Leaving Winthrop, Route 145 enters Revere and is called Winthrop Parkway, which travels north along the Atlantic Ocean past Revere's Beachmont neighborhood and meets Revere Beach Parkway at Eliot Circle.
The road then goes through the center of the Orient Heights section of the neighborhood and curves left past the Belle Isle Marsh Reservation on the right, entering the city of Revere and ending in Beachmont Square at the intersection of Winthrop Street and State Road.
