State Route 309 is a primary state highway in Northern Virginia, United States. It runs along Old Dominion Drive, the former Washington and Old Dominion Railroad right-of-way, from State Route 123 (Dolley Madison Boulevard) at McLean to U.S. Route 29 (Lee Highway) in Arlington. After a very short overlap with US 29, SR 309 splits onto Lee Highway, while US 29 uses Old Dominion Drive, to their junction at the end of SR 309.
