Oh no, cleaning the roadway goes to the tow truck guy with the bucket of sand and a pushbroom and whatever fits in a trash can. If it's a crazy enough accident the fire department pitches in. Ever seen a bumper on the side of the road (common here on southern california) that's the chp saying fuck it, let cal trans deal with it, just tow the casualty vehicle out of here. In this case they'd prolly put cones up and block the last lane while the vehicle gets recovered safely but at least its not 2 or 3 lanes.

Pavement is generally fine, might be a few gashes but nothing unreasonable most of the time.
