Its western terminus is on U.S. Route 27 at State Route 732 in Oxford, where State Route 73 and U.S. Route 27 run concurrent for less that 1 mile. State Route 73’s eastern terminus is in Portsmouth at U.S. Route 23; this is also the southern terminus of State Route 104, and the two state routes run concurrent for over 6 miles from this point north.
