Drivers are being warned about a series of overnight closures on the A66 and A1(M) in County Durham and North Yorkshire for maintenance and electrical works.

National Highways has announced a number of temporary overnight road closures affecting parts of the A66 and A1(M) later this month and in June.

On the A66 near Long Newton Interchange in County Durham, several slip roads are due to close for two nights from May 26 between 10pm and 6am while horticultural works are carried out.

The closures will affect both eastbound and westbound entry and exit slip roads linked to Long Newton Interchange, including routes connecting the A66 with Darlington Road and Mill Lane. Signed diversion routes will be in place during the works.

National Highways has also confirmed overnight closures on the A1(M) near Blackwell Spur in County Durham.

The westbound carriageway between Blackwell Spur Interchange and Junction 57 is scheduled to close at times between 8pm and 6am on May 27 while technology works are completed. Diversions will operate throughout the closure.

Further overnight restrictions are planned on the A1(M) in North Yorkshire on June 17.

The southbound carriageway between Junction 51 at Leeming Bar and Junction 50 at Baldersby Interchange will close overnight between 8pm and 6am for electrical works. Southbound entry and exit slip roads at the two junctions will also be affected.

National Highways said all closures would be clearly signed and would not apply to emergency service vehicles or vehicles connected with the works.
