More than seven million bricks and 12,338 cubic metres of stone were used in its construction. Some 3,000m of timber were used for the arch centring, temporary platforms and the permanent foundation piles. During construction, on October 6, 1849, two of the 41 arches then completed collapsed, with the loss of three lives.

The southern side of the bridge, nearest the remains of the Abbey, bears the only decorative treatment.
