Wakefield’s mediaeval bridge and chantry chapel. The nine-arched bridge, over the River Calder, was built between 1342 and 1356, when the chapel was also consecrated. The new bridge was built alongside in 1929-30.
Marsden’s Eastergate packhorse bridge, on an old route to Rochdale. The original bridge would not have had walls, or the horses’ packs would not have got through.
Aldwark toll-bridge: one of a small number of old toll-bridges surviving in the UK. It is the only crossing of the River Ure between York and Boroughbridge, connecting the villages of Aldwark (in the old North Riding) and Great and Little Ouseburn (in the old West Riding). It was built in 1772 by John Thomson, who had formerly ferried people across in a rowing-boat: he obtained a private Act of Parliament to build the bridge. It’s quite scary crossing it, but well worth the 40p it now costs – though the toll-collector is said to go home at 7.30 pm.
North Bridge, Halifax: a magnificent cast-iron Victorian gothic structure built in 1869 over the rather insubstantial Hebble Brook (and the railway).
Middlesbrough’s Transporter Bridge, completed in 1911.
Scammonden Bridge: photo taken in 1970, when the M62 in a huge cutting below was still under construction.
