Arterial roads in Oman

Arterial roads in Oman are important roads which connect cities and national roads together. They form the second highest category in the Omani route numbering system and are designated with route numbers beginning with "A", from A1 to A13

The arterial road system was established on December 18, 2019 by the Ministry of Transport (now the Ministry of Transport, Communications and Information Technology), through the Road Numbering and Classification Guide. The guide outlined thirteen arterial roads detailing their official classification, names, start and end point and distances.
