Metro Transit officials say a support vehicle and not a Metro Mobility bus rolled over earlier this morning on the ramp from northbound Hwy. 252 to Hwy. 610.  Initial reports indicated it was a Metro Mobility bus.

Spokesman John Siqveland said the vehicle's lone occupant was taken to Mercy Hospital with unknown injuries. The driver will tested for drugs and alcohol per standard procedure.

Metro Transit Police and other law enforcement are investigating.  The ramp at this time is blocked but open to traffic.  Eastbound and westbound traffic slows in the immediate area.
