One person was killed Monday in a collision on a Highway 401 off-ramp in Milton.

The collision occurred over the noon hour, on the ramp from the highway’s eastbound lanes to Highway 25.

OPP say they were pursuing the vehicle as it left the highway through the median.

“It actually launched over the southbound-to-eastbound ramp and came to a rest beyond the ramp,” Sgt. Kerry Schmidt said in a Periscope video.

A vehicle fire was also said to be involved in the incident.

Information on the victim’s identity had not been made public as of mid-afternoon.

The ramp remained closed until about 3:45 p.m., with online traffic maps showed eastbound traffic slowdowns extending nearly to Highway 6 South.
