Cornwall Council
Section 14(1) of the Road Traffic Regulation Act 1984 (RTRA 1984)

Notice is hereby given that Cornwall Council is under the above order dated 28th July 2025 continuing to prohibit the use by traffic over an area of highway as defined in the schedule below.

The Order which commenced on the 16th August 2025 and is currently in force for eighteen months will now continue until the 1st March 2026.

The prohibition will be in force 24 hours a day, weekends included The Council is satisfied that this further restriction is necessary owing to engineering difficulties and the order is needed because works are being executed on or near the road to carry out the dualling of the A30 between Chiverton Cross and Carland Cross including on and offline dualling of existing single carriageway with new grade separated junctions and under bridge construction.

While the Order is in operation traffic, including bicycle movement, along the highway specified in Schedule 1, will be temporarily restricted. No personnel, except upon the direction of a police constable in uniform, cause or permit any vehicle or pedal cycle to enter on, proceed or wait in the length of highway described above. Advanced Warning signs will be placed on site at least 14 days before the planned commencement of the works.
