Emergency crews are responding to a single-vehicle rollover Thursday afternoon on Interstate 35W and Ramsey County Road 10, where at least one person was ejected from the vehicle.

The accident, which occurred about 3 p.m., backed up traffic for at least five miles because two of the three northbound lanes on I-35W and the ramp from County Road 10 had to be closed.

The traffic clog began loosening at 4 p.m. with two of the three lanes on northbound I-35 open.

No other details about the crash are available.
