A 59-year-old man was struck by a car while walking in the travel portion of westbound Route 58 just east of Harrison Avenue Friday evening.
Patrick Padden, who police said has no known address, was transported to Stony Brook hospital with serious injuries following the 8 p.m. crash. A Stony Brook spokesman said Mr. Padden is listed in critical condition as of 2 p.m.
The driver of the vehicle, Francis Zebrowski, 89, of Aquebogue, is not expected to face criminal charges in the incident. The 1997 Buick Lesabre was impounded, however, for a safety check.
The investigation is ongoing and anyone who may have witnessed the crash is asked to call Riverhead police at 631-727-4500.
