane changes near Loop 410 access points—most sideswipes start as impatience.
If you’re hit at one of these intersections: what to do in the first hour
- Call 911 if anyone is hurt or traffic is blocked.
- Photograph everything (signals, lane markings, debris, skid marks, all vehicles, visible injuries).
- Get witness names/numbers—especially if a light phase or turn arrow is disputed.
- Request medical evaluation the same day if you have head/neck/back pain (some serious injuries don’t feel serious immediately).
- Preserve video (dash cam, nearby business cameras, home cameras). Many systems overwrite quickly.
When talking to a lawyer can help
Some intersection crashes become complicated fast—especially when the insurer argues:
- “You should have seen them,”
- “You entered late,”
- “You were speeding,” or
- “You weren’t injured that badly.”
A lawyer can help gather and preserve evidence (including video), evaluate fault theories, and document injuries in a way that matches how insurers actually analyze claims—particularly for car wrecks, motorcycle collisions, and pedestrian injuries.

Quick FAQ
How does the HIN Dashboard decide what’s high-injury?
It’s built to show where severe and fatal crashes concentrate, using TxDOT CRIS crash data and a methodology designed to prioritize serious outcomes. (San Antonio)
Will it show crashes inside Castle Hills city limits?
Sometimes. The underlying City analysis focuses on City of San Antonio streets and can exclude streets owned by other municipalities—so treat it as a strong starting point and focus on the major corridors that connect the area. (San Antonio)
What should I do if the intersection design feels unsafe even if I haven’t seen a crash there?
Use the dashboard to check whether the corridor is flagged; then consider reporting near-misses or signal visibility issues to the appropriate road authority. The goal is to align your concern with data and documented risk. (San Antonio)
