The Dalry Bypass was a road scheme to construct a bypass of the town of Dalry in North Ayrshire on the A737. From the south end, it starts near Hillhead Farm on the existing A737. A new roundabout was formed here (Hillend Roundabout), then the new road heads north east on a new viaduct crossing the River Garnock and railway line. From here the road passes south of Blairland Estate, where it is crossed by an overbridge carrying the C57 Blair Road.
At the north end of the town the road meets the original route of the A737, now B714, and B707 at the new Highfield Roundabout and continues a short distance past Highfield and Birkentop Farm to realign the road away from these settlements.
Construction stated in July 2017 by a joint venture contractor of Farrans and Roadbridge; the project, which cost £31.2 million, officially opened to traffic on 30 May 2019, seven months ahead of schedule.
