The Madingley Road site is situated to the west of Cambridge. The best way of getting to this site is to turn off the M11 at junction 13 whilst heading northbound. From there take the turning towards Cambridge on the A1303. After a short distance you will find the Madingley Road Park & Ride site on your left. Please note that junction 13 cannot be directly reached from the M11 heading south.
If you are southbound on the M11 and want to use Madingley Road: proceed to junction 12 where you can leave the M11 and come back on yourself (heading north again) and exit at junction 13. Alternatively you can continue southbound down the M11, exit at junction 11 and use the Trumpington site.
