The designs for a section of Aberdeen’s multi-million Berryden Corridor can today be revealed.

The plans have moved forward after an application was made to identify if an environmental impact assessment for a section of the £26.4 million Hilton Road, Ashgrove Road and Great Northern Road, and St Machar Drive needs to be carried out.

The new dual carriageway for the section will be less than 10 kilometres in length.

Some gardens will be bulldozed, while the council has already lodged plans to demolish a group of eyesore buildings it owns on Powis Terrace, including the former Central Garage.

Aberdeen City Council has contacted homeowners who will be affected by the plans.

The overall upgrade would see the existing road widened to a dual carriageway from Skene Square to St Machar Drive roundabout.

Junction improvements will also be made on the route.

The scheme is designed to help traffic move around the city better and work alongside the improvements already delivered by the new Third Don Crossing which opened in June.

A report to planners by Mike Matheson, senior engineer at the city council, said: “The new section of road to the rear of the properties along Great Northern Road will significantly reduce traffic along the front of these properties and will improve the setting of these, including Kittybrewster Primary School.

“However, there will be an impact on some gardens to the rear of the properties.

“As the development utilises the existing road network and brown field development land, the main likely impacts are the effect on: noise and air quality, plus vibration and dust during the construction phase.”

An Aberdeen City Council spokeswoman said: “A screening letter was submitted to Aberdeen City Council’s planning authority as a precursor to submitting a formal planning application.

“The screening exercise is a required step to determine whether or not a full environmental assessment of the scheme is required to be submitted along with the planning application.

“Once the planning authority confirms what requires to be done, work will continue towards formally submitting the planning application in due course.”
