|Route outline (key)|
The route has its northern terminus on the A8 at the Braehead shopping centre on the edge of Renfrew. It heads south, crossing under the M8 at Jct 26, then through Hillington Industrial Estate, crossing the A761 Paisley Road and meeting the B762 at a traffic-light-controlled T-junction in Roughmussel, where it turns right. Next it crosses the main A726 at a signalised staggered crossroads and heads southwest through Barrhead.
The road follows the Glasgow to Kilmarnock railway line, crossing it once, as far as Lugton, where the A735 bears off to the left, taking the railway with it. The road continues, with several B-roads turning off on both sides, until it turns off onto the Girdle Toll bypass on the edge of Irvine. Unusually, no intersection on the A78 Irvine bypass was built for the A736, so to head north or south the B7080 has to be followed. After going over the A78, the A736 continues into Irvine. It TOTSOs right to avoid the pedestrianised town centre, then turns right at a mini-roundabout onto the old A78 to end at traffic lights on the A737.
The A736 originally started on the A77 in the Shawlands area of Glasgow. It ran through Pollokshaws to reach its current route at the present A736 / B762 junction in Roughmussel. This section starts off unclassified but then becomes the B769 and then the B762.
