The speed limit on the northbound carriageway of the A3 between the A333 Grayshott junction and the Thursley side of the 1/14-mile Hindhead Tunnel in Surrey has been 40mph for several months, but National Highways is now set to end the restrictions.

The limit was imposed before Christmas as a safety precaution while efforts took place to fix an “intermittent fault” affecting some traffic signals.

The southbound restriction has already been lifted while National Highways are confident of removing the 40mph northbound limit by the end of the month, reports the Farnham Herald.

“We are carrying out final testing of the system before removing the reduced limit by the end of the month,” said a National Highways spokesperson.
