for some reason, Vienna has decided to have roads that change their names as you travel along them.
For example, Chain Bridge Road becomes Maple Avenue and then Chain Bridge Road again.
Drive south on Lawyers Road and it switches to Courthouse Road at the Maple Ave. light.
Drive north on Old Courthouse Road and as you pass Trap Road it changes to Beulah Road.
Five Oaks Road crosses Courthouse Road and becomes Sutton Road.
