A 53-year-old man crashed his motorcycle Saturday night in Charlotte County and has been listed as in critical condition. Austin Simmons was headed northbound on Interstate 75 around 7:30pm when he tried to change lanes. Something caused Simmons to hit a concrete wall and then flip. He was taken to Lee Memorial Hospital after the Florida Highway Patrol got word of the accident. No other vehicles were reported to be involved and authorities do not believe alcohol was a factor.
