Bridges form a very big part in any electrification scheme. Not only do they have to be raised to provide clearance for the overhead wiring they also have to be modified to prevent members of the public from climbing on the parapet walls or coming into contact with any of the OHLE. A very distinctive style of arched bridge has become associated with electrification schemes. The shape of the arch can be created two ways. The first is to remove all the brickwork above the old arch and then use it as shuttering to cast a new concrete arch above the old one. When set the old brick arch is then removed and the bridge built back up above. The second way is to use precast concrete arch sections to rebuild the bridge after the original arch had been removed. To protect the public the bridge parapets are rebuilt higher with no foot holds to prevent climbing and the top of the wall is finished with angled coping stones. Footbridges are treated the same with regards to protecting the public as seen here at Kidsgrove. Things to note here are the extensions made to the original legs and the boarding up of the sides.

construction on the Piccadilly project.
Things to note are the high parapet walls and the difference in brickwork colour on the supporting walls. Many bridges were rebuilt with wider roadways with the footpaths supported by beams that cantilevered off the main structure as modelled here.
