Lawmakers have introduced a bill to rename a bridge in honor of a fallen southwest Virginia state trooper. Virginia SB 1789 was introduced yesterday. If passed, it would designate the bridge on Interstate 81 over Whitetop Road as Trooper Lucas B. Dowell Bridge. That is the bridge at exit 35 in Chilhowie. Trooper Dowell was a Chilhowie native who was killed while helping serve a search warrant in Farmville, Virginia on February 4th.
