Two of three new A59 Kex Gill carriageways open before the end of August, replacing a landslip-hit route with £6m in repair costs after 15 landslips.
Sisk Infrastructure completed the main construction works on the A59 realignment at Kex Gill, clearing the way for the majority of the new route between Harrogate and Skipton to open in the coming weeks. North Yorkshire Council has programmed two of the three new carriageways to carry traffic before the end of August. The remaining work covers tie-ins to the existing road network and the final road markings.
The 4.2km route replaces a stretch of road that has closed repeatedly since 2000. The existing A59 at Kex Gill has suffered 15 landslips in that period, and North Yorkshire Council says the repair bill has reached more than £6 million. Each closure forced long diversions for communities and businesses.
Lauren Luck, regional engineer at Sisk Infrastructure, said the site had required solutions to difficult ground while protecting the landscape.
"The project has presented significant engineering challenges, which our team and supply chain partners have successfully delivered solutions in very difficult terrain with significant environmental considerations to manage," Luck said.
Malcolm Taylor, North Yorkshire Council's executive member for highways and transportation, called the opening of the main section a landmark moment for the county. He said the old road had been vulnerable to landslips for decades, and the replacement was designed to serve the area "for generations to come."
Work continues on the final eastern and western connections to the existing network, including a redesigned junction at Church Hill and access improvements around Fewston Reservoir. The council said these tie-ins are the last major items before the route opens.
The scheme's environmental measures include more than 12,700 native trees, wildflower planting, habitat creation and balancing ponds. New pedestrian and cycling routes and a bridleway for horse riders have been added, along with 4km of natural stone walls designed to fit the Nidderdale National Landscape.
Once the connections are in place, the realigned route will move traffic off the landslip-prone section of the old A59 and provide a more reliable connection between Harrogate and Skipton, the council said.
