In the 1970s, Tel Aviv University professors Israel Roll (archaeology) and Benjamin Isaac (ancient history) surveyed the Roman roads here and produced a map of their finds. The map bears a striking resemblance to the layout of roads we use today, but now a great change is taking place: Israel's new roads don't follow the network that crisscrossed the country for two millennia.For more on Roman roads and milestones, see here and links, plus here, here, here, and here.The most obvious reason, as Hebrew University geography professor Rehav Rubin says, is that until 50 years ago, when road-construction technology allowed for leveling, tunneling and excavating, natural topography dictated the route. Now that routes can be shortened by blasting and tunneling through mountains and/or leveling steep grades, the topography issue is almost a thing of the past.
