The Iowa State Patrol says the driver of a motorcycle was injured this (Friday) afternoon, when he struck a chunk of asphalt that had broken off the side of the road. The asphalt piece at some point came to rest near the center of the I-80 eastbound off-ramp at the Minden exit. The motorcycle, a 2004 Harley Davidson, struck the debris at around 12:48-p.m. and went out of control, causing the driver, 57-year old Christopher Mathison, of Council Bluffs, to be ejected from the machine. Mathison was transported by Minden Rescue to Mercy Hospital in Council Bluffs.
