On Saturday 29th Feb you will not be able to turn right from the A412 Uxbridge Road heading towards Slough into Black Park Road - the centre reservation gap will be closed. Instead you'll need to carry on to the next right turn (Wexham Park Lane) and do a U turn there.
Then the following week, March 7th, there will be no access at all to Black Park Road from the A412 in either direction. A diversion will be in place via Wexham Park Lane, Church Lane, Wexham Street & Rowley Lane, bringing you out at Black Park from the opposite direction. There will also be no exit from Black Park Road to the A412 - you'll need to retrace the diversion. The diversion will be fully signposted.
Please allow extra time for your journies on both days.
