Sasanian roads were physical infrastructure important to the maintenance and development of the Sasanian Empire. Much of the Sasanian road system remains unknown due to minimal archaeological investigations.^[1] What can be deduced derives from the work of later Islamic geographers, such as Ibn Khordadbeh, who in turn relied on information provided by merchants.^[1] The main Sasanian road started from Mesopotamia.^[1] One northern route went through Hatra and Nahavand towards Khorasan, Tokharistan and Transoxania.^[1] Another northern road went to Armenia and Lazica through Adurbadagan.^[1] A southern road went through Dehloran and Susangerd towards Khuzestan before eventually reaching Pars by following a coastal road along the Persian Gulf.^[1] All roads of the Sasanian Empire were served by toll-stations, which taxed commercial goods, and services were offered to travellers as well, although the historian Khodadad Rezakhani notes that the "extent of these is not apparent archaeologically".^[1]
