Tardebigge

Lock 33 on the Worcester and Birmingham Canal. This is the 5th lock from the bottom of the 30 locks on the Tardebigge lock flight.
Of particular interest here is the lock tail bridge, cantilevered out from the off-side, which was to allow horse-drawn boats to be pulled into or out of the lock without the need to disconnect the towline.

Birmingham

Worcester Bar at Gas Street, Birmingham. This narrow gap is where the Worcester and Birmingham Canal meets the Birmingham Canal Navigations. Ahead, the canal passes below Broad Street.
Originally there was a 7 foot wide barrier between the two canals, over which cargo had to be manhandled, until the stop-lock channel (pictured) was built, with toll houses for each canal company. The footbridge is in fact modern, built in the traditional BCN style.
