CRL were employed by Derbyshire County Council to carry out the repairs to a historic road bridge in Belper, Derbyshire. Belper Bridge, which is a Grade II listed structure, carries the A517 over the River Derwent and is situated just below a series of weirs, retaining walls and sluices. It is a triple arched ashlar bridge, was built by Benjamin Marshall and dates back to 1796.
The works included re-painting the parapets, barrier guard rails and cantilevered foot way support beams, waterproofing of the foot ways, minor concrete repairs, re-pointing the masonry and carriage resurfacing. Works on the underside of the bridge could only be done at one arch at a time to allow the river to still flow freely.
The works started in mid-June with the first phase involving the installation of pontoons to the first arch. Once this was completed a scaffold access staircase was erected on the pontoon which was designed to move up and down with the rise and fall of the river. Works to the top side of the bridge were carried out using a traffic management system to form a road closure. The project was completed in nine weeks, one week ahead of programme.
