Searching for articles on wagon-construction in roman times, a much referred hit is Dr. Judith A. Weller et al. on the “Roman Traction System“. It is an article on www.humanist.de, but so far the only article here related to roman wagons and land-transportation. A lot of pages concerning the roman empire has a link to this article. Now I’ve made this link, too.
The article is most concerned on the traction systems, but it has a chapter on wagon-construction, which, besides a few errors, is interesting reading. Including good pictures.
