Route description

Route 173 begins at an intersection with US 5 and Route 15 in Newington and briefly heads west on Richard Street before turning north onto Willard Avenue. It briefly overlaps with Route 174 and meets Route 175 before continuing into West Hartford, where it becomes Newington Road. In Elmwood Center, it turns west onto New Britain Avenue, and turns north again onto South Main Street as it meets the northern end of Route 71, onto which New Britain Avenue continues. It intersects I-84 shortly before ending at an intersection with Hooker Drive.^[1]

History

Route 173 was commissioned in 1932.^[2] It originally went using South Quaker Lane to Farmington Avenue (then Route 4) in West Hartford. In 1962, Route 173 was truncated to end at Route 71. However, in 1969, it was re-extended slightly to I-84 along South Main Street (former SR 569) via a short overlap with Route 71.^[4]
