The Project
Work started on 2 September 2006 on a £120m major improvement scheme to reduce congestion and improve journey time reliability on the A2/A282 at Dartford.
It included new roads linking the northbound A282 and the eastbound A2, new lanes on the A2 westbound for traffic joining the M25 going south, and a fourth lane in each direction on the A2 between the M25 and Bean junction, a distance of approximately 1.2 miles (2 kilometres).
Two new viaducts have been built alongside Littledale Viaduct and a flyover over the A2 and M25. There is improvement to drainage and a reduction in noise pollution from using a low noise road surface.
Scheme Objectives and Benefits
- Improved journey time reliability and safety - The construction of the free flow link roads has removed about 40% of vehicles using M25 Junction 2, releasing additional capacity, reducing congestion and improving journey time reliability and safety.
- Reduced noise - A noise reducing surface has been used on all roads.
- Improved local environment - Landscaping included new hedges, dense forest and low screen planting and ground remodelling to integrate the new junction and roads into the existing landscape.
One Year After Opening study
As part of our ongoing programme of Post Opening Project Evaluation (POPE) this scheme has been reviewed at one year after opening. The study compares the outturn effects of this scheme to the predicted impacts. A summary of the five year after report is available to download here: A2/A282 Dartford Improvement and M25 J1b-3 widening Summary Report (PDF 82KB)
