[1][2][3] From the late 18th century cast iron framed bridges may have had an unreinforced cast concrete deck, or had their structure encased in concrete, for example the Homersfield Bridge, constructed between 1869 and 1870, between the English counties of Suffolk and Norfolk.

All barrel sections were reinforced similarly, regardless of the forces acting on it.
