Directions by road
The Harwell Campus is situated on the A4185 approximately halfway between Newbury and Oxford and can be accessed from the Milton interchange of the A34. If you see a large doughnut shaped building that looks a bit like a flying saucer you are very near our offices; that is the Diamond synchrotron source.
- From the A34 (Southbound) - Exit the A34 at the Milton Interchange Junction, the A4130 (A417) exit signposted Milton, Chilton, Didcot and Wantage. At the roundabout take the fourth exit signposted A4130 Wantage, Steventon, Drayton, Harwell. Follow this road for one and a half miles and continue straight on at the Rowstock roundabout onto the A4185. After about two miles turn right at the roundabout onto Fermi Avenue (signposted Harwell Business Centre, RAL, NRPB). Go straight across two mini roundabouts and Cobalt can be found on the right hand side in the Electron building (green sign). If you come to the main RAL entrance on the left you have gone too far.
- From the A34 (Northbound) - Exit the A34 at Chilton Junction, branch left (signposted, Wantage), then merge onto the A4185. At the next roundabout take the 1st exit (signposted Harwell Business Centre, RAL, NRPB). Go straight across two mini roundabouts and Cobalt can be found on the right hand side in the Electron building (green sign). If you come to the main RAL entrance on the left you have gone too far.
- From Heathrow Airport - Take the M4 motorway towards Slough, Reading and the West. Continue as far as junction 13 and then head North for about 8 miles on the A34 towards Oxford and follow the A34 directions given above.
- From Gatwick Airport - Take the M23 to London and Guildford. At junction 7/8 join the M25 to Heathrow and Watford.
