(a) to impose a temporary mandatory 50 mph speed restriction on both
carriageways of the M25 between Junction 9 and Junction 10;
(b) width restrictions in certain narrow lanes;
(c) overnight hard shoulder running; and
(d) overnight closure of the following:
(i) the clockwise carriageway of the M25 between Junction 9 and Junction 10 including the slip road leading to this carriageway at Junction 9 (A243/A245) at Leatherhead,
(ii) the anti-clockwise carriageway of the M25 between Junction 10 and Junction 9 (A243/A244) at Leatherhead, including the slip road leading to this carriageway at Junction 10 (A3 Portsmouth Road) at Wisley Interchange, and
(iii) both carriageways of the M25 between the ‘off’ and ‘on’ slip roads at Junction 10.
It is expected that the work would last for approximately 4 months starting
on or after Sunday 15th August 2010; the overnight – restrictions and
closures outlined at (c) and (d) above would be in operation between
2200 and 0530 hours on Monday – Thursday nights,
2300 and 0600 hours on Friday nights,
2200 and 0600 hours on Saturday nights and
2230 and 0530 hours on Sunday nights;
The closures at (d)(i) and (ii) above would take place for approximately 30
nights (15 nights for each carriageway) over that period.
During the closures outlined at (d) (i) and (ii) above, clockwise traffic would be diverted at Junction 9 (A243/A45) at Leatherhead, northwest on the A243 to the roundabout at its junction with the A244 and the M25 Junction 9 (anti-clockwise), northwest and north on the A244
(Oxshott Road/Leatherhead Road/High Street/Warren Lane/Copsem Lane) to Esher Common (A3) and southwest on the A3 to rejoin the clockwise carriageway of the M25 at Junction 10 at Wisley Interchange; anti-clockwise traffic would follow the same diversion route in the reverse
direction to rejoin the anti-clockwise carriageway of the M25 via the ‘on1 slip road at Junction 9 (A243/A244).
During the closures outlined at (d)(iii) above, traffic affected would be diverted via the ‘off’ slip roads at Junction 10 (A3 – Portsmouth Road) at Wisley Interchange and rejoin either the clockwise carriageway or the anti‑clockwise carriageway of the M25 via the ‘on’ slip roads at Junction 10 (A3) at Wisley Interchange.
