The junction 47 upgrade on the A1(M) near Knaresborough cost £3.1 million more than budgeted, it has finally been revealed.
North Yorkshire Council said this week the scheme, which was forecast to cost £7.7 million, actually cost £10.8 million.
The project finished in April last year, seven months later than planned.
North Yorkshire County Council, which was abolished on April 1 this year, said last year costs had increased to £10m.
But no figure had been given since despite requests from the Stray Ferret. The council said this was due to ongoing discussions with contractors over the final amount.
But following our latest enquiry, Cllr Keane Duncan, North Yorkshire Council’s executive member for highways and transport, said:
“The final costs are £10.8 million. This includes the additional costs for delays which were caused by the discovery of the protected great crested newts, as they legally had to be relocated.
“We also experienced poor ground conditions on the southbound slip road, and during the coronavirus pandemic operatives had to comply with strict health and safety guidance which extended the timescale.”
“The Junction 47 upgrade has proved hugely successful, meeting the high traffic volumes without delays at peak times including during the Great Yorkshire Show.
“It was voted the winner of the best large projects award at the CIHT Yorkshire andHumber awards in October 2022.”
Three of the four slip roads onto and off the roundabout were widened to increase capacity.
Traffic signals were installed on the roundabout to improve traffic flow and lights were added to the T-junction between the A168 and the A59, a short distance from junction 47 on the York side, to benefit drivers turning onto the A59 and to improve safety.
To the west of junction 47, between the A1 and the Flaxby roundabout, a lane was added for traffic travelling east, so there are now two lanes in each direction between those two roundabouts.
