It connects the Dammam metropolitan area to the industrial area of Ra's al-Khair, running in the north-south direction for its entire length from Khobar in the south to the Ra's al-Khair north of Jubail, while providing access to Saihat, Qatif and Jubail along its length.

Being a major secondary intercity route in Saudi Arabia, Route 613 consists of three traffic lanes and an emergency lane on each side, with both sides separated by a median strip, for a total of eight lanes. All intersections on the route are grade separated, and it runs parallel to the Persian Gulf for its entire length and is connected to other major highways in the region, along with Highway 40.
