Wm,
Too true, the Appian Way is still going strong (although maintenance funds are short as usual). Vicenza has some beautiful examples of Roman Construction (to include roads - the trainstation there has a nice example). Mosul/Ninevah Iraq has some amazing examples of Assyrian Construction.
A fun non-mathematical read is 'Roman Roads and Aqueducts' by Don Nardo (ISBN 1-56006-721-7) one in the 'Building History Series' books by Lucent. Mr. Nardo touches upon Assyrian Aqueducts in this book as well. The Dioptra is certainly not a GPS or Total Station but those old surveyors and engineers did some amazing things with them.
Regards,
Steve
