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 close to Pasturehill Cottage from 6am on 4th June to 1pm on 7th June continuously for public utility diversion work.


  • Sections of the C99 and B707 will be temporarily closed to all road users, including cyclists and pedestrians at Highfield from 14th May for approximately 3 months. Diversion signs are in place. The National 7 Cycle Route has also been diverted with diversion signs in place. This closure is to facilitate the construction of a new roundabout at Highfield.

Girder Deliveries

  • Over the period 26 April to end July 2017 a large number of girder elements will be delivered by lorry to the Dalry Bypass construction site on the A737 at Hillend. During this time a number of deliveries will be made by wider lorries which will be accompanied by an escort vehicle. Delivery of these girder elements are essential to construct the Dalry Bypass. We apologise for any inconvenience caused.

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.

Preferred route option public exhibition
