A338 Bournemouth Spur Road background and funding

Bournemouth International Growth Programme logo

The Dorset Local Enterprise Partnership (DLEP) has secured funding from Government for a five year programme to improve access to South East Dorset including Aviation Park, which is a key site capable of delivering significant economic growth.

To release the full potential of Aviation Park and the surrounding land, five major highway schemes have been identified for substantial improvement to increase their capacity, reduce congestion and improve journey times between Bournemouth Airport, Bournemouth town centre and the wider road network.

The five DLEP schemes as part of the Bournemouth International Growth Programme (opens in a new window) are:

  • A338 Spur Road improvements
  • Chapel Gate improvements
  • Hurn Roundabout improvements
  • Blackwater Interchange improvements
  • Conurbation-wide key junction improvements including:
    • Bear Cross Roundabout
    • A338 widening from Cooperdean to Blackwater Junction
    • Longham mini-roundabouts
    • Mountbatten Junctions

The first scheme will be a reconstruction of the A338 Bournemouth Spur Road. It carries around 59,000 vehicles per day of which 3.7% (2,200 vehicles) are HGVs, which makes it Dorset's most heavily trafficked road. It was built in the late 1960s and the construction of the road is failing due to its age and the volume of traffic it carries.

Although Dorset County Council has undertaken major maintenance works during the past 12 years on limited sections of the northbound carriageway, these have only provided a short term solution to a longer term problem - the rate of deterioration has overtaken the rate at which the road can be maintained with pothole repairs, patching and crack sealing.

The A338 major maintenance scheme will:

  • Unlock the potential of key employment land to support critical business sectors, creating more jobs, retaining skills and delivering economic growth and prosperity for Dorset
  • Improve  journey time reliability on the A338 Bournemouth Spur Road
  • Remove the need for the disproportionate level of non cost effective pothole repairs, patching and crack sealing maintenance
  • Provide a safer transport corridor and remove collision clusters
  • Reduce traffic noise

The proposals are supported by Dorset County Council, Bournemouth Borough Council, Borough of Poole, Christchurch and East Dorset councils, businesses, transport operators, Bournemouth Airport and the Dorset Local Enterprise Partnership (opens in a new window).
