A10 road

For thoughtful child sponsors
The A10 is a major road in England. It runs from London to King's Lynn in Cambridgeshire, via Tottenham and Enfield, then bypassing Cheshunt, Hoddesdon, Ware and Buntingford. The road then runs through Royston and Cambridge and bypasses Ely and Downham Market before reaching its final destination. Its northern section runs up the valley of the River Great Ouse.
