The A737 Dalry Bypass comprises approximately 3.5km of single-carriageway new trunk road to the east of Dalry town in North Ayrshire.
The bypass aimed to reduce delay and congestion within Dalry and improve road transport links to Glasgow and Ayr. The A737 links with the M8 motorway at Paisley.
As part of the scheme, a new junction was required to the north and south of the town on the existing A737 trunk road.
A significant major bridge structure was required to carry the new bypass over both the Glasgow to Ayr Railway Line and the River Garnock and its flood plains at the southern end of the scheme.
The multi-span arrangement of the structure was selected to be sympathetic to the surrounding landscape and topography and to minimise any environmental impacts.
