ROCHESTER - A Rochester teenager sustained life-threatening injuries on Thursday afternoon when his bicycle was struck by a car on the Route 16 onramp in the area of the Milton Road Dunkin' Donuts.

Police say William Stewart, 18, of 6 Jackson St., was riding his mountain bike south on Milton Road and was crossing the westbound onramp around 4:30 p.m. when he was struck by a 2012 Volkswagen Golf driven by Brandon Roy, 22, of New Durham, N.H. Roy had been traveling northbound on Milton Road prior to the crash.

When first responders arrived Stewart was unconscious lying on the onramp a few feet away from the Volkwagen. Police say the car sustained front end damage.

Stewart was flown by DHART helicopter to Maine Medical Center with serious, possibly life threatening, injuries. Roy was unharmed.

The Strafford County Regional Accident Reconstruction Team was called out to investigate the accident. The westbound on ramp to 202/11 from Milton Road was closed for a period of time.

Neither speed nor alcohol appear to be factors at this time, police say.
