Preparation works underway at Haudagain Bottleneck

Haudagain-Bottleneck

Soil Engineering have started vital ground investigation work for the £186k A90 Haudagain Improvement Scheme and Scottish Transport Minister Keith Brown was on hand to see the start of the works. The ground investigation will provide the detailed information needed for the development of the scheme.

Plans to improve the notorious Haudagain roundabout, the junction between the A90 and A96 trunk roads in Aberdeen, with a new dial carriageway link went on show earlier this year. The roundabout at the bottom of Anderson Drive is a bottleneck and the junction between several major roads in Aberdeen which is currently operating over is capacity. This causes significant queues and delays to traffic on all the approach roads.

Public exhibitions were held by Transport Scotland in Aberdeen in April this year which gave the public the opportunity to view the preferred option for the Haudagain Improvement Scheme.

Mr Brown said “Having let local communities view and comment on the scheme’s preferred route earlier this year, we are now starting the vital ground investigations which will give us the greater level of information we need to help shape the scheme’s design.”

Soil Engineering expect to complete the site works for the scheme by the end of the year. This will be in good time for the next stage of the scheme; the specific design proposals for the road, which are expected to be published next summer.

Tristan Llewellyn, Director of Soil Engineering Geoservices Ltd said:

“We are delighted to be taking forward this ground investigation work for the A90 Haudagain Improvement scheme. We have worked extensively on the Aberdeen Western Periphery Route with Transport Scotland and Jacobs over the past 10 years and we welcome this opportunity to further assist in the alleviation of Aberdeen’s congestion”

“We look forward to working with Transport Scotland over the next few weeks as we play our part in delivering this scheme for the people of the north east of Scotland.”


Soil Engineering are programmed to be on site for a period of 6 weeks and will complete the works using:

2 No. Cable Percussion rigs
1 No Terrior unit
1 No Buretta Rotary Rig

And at peak a field staff of 12 geologist, geotechnical engineers and drilling specialists.

The Clients Engineer, Jacobs UK Limited designed a phased approach for the works to maximise the benefits and value of the investigation, allowing dynamic development of the scope of works as the various ground conditions became apparent.

Work on the Haudagain A90 bypass will not get under way until 2018 when construction of the Aberdeen bypass is complete.

Soil Engineering are completing the A90 Haudagain Scheme in parallel with works they are currently undertaking on the A9 Dualling: Birnam to Tay Crossing Ground Investigation, also for Transport Scotland.
