HC Deb 12 February 1985 vol 73 c113W
Dr. Twinn

asked the Secretary of State for Transport if there have been any instances where lighting has been installed on a motorway to alleviate fog hazards; and if he will make a statement.

Mrs. Chalker

Yes. Fog was a consideration in providing lighting on the following motorways:

Junctions etc.
M1— Junction 3 to Junction 14 inclusive and Junction 24 to Junction 26 inclusive.
M5— Junction 15 to Junction 19 inclusive.
M6— Junction 10 to Junction 11 inclusive and Junction 20 to Junction 27 inclusive
M54—M6 Interchange to Junction 2.
M58— Junction 4 to Junction 6 inclusive.
M62— Junction 21 to Junction 24 inclusive.
M65— Junction 6 to Junction 10 inclusive.

We have instituted new studies to identify any stretches of the M25 and M42 motorways liable to fog.
