How many miles from London to Sussex?
That depends on where in Sussex. London-Brighton is about 51 miles.
If you are refering to Crawley, Sussex, you are way off. Although it is not a part of London, it was built for a settlement to ease congestion in London, I believe. It is many miles North of Brighton, South of Horley in Surrey, North-east of Horsham. It is also just south of London Gatwick Airport, on the Surrey-West Sussex Border but on the Sussex Side. I hope my answer has helped you slightly. Good…
50 miles taking this route: Follow M23 & A23 to The SOUTH, from London, to A27 to LEWES and NEWHAVEN (to THE UNIVERSITIES). Follow signs to A27 towards LEWES and NEWHAVEN. Take A27 to B2123 to ROTTINGDEAN and FALMOUTH (to UNIVERSITY of SUSSEX), which is the SECOND JUNCTION that you will approach on A27. EXIT, and then turn left into the campus.
