text:  Washington County Fire and Rescue says units responded just after 3.30 and found a large fire on the bridge which was spreading rapidly. Due to the high temperatures and extensive fire damage, additional units from Washington County as well as Jefferson and Frederick Counties were called to the scene, along with water tankers from all three jurisdictions because of the limited water supply access in the area. Two boats were brought in as a precaution due to firefighters working on an elevated structure over the Potomac River.
