A masonry skew arch bridge photographed shortly after its completion in 1898, showing the helicoidal nature of its stonework. Sickergill Skew Bridge over the River Raven at Renwick, near Penrith. A skew arch (also known as an oblique arch) is a method of construction that enables an arch bridge to span an obstacle at some angle other than a ...
Hereford Road Skew Bridge is a disused railway bridge in Ledbury, Herefordshire.Built in 1881 to carry the Ledbury and Gloucester Railway across the Hereford Road at an angle of approximately 45°, it was built as a ribbed skew arch with stone spandrels and wing walls, and ribs of blue brick.
The bridge has an unusually great skew angle of 63°, [note 2] requiring a large skew span of 42 feet (13 m) for a bridge with a relatively small clear span of only 18 feet (5.5 m). [10] As the bridge is in open countryside and the line is curved near this point, it is unclear why such a difficult and expensive bridge was chosen, rather than ...
Southdown Road Skew Bridge looking along the barrel. Note the substantial retaining wall to the left of the arch. The easiest way to visualise Boucher's concept for the ribbed skew arch is to consider a regular arch bridge that carries the railway at right angles across the road and then to slice it vertically at regular intervals along the axis of its barrel, the planes all being parallel ...
The bridge consists of three skew arches, each with a span of 30 feet (9 metres), standing on two rusticated pillars. It carries the railway 60 feet (18 metres) over the River Gelt in a deep but narrow gorge. The bridge has a skew angle of 27 degrees. It is built from rusticated red sandstone, with smoothed voussoirs and V-shaped joints.
The Skew Arch Bridge in Reading, Pennsylvania, also known as the Askew Bridge and nicknamed the Soap and Whiskey Bridge, is an historic skew arch bridge that was completed in 1857. Its design enabled it to carry two tracks of the Philadelphia and Reading Railroad (P&R) at an angle over Sixth Street in Reading, Berks County, Pennsylvania. [3]
Because it crosses the river at an oblique angle, it was constructed as a ribbed skew arch bridge, with each span composed of a series of offset stone arches. While not as strong as skewed barrel vault spans, these spans were much easier to build, while still assuring that the bridge's abutments were parallel to the water flow.
The skew arch (also known as an oblique arch) is used when the arch needs to form an oblique angle in the horizontal plane with respect to the (parallel) springings, [96] [97] for example, when a bridge crosses the river at an angle different than 90°.
