Work will begin on Saturday 31 May and be completed by Saturday 15 June. The work will be carried out on the northbound carriageway and will take place 24 hours a day.
Highways Agency Project Manager Kyle Maylard said:
We will be working round the clock to carry out the work quickly and to minimise any disruption to drivers. A 50mph speed restriction will be in place during the work for the safety of drivers and road workers.
During the work the northbound carriageway will be closed and traffic will be in contraflow on the southbound carriageway. The A167 Topcliffe northbound entry slip road and B1448 Thirsk northbound exit slip roads will be closed. Traffic wishing to enter or exit the A168 at these slip roads should follow the clearly signed diversion route via A168 northbound, A168/A19 York Road Interchange, A170 to Thirsk then follow existing signs.
