The bridge is constructed as "two segmental arches on a slightly skewed plan".
The start of the ladder is via a segmental arch built with granite blocks.
It is accessed from the tower through a segmental arch with a single chamfered order.
In the 1960s, the area around the doorway's segmental arch was covered with a layer of plaster.
The windows in the ground floor have segmental arches.
The bridge is built of stone, has three segmental arches, and was completed in 1856.
On each side of the porch are three-light windows under a segmental arch.
The street and buildings sit above three segmental arches of equal span.
Most of them, except for those under the original first floor porches and in the kitchen building, feature round or segmental arches.
The principal entrance, a segmental arch, is reached by a stone bridge of three spans.
