In the current dry weather it’s quite easy to climb down and inspect the underside of the arches of Matlock bridge, a structure thought to date from the fifteenth century. As can be seen in the photo, this reveals a clear joint between the original structure and the widening carried out in 1904, which allowed two-way traffic on the bridge (since reduced to one-way in the latest traffic scheme). This is a reminder that most pre-twentieth century bridges would have only been wide enough for one cart or coach at a time, as is still the case with One-Arch Bridge at Chatsworth.

Some were still narrower, such as Holme Bridge, on the River Wye upstream of Bakewell; just wide enough for a train of packhorses to cross. This is a reminder that bridge building was high skilled and thus expensive, yet bridges were absolutely critical to the transport network. The earliest bridges probably had a wooden superstructure resting on stone piers: easier to construct but liable to be washed away in any flood. All-stone bridges, with arches and breakwaters to deflect floating debris, were commonly constructed from the twelfth century but their cost was often met by a local monastery or abbey. In addition, tolls were frequently charged to pay for their upkeep.

Important river crossing often had chapels attached, as with St Mary’s bridge in Derby (the only bridge in medieval times) or Cromford bridge (now ruined). The chapels would have provided a shrine for travellers to pray for a safe onward journey, and doubtless to leave an offering for bridge maintenance.

With most ancient bridges, establishing a date is almost as difficult as dating a road. The example above, with its simple round arch, and too narrow for a cart, could be anything from a hundred and fifty to a thousand years old, and would probably have been repaired many times after especially violent floods.
