Route description
Route 73 begins at an intersection with Route 63 in the town center of Watertown. It begins as Main Street, splitting off to the east from Route 63. It travels east southeast, crossing over Steele Brook, into the Oakville section of town. In Oakville, it has a junction with Buckingham Street, an unsigned state road linking Route 73 to Route 262. Route 73 soon enters the city limits of Waterbury as Watertown Avenue, crossing over Steele Brook again. East of the intersection with Irvington Avenue, Route 73 widens to four lanes. After about 0.2 miles (0.32 km), Route 73 leaves Watertown Avenue and becomes an expressway for its final 0.6-mile (0.97 km) length. Route 73 ends as it merges with southbound Route 8 (at Exit 31).
