6 unusual facts about Navigable aqueduct


Greystanes, New South Wales

The Canal features the regionally well-known Canal bridge - also known as the Boothtown Aqueduct (as its original function was).

Navigable aqueduct

Early aqueducts such as the three on the Canal du Midi had stone or brick arches, the longest span being 18.3 metres on the Cesse Aqueduct, built in 1690.

Other cast iron aqueducts followed such as the single-span Stanley Ferry Aqueduct on the Calder and Hebble Navigation in 1839, with its innovative 50-metre through arch design.

Within ten years Telford had completed the far more ambitious Pontcysyllte Aqueduct on the Llangollen Canal over the River Dee valley—total length 307 metres.

In recent years the building of the Lichfield Canal Aqueduct prompted the UK government to pass legislation preventing a road being built in the path of a canal being renovated without providing a tunnel or aqueduct for it to pass.

The same canal, which includes a tunnelled section, crosses a second valley on the Chirk Aqueduct (1796–1801).


Tame Valley Canal

Between Tame Valley Junction and Rushall Junction it goes under the Midland Metro near Wednesbury and crosses over the former Grand Junction Railway (now part of the Chase Line) by aqueduct, near Tame Bridge Parkway railway station (an unusual case of the railway pre-dating a neighbouring canal).
