Lea Road Bridge (TJC1 26)

Lea Road Bridge, built in 1870 for the Midland Railway to designs by J.S. Crossley, is a stone overbridge spanning the River Drone and providing access near the northern end of Dronfield Station. The bridge is constructed from snecked, quarry-faced Derbyshire gritstone walling with tooled ashlar dressings and red brick soffit linings.

The bridge has an L-shaped plan. It consists of two segmental arches spanning the railway line and a cutting, a ramped approach road at a right angle on the east side, and three further segmental arches, one of which spans the River Drone. The main section features a span over the railway and a smaller, approach arch over the west embankment, both sharing detailing characteristic of bridges along this section of the line. This detailing includes V-jointed, punch-dressed stepped voussoirs and drafted margins; the voussoirs return as elongated ashlar quoining to the brick soffit linings. The arches spring from pick-faced impost blocks and integral impost bands with tooled margins and chamfered upper arrises. A continuous string course runs across the bridge face above the arches. The parapet follows the road alignment and is curved, matching the string course. It has steeply-curved, pick-dressed copings with drafted margins and hipped ends. All other stonework, including the abutments and spandrels, is snecked and quarry-faced.

The bridge faces terminate at raking piers with shallow, hipped copings set beneath the parapet coping. Walls of squared masonry flank the approach road, abutting these piers with a straight joint on the west side. On the east side, the bridge extends beyond the piers and turns sharply north to form a ramped approach to Chesterfield Road. Within the curved section of the flanking wall is a segmental arch spanning the River Drone. The approach road is divided by four piers, with two segmental arches between the middle two. The final section has a lower parapet, possibly altered, with modern steel railings. An opening in the south parapet, at the top of the approach road wall, provides access to a 20th-century timber footbridge leading to Dronfield Station. The 20th-century timber footbridge leading to Dronfield Station is not considered to be of special architectural or historic interest.
