The account cautions against treating the Dark Ages or medieval period as an infrastructure void after the Roman period. Roads were built, bridges were maintained, and older surfaces were renewed. The important difference was coordination: local lords and merchants usually pursued particular links rather than a national plan. Over time, many point-to-point improvements accumulated into wider networks. The passage distinguishes missing central strategy from missing technical effort, a useful caveat when connecting transport geography to military and economic development.

Medieval road building was local, not absent
Post-Roman Britain still built and maintained roads and bridges, but local lords and merchants lacked the national coordination of later transport systems.
