The AWPR/B-T project will bring substantial benefits to the whole of the north east of Scotland. This includes reducing congestion, improving journey times, cutting pollution in the city centre, boosting the economy, improving road safety and enhancing public transport.

Economic growth

Once complete, the AWPR/B-T will boost the north east economy by:

Generating income

The combined impact of increased sales and reduced costs across the key sectors is estimated to be more than £6 billion in the north east. It is also expected that in excess of 14,000 jobs will be created over the next three decades.

Enhancing Business Competitiveness

It is anticipated that AWPR/B-T will improve business competitiveness and stimulate investment by:

  • Enhancing market conditions for key sectors including oil and gas exploration, fishing and tourism and helping to retain and attract jobs in these sectors
  • Providing a guaranteed fast-link for freight and goods from the north east to markets in the south
  • Reducing business costs caused by congestion and inconsistent journey times, such as extra fuel and driver costs
  • Revitalising the Buchan area and protecting and growing economies in towns such as Peterhead and Fraserburgh
  • Attracting more people to work and live in the north east by expanding labour catchment areas and providing less stressful commuter journeys
  • Developing industrial sites on the periphery of the city which are not currently viable due to poor transport links
  • Improving access to the city centre and the area as a whole for residents, shoppers and tourists
  • Enabling other elements of the Regional Transport Strategy to be completed, such as rail projects and ‘Park and Choose'

Additional income of £105 million from new business investment is forecast over the 30 years following completion, with 600 jobs forecast to be created as a direct result.

Five years after completion: 

  • The Food and beverages industry will increase sales by 1% and reduce costs by 5% 
  • Non-food manufacturing will increase sales by 1.3% and reduce costs by 2.5% 
  • Retail will increase sales by around 5% and reduce costs by 1.7% 
  • Tourism will increase sales by 5.6% and reduce costs by 2.5% 
  • Haulage and distribution will reduce costs by around 3.3% 
  • Business services will reduce costs by around 5%

Reduced congestion


In the first year of opening, the number of vehicles using key points in Aberdeen is expected to be reduced by thousands:

  • 8,600 (31%) on the A90 North of Stonehaven
  • 4,500 (26%) on the Parkway
  • 2,900 (26%) on the A93 (at Milltimber)
  • 8,300 (22%) on Anderson Drive
  • 8,800 (20%) on the A90 North Anderson Drive approaching Haudagain roundabout
  • 6,800 (14%) at A96 Auchmill Road west of Haudagain roundabout
  • 5,600 (14%) on the A90 at Bridge of Dee roundabout
  • 5,600 (14%) on the A956 (River Don)

Thousands of vehicles are also expected to be removed from rural roads, which are unsuitable for high volumes of traffic. In the first year of opening, there will be an estimated reduction of:

  • 12,700 (74%) between Kingswells to Newhills / Bucksburn road
  • 5,700 (93%) between Peterculter and Elrick (B979)
  • 3,400 (72%) on Netherley Road (B979)

Daily reductions in goods vehicles

It is anticipated that the route will also remove a substantial number of heavy goods vehicles from key existing routes and rural roads in the first year of opening: 

  • 82% on the A93 (Milltimber)
  • 23% on the A96 (Auchmill Road)
  • 12% on the A944 (Kingswells)

Goods vehicles are expected to be removed from a number of key locations on the A90:

  • 36% at Denmore
  • 32% north of Stonehaven
  • 30% at North Anderson Drive
  • 28% at Anderson Drive, 
  • 23% on the A956 (River Don)
  • 21% at King George VI Bridge

Balmedie to Tipperty

Once the new B-T section opens in spring 2017, the majority of the existing A90 between Balmedie and Tipperty will become part of the local road network. The traffic flows on this road will significantly reduce, catering mainly for local traffic. 

Estimated daily reductions on the existing A90 (to become local road):

  • 23,100 (97%) vehicles north of Balmedie will be transferred to the new A90
  • 18,700 fewer vehicles (95%) north of the A975 junction on the existing A90

The traffic on the B977 is also expected to reduce by approximately 80%.

Journey times

Reducing journey times will improve the quality of life for individuals and help to retain and attract businesses that need reliable infrastructure to grow. 

The table below provides examples of how typical journeys are estimated to be improved:

Stonehaven Dyce 55 mins 28 mins 27 mins (49%)
Ellon Portlethen 60 mins 38 mins 22 mins (36%)
Peterculter Bridge of Don 45 mins 24 mins 21 mins (46%)
Cove Kirkhill 43 mins 23 mins 20 mins (47%)
Westhill Altens 36 mins 26 mins 10 mins (28%)
Bridge of Don Altens 29 mins 19 mins 10 mins (35%)
Improving safety 

Following the construction of the AWPR, it is expected that there will be a net reduction of one fatal, nine serious and 72 accidents every year because the road:

  • is a custom-built strategic trunk road using best practice in road design
  • will reduce the overall level of traffic using urban roads
  • will reduce traffic levels on unsuitable rural roads 
  • will decrease stress levels as a result of reduced congestion

 (See Source: Note 1Note 5 and Note 6


Overall, some 75,000 properties will benefit from improved air quality as a result of the AWPR. This will be achieved by taking slow-moving traffic away from city streets and cutting vehicle build-up at junctions. It has been scientifically proven that free-flowing traffic generates lower carbon emissions.

Improvements in air quality, along with reductions in traffic volume, will make pedestrian and cycle travel around Aberdeen easier, safer and a more enjoyable experience. The existing A90 will also become safer for use by cyclists, pedestrians and equestrians as the levels of traffic will significantly decrease.

Plans for the full or potential pedestrianisation of Union Street and Broad Street will also be assisted by the route.

Public transport


The AWPR/B-T is a key part of the Modern Transport System and will enable improvements to be made to public transport:

Park & Ride

The AWPR will enable better links to existing Park and Ride facilities at Kingswells, Ellon and Bridge of Don. It also provides an opportunity to create additional Park and Ride sites in the south of the city near Wellington Road, in the West at Chapelbrae and in the north on the A947 Newmachar Road.

Bus Journeys

Anderson Drive is currently the main trunk road for traffic heading round Aberdeen and priority is given to traffic travelling north and south. The AWPR will become the main trunk road, diverting traffic away from Anderson Drive. 

This will free up Anderson Drive and connecting roads for more public transport and enable greater priority to be given to traffic, in particular buses, heading into and out of the city. This will speed up journeys and improve reliability and frequency of services.

The table below shows how some public transport journeys will be improved:

A956 North 29 mins 25 mins 4 mins (13%)
A956 South 28 mins 24 mins 4 mins (16%)
A944 23 mins 21 mins 2 mins (9%)
A93 39 mins 37 mins 2 mins (8%)

Air Services

The AWPR will provide a fast, direct link to Aberdeen Airport increasing the airport's catchment area and potentially leading to inward investment including new airlines and routes coming to the city.
