THE Hatfield Tunnel will be shut at night this week for motorists travelling south on the A1(M).

The carriageway will be closed between junctions 4 and 3, either side of the tunnel, as part on the ongoing roadworks.

Closures will be in place from 10pm until 5am each night from tonight (Monday) until Saturday.

A Highways Agency spokesman said: “We are carrying out inspection work inside the tunnel, which is currently being refurbished, as well as making preparations for a change to the road layout.”

A fully-signed diversion route between junctions 4 and 2, using the A1001 and A414, will be in place.

Motorists are advised to allow extra time for their journey.
