Project Benefits

Completion of the Dalry Bypass will encourage improved economic and employment opportunities through better journey time reliability for motorists and businesses along the length of the A737. In addition, the Dalry Bypass will help separate local from strategic traffic and lead to improved safety for both rural road users and communities.

Impact during construction

Engaging with local communities is at the heart of all of Transport Scotland’s major construction projects and will continue to be vital as work progresses on constructing the A737 Dalry Bypass.

The Contractor has a dedicated Community Liaison Officer (CLO) who is committed to keeping the local community informed as the project progresses.

Please contact the CLO for any enquiries relating to the construction of this project:

Traffic management

As most of the construction work will take place off-line, it is anticipated that traffic management will be predominantly limited to periods when the connections of the bypass to the existing A737 trunk road are being built. There will be occasional restrictions/closures which will be advertised locally by road signs.

We will make every effort to minimise disruption where possible, however road users should expect some disruption to the traffic flow and should allow additional time for journeys.

Road users are advised that the following traffic management will be in place but should note that the dates given are as accurate as possible but are subject to change at short notice:


  • A 40mph speed limit and a no overtaking section will be in place to ensure the safety of both road users and the construction team.
  • 2 way temporary traffic signals will be in operation on the A737 between Pasturehill Cottage and Highfield  from 10am on 9 April continuously until 1pm on 13 April to undertake public utility diversionary works.
  • 2 way temporary traffic signals will be in operation on the A737 at various locations between the Railway Bridge and the Den during the night from 29 April to 11 May to undertake public utility diversionary works.


  • A 40mph speed limit will be in place on a section of B707 between the junction of the C99 and A737 near Coalheughglen Farm from 26 October 2017 for approximately 6 months to ensure the safety of both road users and construction team.

Blair Road

  • Blair Road in Dalry will be closed between Baidland Avenue and the C99 from Friday 13 October 2017 for approximately 6 months. Diversion signs will be in place.

The closure is to allow construction of the new Blair Road Overbridge.


There will be a road closure on the C99/B707 from A737 to Blair Road commencing on 14 May and lasting approximately 3 months.  Diversion signs will be in place.

The closure is to allow the construction of a new roundabout at Highfield.

Working hours

The working hours on-site are Monday to Saturday from 7am to 7pm. There may, on occasion, be a need for work to be carried out on Sundays. 

Environmental impact

An environmental impact assessment was undertaken and the Environmental statement was published along with the draft Statutory Order material.
