Houston TranStar Cameras — Live Road Cameras & Map
All Houston TranStar cameras — interactive statewide map
About this map
Houston TranStar is the joint traffic and emergency-management center that watches over the Houston region's freeways, and it is one of the most ambitious partnerships of its kind in the country. Four agencies share the same building near Memorial Park and the same camera network: the Texas Department of Transportation (TxDOT), Harris County, the City of Houston and METRO, the regional transit authority. Together they operate a vast field of traffic cameras across the metro area, and the live still images are what we pull onto this page so you can see the road before you commit to it. This page covers the Houston freeway system specifically, not the whole state of Texas.
The Houston network is organized around a simple geography: radial freeways that fan out from downtown, and ring roads that wrap the metro at increasing distances. The radials are Interstate 10 (the Katy Freeway heading west and the East Freeway heading east), Interstate 45 (the North Freeway toward Dallas and the Gulf Freeway down to Galveston), US-59/I-69 (the Southwest Freeway toward Sugar Land and the Eastex Freeway toward Humble and Kingwood), US-290 (the Northwest Freeway toward Cypress and Tomball) and SH-288 (the South Freeway). The rings are Loop 610 (the Inner Loop tight around the urban core), Beltway 8 (the Sam Houston Tollway) and SH-99 (the Grand Parkway, the outermost loop), with the Hardy and Westpark tollways adding extra spokes.
One important note about how this page reads the weather. These Houston cameras are traffic cameras, not road-weather stations, so they carry no pavement or air sensors of their own. Instead, we show the nearest airport's conditions alongside each camera, drawn from National Weather Service observations at fields like George Bush Intercontinental (IAH) on the north side and William P. Hobby (HOU) on the south side. That gives you a reliable read on temperature, wind, rain and Gulf fog near the camera, but it is a regional reading rather than a measurement of the specific stretch of pavement. When Houston floods or fogs in, trust the live picture over the number. These are refreshing still images, so reload to see the latest frame.

Houston Metro
The full regional view: every radial freeway and every ring road that Houston TranStar watches, from the Inner Loop out to the Grand Parkway. Start here for a wide read on the whole metro, then zoom into a district preset to focus on the corridor that matters for your drive. This is the preset to open when you want to compare conditions across town before deciding whether to take a freeway, a ring road or a tollway.
Downtown & Inner Loop
The dense core where the radial freeways collide with Loop 610. This is the busiest, most camera-rich part of the network, covering the downtown interchanges where I-10, I-45 and US-59/I-69 weave together, the Spaghetti-Bowl-style stacks, and the tight wrap of the Inner Loop. Buffalo Bayou runs through here, so watch these cameras closely during heavy rain when downtown underpasses and ramps are the first to take on high water.
West & Katy
I-10 West, the Katy Freeway, running out past the Energy Corridor toward Katy and the Grand Parkway. The Katy Freeway is one of the widest freeways in the world here, and even with all those lanes it backs up hard at rush hour. This district also caught some of the worst flooding during Hurricane Harvey when the Addicks and Barker reservoirs were released into Buffalo Bayou, so the West and Katy cameras are worth a look any time a major rain event is forecast.
North & The Woodlands
I-45 North (the North Freeway) and the Hardy Toll Road climbing toward Spring and The Woodlands, plus US-290 (the Northwest Freeway) toward Cypress and Tomball. These corridors carry heavy suburban commuter volume into the core every morning and back out every evening. The nearest airport conditions here usually come from George Bush Intercontinental (IAH), which sits in this northern wedge of the metro.
Southwest & Sugar Land
US-59/I-69, the Southwest Freeway, heading out through the Galleria area toward Sugar Land, Missouri City and Richmond in Fort Bend County, with the Westpark Tollway running parallel as the faster toll alternative. The Southwest Freeway just outside Loop 610 was once among the busiest stretches of highway in North America, and it still ranks among Houston's most reliably congested corridors at peak times.
Southeast, Clear Lake & Galveston
I-45 South, the Gulf Freeway, running down through Pasadena and Clear Lake toward the coast and Galveston, with SH-288 (the South Freeway) on the western side of this wedge. This is the hurricane-evacuation and Gulf-fog district: I-45 is a primary contraflow evacuation route off the coast, and low-lying coastal fog and storm surge make these the cameras to check before any drive toward Galveston Island.
Tips for using Texas road cameras
- Compare before you commit. Houston gives you parallel options almost everywhere, so glance at the freeway and at the nearby tollway or ring road before you leave. If the Katy Freeway is red, the Westpark Tollway or Beltway 8 may save you; if I-45 is jammed, the Hardy Toll Road is the relief valve.
- Watch for high water first. Houston floods notoriously, and underpasses, ramps and bayou crossings take on water fast during heavy rain. During a flash-flood warning, use the cameras to confirm a route is actually passable, and never drive into water you cannot see the bottom of.
- Treat the weather reading as the nearest airport, not the road. The conditions beside each camera come from the closest NWS airport station, like IAH on the north side or Hobby on the south side. It is a good regional gauge of rain, wind and fog, but it does not measure the pavement in the frame.
- Reload for a fresh frame. These are refreshing still images rather than live video, so if a picture looks stale, refresh the page to pull the latest capture before you rely on it.
- Plan around Gulf fog on the southeast side. Dense morning fog off Galveston Bay can settle over I-45 South and the Clear Lake corridor with little warning. The live picture tells you far more about visibility than the temperature number does.
- Know your evacuation arteries. During a hurricane threat, I-45, I-10 and US-59 are the main routes inland, and lanes can be switched to contraflow heading away from the coast. Check the cameras along your planned route early, before traffic and weather both build.
