1. A more comprehensive map system. Like any other construction, roads will require a fair bit of advance planning to actually be useful and efficiently built. This is not possible without the option to create larger maps that encompass an entire region.
2. Some level of security for both the people using the road and the road itself. Even if fast travel over long distances is convenient, no one is going to use roads if they have a high chance of getting you killed. Likewise, no one is going to bother with building roads in the first place if any random wannabe troll kid can vandalize them with impunity (since how does one claim the entire area covered by a long-distance road?).
3. The majority of the materials used to construct the road itself being plentiful and/or renewable. Since a long, well-maintained road is a powerful tool, I don't think anyone would complain if they required some reasonably valuable materials like steel or wrought iron at the starting point and ending point; the issue is if actually extending the road takes large amounts of non-renewable materials like stone. It might be less of a problem if you could at least lift and transport boulders.
