The Thanksgiving traffic cameras worth opening, Grapevine to the Cross Bronx
At dusk this evening the Caltrans camera on southbound I-5 at Grapevine Road had an unbroken string of lights strung along the grade, pale against brown hills, with the orchard rows coming right up to the fence on the right. That is an ordinary Friday. On the Wednesday before Thanksgiving the same frame is the one the helicopters go up for, and you can have it on a laptop for nothing.
Thanksgiving this year is Thursday 26 November, per the federal holiday schedule. What follows is the cameras I would actually open on the corridors that carry it, what each one points at, and the hour it is worth having up. The traffic hub counted 46,008 live traffic cameras in the United States when I checked it today, which is the problem rather than the answer: nobody needs 46,008 of anything. They need six.
Why the search results are no use
On 2026-10-31 I ran the search a person would run before a holiday drive and read the first page of it. Top result, a Fort Myers television piece about highway cameras in southwest Florida, now answers 404. A Central Virginia station published a live-conditions page on 2024-11-27 that points at Virginia 511 and Google Maps. A Miami story from 2013-11-26 says the state will monitor hundreds of cameras and links to fl511.com. Every one of them hands you a state 511 landing page and leaves you to find the camera yourself, which on the Wednesday afternoon is forty minutes you do not have.
So: named cameras, with the view, the cadence and the hour.
The two mountain cameras that pay off on the Sunday
Eastbound I-70 back into Denver on the Sunday after Thanksgiving is the jam that locals plan their whole weekend around. Two cameras carry it.
The I-70 camera 0.3 miles east of the Eisenhower Tunnel watches the eastbound lanes coming out of the bore and dropping away towards Bakerville. Tonight it was dark, wet tarmac under the portal floodlights, snow banked along the verge and one set of tail lights pulling east. In daylight on a holiday Sunday it shows you whether the queue has backed up into the tunnel, which is the only question worth asking about that road.
Twenty-five mileposts west, the Vail Pass summit camera sits at the top of the climb. Its overlay reads 0.7 miles east of the summit, eastbound, and at night it gives you very little: a black frame, a lit box on the central reserve, the odd vehicle. Open it between about 10:00 and 15:00 Mountain time, when the light is on the snow and you can see whether the plough has been through. Colorado's hub page lists 1,785 active cameras in the state, most of them CDOT, and these two are the ones I keep bookmarked.
Our record has both on a 30-second video cycle, checked again today. That is the slowest cadence on this list and still fast enough: a traffic jam does not change much in half a minute.
New York, where the frames carry the clock
Everyone leaving New York has an opinion about the Cross Bronx. Its camera at Arthur Avenue is a NYC DOT image feed, and the most honest one on this list, because the department burns the time into the top of the frame. A copy pulled at 01:19:59 UTC came back stamped 2026-10-30 21:19:58 local, one second before I asked for it. I fetched it five times at seventeen-second intervals and got five different frames. There is no cycle to wait for; you get the road as it is now.
What it shows at night is a deep cutting with the westbound carriageway coming at you in white and the eastbound going away in red, the service road above and the Bronx on the skyline. Crotona Parkway, half a mile east by the coordinates on the two pages, does the same job one junction along. The Bronx hub has 274 live cameras on it today, and these frames come straight from NYC DOT to your browser rather than through us, so what you see is what the city is publishing this second.
For the eastbound exodus onto Long Island, the Long Island Expressway at 99th Street looks down on the main lanes and both service roads at once, and tonight it was solid white one way and solid red the other with the Queens towers lit behind. Further out, I-495 at 220th Street catches you before the Nassau line. Queens has 445 live cameras. One honest gap: we hold nothing on the George Washington Bridge itself, so for the Hudson crossing the Cross Bronx cameras east of it are the closest you get.
Three more worth having open
The Downtown Connector in Atlanta is where I-75 and I-85 run as one road through the middle of the city, northbound at mile 246. The GDOT frame carries its own label and milepost, and tonight showed eight lanes of light traffic under the bridge deck at the I-20 split. On the Wednesday this is the first thing to go. Atlanta has 336 active cameras.
The Delaware Memorial Bridge camera at Interchange 1 is a New Jersey Turnpike camera on the approach, and at night it is pure infrared: a diagonal line of headlights cutting through black woodland, the green Welcome to New Jersey sign lit at the bottom of the frame. Worth it for the I-95 corridor between Washington and Philadelphia, where the bridge is the pinch point.
The Bay Bridge SAS tower camera looks west along both decks of I-80 with the tower cables in the frame and the azimuth and elevation printed in the corner. This evening the westbound side was packed solid and the carriageway beside it was moving. It is the best single frame of the Bay Area's Wednesday.
Back at the Grapevine, AlertCalifornia's wide camera on the same hillside is the one to open if the forecast turns, because fog and snow on the pass close I-5 more reliably than volume does. Kern county has 95 live cameras.
What we will be doing with them
Every camera on the site gets re-fetched and re-checked once a day, and these eleven go through that like the rest. Through the holiday week I will be watching the Grapevine and the Eisenhower portal myself, because those are the two where the picture tells you something the travel-time estimate does not: whether the queue is moving at all.
The thing I have not solved is the hour. A camera tells you the road is full; it does not tell you when it emptied last year. We hold the frames and we hold the timestamps, so the next useful thing to build is a view of the same camera at the same hour across several Thanksgivings. If you have seen anyone do that well with public camera archives, I would like the link.
