A737 Dalry Bypass

Scheme outline

The aims of the scheme are to improve journey times on the A737 between Glasgow and North Ayrshire, and to relieve congestion in the town of Dalry.

The proposed new single carriageway road will leave the existing A737 near Highfield, to the north-east of Dalry. The road will then pass to the east of the town, crossing the Glasgow to Ayr railway line and the River Garnock, before re-joining the existing A737 near Hillend Farm to the south.

Following a public local inquiry and hearing sessions conducted in 2014, the Scottish Government made the orders for the scheme in December 2015 and included a funding package within its draft budget for 2016/17 published on 16th December 2015. The budget was subsequently approved in February 2016.

The scheme then went out to tender in March 2016 with a shortlist published by Transport Scotland in July 2016. The shortlisted bidders are Balfour Beatty Civil Engineering Limited, Farrans Construction and Roadbridge, Interserve Construction Limited and John Paul Construction Limited / Somague Engenharia.

The winning bidder will be appointed during early 2017 with work due to commence prior to the end of March 2017 and completed by Autumn 2018.
