The Drypool bridge over the River Hull is a Scherzer lifting bridge and was designed by W. Morris, the Hull City Engineer. It was fabricated in Hull, being completed in March 1961.

The Duke Street Scherzer Rolling Bascule Bridge at Birkenhead spans the channel between East Float and West Float. It replaced a swing bridge in the 1930s.

Keadby Bridge, more formally known as the King George V Bridge, crosses the River Trent near Althorpe and Keadby in Lincolnshire, England. It was designed by Alfred Charles Gardner FRSE MIME. This Scherzer rolling lift bridge carries both road and rail traffic across the River Trent. It was built between 1912 and 1916 by the Great Central Railway to replace a previous swing bridge built by the South Yorkshire Railway and opened in 1864. It carries a double track railway line on the southern side, and the two-lane, single carriageway A18 road on the north side. Its 50-metre (163 ft) electrically powered bascule (lifting span) was one of the first of its type in Britain and, when built, was the largest in Europe. Designed by James Ball and C A Rowlandson and built by contractors Sir William Arrol & Co., it has three main spans and two approach spans. The eastern main span was the one that lifted. The Scherzer bascule rolled and rotated on counterbalance. It was electrically powered, originally by a large storage battery fed by petrol-driven generators housed in the engine room beneath the east approach span. This was later modified to mains electricity. The bridge has not been lifted since 1956. The bridge was widened and the headroom increased in 1960 and the bascule was fixed in position. At the same time, the signal cabin was removed from the bridge structure. The tracks on the railway were fixed in place.

These Scherzer rolling bridges carry the MBTA Commuter Rail over the Charles River in Boston. Originally this was the site of a bascule drawbridge for the Boston and Lowell Railroad, built 1835. It was the first movable railroad bridge in the United States. In 1931 the Charles River bridges were replaced after extensive filling and dredging meant that the channel of the Charles River was relocated further away from North Station to allow the terminal tracks to converge into eight main leads crossing the river. The four new structures were double-track, single-leaf rolling bascule bridges. All four were nearly identical in design, varying only in their length and the degree of their skew, two spans crossing the channel at a slightly greater skew than the others. Two were 87 feet in length and two, 97 feet. Each span carried a single 629-ton overhead concrete counterweight and, operated by two electric motors, was controlled from the second floor of the new signal and interlocking station, located nearby on the north side of the river. The bridges were designed by Keller & Harrington, Chicago, while the steelwork was fabricated and erected by the Phoenix Bridge Company, Phoenixville, Pennsylvania. Today, only these two spans remain.

The double-leaf Scherzer Rolling Lift Bridge over the tidal Dee at Queensferry was opened in 1926 to replace the 1897 Victoria Jubilee Bridge which incorporated a retractable timber structure. The new bridge was designed by Mott Hay and Anderson, and built by Sir William Arrol and Co. Ltd, for £83,051. The lifting spans, totalling 134ft are now fixed in place and the barges carrying Airbus wings have to arrive at a low enough state of the tide to allow headroom for them to pass.
