A section of road in Cumbria is to become the responsibility of the local authority as the final part of a "detrunking" programme.
Cumbria Highways takes over a six-mile (10km) stretch of the A65 in April.
It will have to deal with improvements and maintenance from Junction 36, near Milnthorpe, to the county boundary with Lancashire near Kirkby Lonsdale.
The A5092, A596 and A7, together with parts of the A590, A595, A6 and A69, have already been transferred.
Detrunking means that responsibility moves from the Highways Agency to the individual highways authorities.
