 The large, bow-shaped Teddington Weir is against the opposite bank.A series of two footbridges at differing heights make up a structure which crosses the locks, the middle island that has the lock keeper's cabin and the weir pool, Teddington Lock Footbridge.The Navigation Act obtained in April 1771 by the Thames Navigation Commission did not allow them to build locks below Maidenhead Bridge, but from 1802, several plans for locks in the First District of the Thames, stretching from Staines to Teddington, were drawn up.
