Holmston Roundabout lies on the Ayr Bypass and is where the A70 crosses the A77. The roundabout was built slightly offline from the A70, which dipped a little to the south just here, as can be seen by the hedge line to the south west of the junction. The junction is a fairly ordinary 4-arm roundabout, with 2 approach lanes from each direction. The only additional feature is that the southern arm of the A77 is S4 to start with, dropping to S2+1 to accommodate a southbound climbing lane. To the north, the A77 bypass crosses the River Ayr, whilst the A70 crosses east-wets, roughly at right angles.
