Bell Weir Lock

Bell Weir Lock is a lock on the River Thames in England by the right bank, Runnymede which is a water meadow associated with Egham of importance for the constitutional Magna Carta. It is upstream of the terrace of a hotel and the a bridge designed by Edwin Lutyens who designed an ornamental park gate house along the reach. The bridge has been widened and carries the M25 and A30 road across the river in a single span. The lock was first built by the Thames Navigation Commission in 1817; it has one weir which is upstream. The lock is the eighth lowest of forty-five on the river and is named after the founder of the forerunner of the adjoining hotel who took charge of the lock and weir on its construction.
