Two other sections of modern Route 28 were also parts of early turnpikes. The section between Middleborough and Bridgewater, where Route 28 overlaps with Route 18, was part of the New Bedford and Bridgewater Turnpike. The portion along Blue Hill Avenue, between the village of Mattapan and Franklin Park Zoo, was the northern half of the Brush Hill Turnpike (the lower half is modern Route 138). In Cape Cod, most travel was by water and roads were not improved until late in the 19th century.
