A1(M) Hatfield Tunnel: full overnight closures

Road users are advised the northbound and southbound carriageways of the A1(M) Hatfield Tunnel will be closed overnight for five nights from Monday 11 October to Friday 15 October 2010 inclusive for ongoing tunnel refurbishment work to be carried out.

The work will take place between 10pm and 5.30am (Monday to Thursday) and 11pm to 6:00am (Friday) when traffic flows are lower, to reduce the impact on road users.
