Marress Roundabout is a large roundabout on the Northern Approach Road in Irvine town centre which was completed in 1974. It has ample space for a flyover for the A737 which is the only classified road at the junction, but the bridge was never built. When originally opened, it was the A78 which passed through the junction, but this was moved in 1978 onto the Irvine Bypass, and the A737 extended along its former route. The junction has three main arms, each of which is a dual carriageway. The A737 passes through from north to south, with wide flaring between the carriageways to leave space for the flyover. New Street then heads west to the harbour area, and also the car parks for the shopping centre and retail park. All three arms have two approach and departure lanes, with between one and three spiralled circulatory lanes, depending on the volume of turning traffic.
The junction has a fourth arm in the north east corner, serving a row of riverside houses otherwise cut off from the town, and Fullarton Church, which stands to the north west, also has a rather awkward access directly from the roundabout.
