The canal which this mighty bridge carries across the gulf is about nine feet wide, and occupies about two-thirds of the width of the bridge and the entire western side.
The footway is towards the east.

From about the middle of the bridge there is a fine view of the forges on the Cefn Bach and also of a huge hill near it called the Cefn Mawr.

We reached the termination, and presently crossing the canal by a little wooden bridge we came to a village.

My guide then said, "If you please, sir, we will return by the old bridge, which leads across the Dee in the bottom of the vale." He then led me by a romantic road to a bridge on the west of the aqueduct, and far below.

It seemed very ancient.
