Grosvenor Bridge

Grosvenor Bridge is a road bridge over the River Dee in Chester, designed in 1824 by Thomas Harrison and constructed between 1827 and 1833 under the supervision of his pupil William Cole the younger, with Jesse Hartley as a consultant and James Trubshaw as the contractor. The construction cost was £50,000. The bridge is made of red and cream Peckforton sandstone ashlar and features a single deep segmental arch spanning 200 feet across the river, which was believed to be the longest stone arch in the world at the time of its completion.

The bridge has pavilion-abutments and archways for pedestrians and coaches on each side. The outer abutments are quadrant-shaped, stepping down with the slope of the embankments. The river arch consists of two rings of cream voussoirs with red sandstone outer moulding and two rings of long shallow voussoirs above, along with recessed spandrel panels, a frieze, and a cornice adorned with rectangular modillions. The parapet is made of round-topped ashlar slabs, with a raised panel above the crown of the arch.

The battered Doric pavilions have rusticated plinths of tooled ashlar and a curved batter on their faces, with a two-course frieze above the plinth, a round-arched niche, a stone panel, and a Doric architrave, frieze, and pediment. The round-arched side openings and the outer abutments are constructed from rock-faced masonry. A slate plaque on the bridge provides historic details.
