tremont street begins at government center in boston's city center as a continuation of cambridge street, and forms the eastern edge of boston common. continuing in a roughly southwesterly direction, it passes through boston's theater district, crosses the massachusetts turnpike, and becomes a broad boulevard in the south end neighborhood. it then turns to the west as a narrower four-lane street, running through mission hill and terminating at brigham circle, where it intersects huntington avenue. the street name zigzags across several physical roads, often requiring a sharp turn to remain on the street.
