Motorists travelling between Ripon and Boroughbridge face a month of disruption when repairs to a broken culvert take place.
Temporary traffic lights have been in place on the B6265 since late last year when the culvert collapsed and now North Yorkshire County Council says the road will be closed from Friday, March 14, with repair work scheduled to take four weeks.
A spokesman for the council said: “North Yorkshire Highways first became aware of problems at this location on October 23. It was necessary to introduce a temporary traffic control immediately in order to ensure the safety of highway users.
“Inspections revealed that a completely new culvert was required and we immediately began the process of securing funding, preparing a design, and procuring the contract.
“The work entails removing the old brick culvert and replacing it with pre-cast box culvert units/wingwalls and headwalls, and some road reconstruction.”
The B6265 will be closed between the junctions of Ray Lane and Pasture Lane.
A signed diversion for all lorry and major traffic will be via the A61 and A1(M). Local traffic and non-motorised vehicles will be signed via local roads Pasture Lane and Skelton Lane.
The council says it is fully aware of the events at Newby Hall in mid-April and the start of the race season at Ripon Racecourse and will endeavour to have the road re-opened before these events take place.
The council spokesman added: “The work will begin on Friday, March 14, and is scheduled for completion on Friday April 11.
“North Yorkshire Highways apologises for any inconvenience, but the safety of highway users is of paramount importance.”
Progress on the damaged culvert has been welcomed by county Coun Peter Horton (Ripon South) who says he has been contacted by concerned members of the public wondering what was happening with the road after months of temporary traffic lights.
“There will be relief work is going to start because nobody knew previously why there were lights there,” said Coun Horton.
“There has been concern about a lack of action. One person told me if you are going to work early when there’s more traffic about it can take some time to get through.”
