Eastbound traffic on the Richmond-San Rafael Bridge came to a complete halt this morning following a tractor-trailer fire that broke out mid-span on the 5.5-mile bridge. ABC 7 reports that according to CHP officials on the scene, the fire was sparked by a collision between the big rig and another vehicle.

While at present there are no reported injuries and the fire has been extinguished, the road remains closed as officials work to clear the rubble.

Smoke, meanwhile, can be seen from some distance.

The Chronicle reports that this all went down around 8:00 a.m., and while the fire is out, The San Raphael Fire Department informs us that there is at present no estimated time for when the eastbound lanes will reopen.

In other words, it's probably best to avoid the entire area if possible.
