On second-century developments, see the essays in Sepphoris in Galilee, several of which address this topic. For detailed discussion of a monumental road and a reference to the agora, see C. Thomas McCollough and Douglas R. Edwards, “Transformation of Space: The Roman Road at Sepphoris,” in Archaeology and the Galilee, ed. Edwards and McCollough (Atlanta: Scholars Press, 1997), pp. 135–142.
