A585 Bypass Project in Lancashire Sets Benchmark with 18.2% Biodiversity Net Gain

A landmark National Highways scheme in Lancashire is setting new standards for environmental stewardship, with the completion of extensive ecological enhancements along the A585 Windy Harbour to Skippool bypass.

The final phase of landscaping has seen a staggering 360,000 plants — including over 72,000 trees and shrubs — introduced across the three-mile route. This initiative has delivered an impressive 18.2% biodiversity net gain, well exceeding the government’s ‘no net loss’ mandate and creating an environmental legacy set to benefit generations to come.

Dan Moore, National Highways Project Manager, commented:

“This scheme has gone above and beyond environmentally, not only meeting but surpassing our biodiversity objectives. Achieving an 18.2% net gain is a significant milestone, and a powerful testament to the dedication of every team member involved.

Our projects aren’t solely about improving connectivity; they’re about delivering lasting value — enhancing the local environment and improving quality of life for communities along our network.”

Officially opened last year, the bypass was designed to alleviate longstanding congestion issues around Little Singleton. The new route diverts traffic away from the heavily burdened Mains Lane, easing bottlenecks and improving journey reliability towards Fleetwood, while also supporting regional economic growth.

But its benefits extend far beyond traffic flow. As part of the scheme’s comprehensive environmental package, the project has introduced new woodland areas, species-rich grasslands, and constructed ponds to support local biodiversity. Wildlife crossings beneath the carriageway and designated bird mitigation zones have also been incorporated, reflecting a nature-first design philosophy.

In parallel, Mains Lane has undergone safety upgrades to better serve pedestrians, cyclists, and equestrians — reinforcing the project’s commitment to sustainable, multi-modal transport infrastructure.

Delivered by National Highways in partnership with Kier, the project team has also invested in community engagement programmes focused on environmental education and local enrichment. These initiatives have cemented the bypass as not just a transport upgrade, but a symbol of responsible infrastructure development.
