There has been a river crossing point since 1329 in the centre of the village, at the site of the current 'County Bridge'. A bridge is recorded in this location under the name "Elphaborough Bridge", after the name of Elphaborough Hall on the further side of Cragg Brook. Records of a grant issued to the local township for the purchase of timber stated it was for "repairs to Mitholmroide Bridge", in 1638. Similar records show that the current stone bridge was erected in 1684 by Timothy Wadsworth, at a cost of £50. The current bridge was constructed in two parts (and now consists of four extensions). The original packhorse style bridge in 1638, and on the upstream side, the bridge was widened and two extra arches on the south end were added to ease the gradient, although the two new arches were considerably smaller, the bridge now consists of four arches in total. In the 19th century, with shops being constructed on the north end riverbank, and a new premises being built for the Mytholmroyd Co-Operative Society right up to the water's edge on the south bank, two of the bridge's arches are mostly hidden. However, the premises were built with a large opening underneath the buildings, allowing floodwater to still pass through the two hidden arches underground. Mytholmroyd Bridge was eventually taken over by West Riding County Council, which gives the historic bridge its present name of "County Bridge".
