| Aquaducts (a.k.a. aqueducts) allow
canals to cross over obstacles such as rivers, highways, railroads,
and even other canals! The Chirk and the Pontcysyllte, two
aqueducts on the Llangollen Canal are quite impressive!
The Chirk Aquaduct was built in 1801 and spans the Cerrog
Valley. A railroad viaduct stands impressively along side and
slightly higher. Immediately after crossing the Chirk Aquaduct
going upstream, you met the Chirk tunnel of 459 yards in length.

South of the Welsh town of Trevor lies
the grand Pontcysyllte aquaduct that was opened for used in
1805. This aquaduct spans across the river Dee with a length
of over 1,000 feet and a height of 127 feet. The aquaduct
consists of an iron trough and is supported by massive stone
piers. The east side of the aquaduct has a towpath with
protective high railing, however, the west side has a unprotected
sheer drop!
