Route 145 is a circuitous south–north urban state highway in Massachusetts. It is entirely within Suffolk County and primarily serves the peninsular town of Winthrop from East Boston and Revere.

Although it is officially a south–north highway, Route 145 travels in each of the four main compass directions at some point along its route. Route 145 begins at the intersection of Neptune Road and Bennington Street in East Boston, just after the point where the Mass Pike/I-90 ends and merges with Route 1A. An access road from Route 1A junction travels a short distance on Neptune Road to Bennington Street, with a right turn onto Bennington Street marking the beginning of Route 145. Route 145 travels northeast along this major arterial street to the Orient Heights neighborhood and then bears right along Saratoga Street at Orient Heights Square. The route continues along Saratoga Street east until crossing into Winthrop over a bridge at Belle Isle Inlet.

Route 145 travels a short distance down Main Street in Winthrop before turning right and traveling nearly due south along Pleasant Street. This residential section of Winthrop features Donovan's Beach which offers a view of the Boston skyline looking west-southwest across Logan Airport. Pleasant Street continues south then bears left a few times before becoming Washington Avenue, where Route 145 travels east to meet Veterans Road. At this intersection, Route 145 heads north along Veterans Road while traffic heading for Point Shirley and Deer Island continues to Shirley Street. Along Veterans Road the route heads north through Winthrop and then bears left at the intersection with the north end of Winthrop Shore Drive to become Crest Avenue and then Revere Street, heading generally northwest.
