Route 28 itself is no longer utilized as a long distance through route because of the opening of several parallel expressways along the Route 28 corridor since the 1950s. Interstate 93 serves the Route 28 corridor north of Boston, while the combination of Route 24, the southern end of Interstate 495, and Route 25 serves the corridor south of Boston to the Bourne Bridge. The construction of Route 25, in particular, resulted in a reconfiguration of the connection from the Bourne Corners traffic circle to the Route 25 expressway.
