|Route outline (key)|
The A737 is now the Glasgow - Irvine/North Ayrshire trunk route. It lost several miles to the A761 Paisley Road West between Glasgow (A8) and Paisley, but eliminated the A740 from the maps completely.
Glasgow Airport - Irvine
The A737 starts at the St James Interchange near Glasgow Airport. Good (if bumpy) dual carriageway for the first few miles, bypassing Johnstone, then at the B787 interchange at Kilbarchan it becomes single carriageway! The rebuilt road stops soon after, and is not too good from here on to Kilwinning. The A760 departs for Largs at an unusually shaped roundabout, and Beith is bypassed by a very old looking bypass with some bad crossroads. Dalry is not bypassed, so the A737 meanders through here on its way to Kilwinning where, at a traffic light controlled T junction, the A738 takes the trunk road E to the A78, and the A737 turns left (east) through Kilwinning on the old A78, then south through Irvine, passing the W end of the A71 before ending at the Newhouse Interchange.
The Section from the M8 to the A761 was originally built as A740. The A737 started on the A8 in Kingston, Glasgow, although the end was moved to Ibrox in the 1960s when the A8 was routed away from the riverbank and docks.
