Valhalla and Elmsford Fire Departments were dispatched to the Sprain Brook Parkway at Grasslands Road for a motor vehicle accident with injuries and a rollover. While en-route, units were given an updated location farther North near the Bradhurst Avenue Overpass putting it in the Hawthorne Fire District. Crews stabilized the vehicle and mitigated fluids on the roadway while EMS tended to the patient. Valhalla units were released by Hawthorne command soon after.
