Charles Johnson has a pair of rather frightening screen captures from Fox News, and details from the Star-Tribune. Matt Drudge is currently linking to further details.

Update: Here's a live video feed from Minneapolis's WCCO.

Update: Via Hot Air, Dan Riehl notes that the bridge "Was Scene Of Ongoing Work".

WCCO reports:

A four-lane interstate bridge spanning the Mississippi River collapsed during evening rush hour Wednesday, sending vehicles and tons of concrete crashing into the water.

The entire span of the Interstate 35W bridge collapsed about 6:05 p.m. A tractor-trailer caught fire, and flame and black smoke billowed into the sky.

Local television stations captured video of injured people being carried up the riverbank. There was no official word on injuries, but dozens of rescue vehicles were there. Divers were also in the water.

Some people were stranded on parts of the bridge that aren't completely in the water.

"My truck got completely torn in half," said a witness who was on the bridge when it collapsed. "The bridge started shaking and it went down fast."

The Interstate 35W Mississippi River bridge near University Avenue has collapsed into the river.

Both the northbound and southbound lanes of 35W are lying in the Mississippi River.

There are multiple cars in the river and a couple cars on fire. According to one witness, there was a school bus full of children on the bridge.

Cars are still on the bridge.

Tons of concrete have collapsed and people are injured. Survivors are being carried up the riverbank.

Some people are stranded on parts of the bridge that aren't completely in the water.

A tractor-trailer is on fire at the collapse scene.

Some cars are still precariously perched on the bridge. Sections of the bridge are mangled, some are pointing up in the air and some are in the river.

"It is just horrific," said witness Marilyn Franzen, who saw the bridge collapse. Franzen said she saw a school bus that managed to stop before the going over the edge of the bridge that she said was carrying 20-30 children.

According to witnesses, cars are crushed and mangled under the bridge where it collapsed onto the shore of the river. Street signs also crushed cars.

Update: "Sixty children on the bus. Sixty children alive. There’s chance, and there’s miracles. Take your choice."--James Lileks is liveblogging the aftermath. Additionally, Breitbart.TV currently has numerous video clips from local TV stations of the collapse's aftermath.

Pajamas has a round-up with additional links, including Minneapolis-based bloggers such as Ed Morrissey and Power Line, along with an eye-witness description of the collapse from another local blogger, Blanked Out:

Surprisingly quiet, but my entire warehouse apt shook quite a bit. Bridge fell so very slowly - poof. Yelled and yelled but no one answered. Only a handful of ppl in water, all got out ok and then began to help as well. Ran into woman who thought school bus was trapped on east side in fold of highway. Couldn’t confirm it or get to the other bank to help.

more later…hope everyone is safe…

I live the closest to the 35W Bridge than anyone in Minneapolis and I watched it come down from my roof.

He adds, "PS This was not a bomb". To the best of my knowledge, no one at all is reporting that this is terrorist related; aging--and as we noted just last night, sometimes not so aging--infrastructure is quite capable of malfunctioning on its own.

Update: Seven currently reported dead, according to the latest Hot Air update, which includes to a massive ongoing update by WCCO.
