 The new expressway relieved congestion along US 6 and Route 28 in the Buzzards Bay business district, greatly reducing the number of accidents along the approach to the Bourne Bridge.In 2007, MassHighway completed a renumbering of the three interchanges along the length of Route 25 as part of a signing upgrade project.Previously, the I-195 interchange had been numbered Exit 1 as part of I-495's numbering scheme, with the Onset interchange also being Exit 1 as part of Route 25's own scheme.
