Hill Roundabout

Hill Roundabout is a large roundabout junction on the A736 in the new town of Irvine. It was originally planned as a grade-separated roundabout interchange with Long Drive passing over it on a flyover. It also makes the point where the original planned route of Long Drive deviates from its intended northern terminus at the (unbuilt) Draughtburn Interchange and instead heads northwest to Eglinton Interchange. Today, however, the route is an at-grade six-arm junction between the A736, B7080 and three minor roads. All of the arms are single carriageway, but widen to two lanes on the approaches for turning traffic. There are also two circulatory lanes around what is an unusually large island, obviously built to accommodate the never-built overpass. The southern part of Long Drive is actually a multiplex between the A736 and B7080 as far as Stanecastle Roundabout a short distance to the south.

The proposed line of the overpass, connecting the two parts of Long Drive, presumably means that the B7080 approach is approximately on the line of the proposed northbound onslip, while the A736 follows the southbound onslip. There is still ample space at the junction, and beyond, to complete Long Drive as originally planned with the overpass and sliproads, as the road largely passes through a wide expanse of parkland.
