The design was chosen because the river banks are very low at the desired crossing point where an ordinary bridge would need a very long approach ramp to attain sufficient height to allow ships to pass under, and a ferry could not be used during low tide at the site.
Principal dimensions
A Corporation of Newport drawing dated December 1902 is calibrated in metres. The height of the towers is, and the height to the underside of the main girder truss above the road level is. The span between the centres of the towers is, and the clearance between the towers is quoted as being ; however, including the cantilevered sections, the main girder truss gives the bridge an overall length of. The distance between the centres of the anchorage caissons is. Power to propel the transporter platform or gondola is provided by two electric motors, which in turn drive a large winch, situated in an elevated winding house at the eastern end of the bridge. This winch is sufficient to drive the gondola through its total travel at a speed of. This is the oldest and largest of the three historic transporter bridges which remain in Britain, and also the largest of eight such bridges which remain worldwide). When compared with Middlesbrough's Transporter Bridge, the Newport Transporter is taller, but less in overall length. It also utilizes approximately of steel compared to used to construct Middlesbrough's Transporter. This difference in weight is mainly due to the Newport bridge making use of cables to support and induce tension into its structure to a far greater extent than the Middlesbrough bridge.
Other information
Today, the bridge is considered an “iconic symbol” of the city of Newport, particularly as a mark of its industrial heritage. As well as a working transport link, the bridge is also open as a tourist attraction – visitors can climb the towers and walk across the upper deck for a small charge. The bridge forms part of the classified highway network and is also where route 4 of the National Cycle Network crosses the River Usk and route 47 begins. It was the focal point of the localmillennium celebrations of 2000, where fireworks were fired from its length, and has been featured in several movies and television shows. It was the centre-piece of the Crow Point Festival in September 2006 to celebrate its centenary. It is used for charity events such as sponsored abseils.
Refurbishment
The bridge was shut down in 1985 because of wear and tear. Following a £3 million refurbishment, it reopened in 1995. Service was suspended again in December 2008 with the bridge facing a £2 million repair bill. £1.225 million was spent on refurbishment, financed by grants from the Welsh Government, Newport City Council and Cadw. It re-opened on 30 July 2010. The bridge was closed on 16 February 2011, because of operational problems, but re-opened again on 4 June.
The transporter bridge provided the setting for some scenes in the 1959 British crime drama filmTiger Bay, which was set in Cardiff and therefore gave audiences the impression that the bridge was in Cardiff and not Newport. The bridge also appears in an early scene in the 1972 experimental film The Other Side of the Underneath by Jane Arden and features extensively in the 1996 video for the song "Talk to Me" by Newport band 60 Ft. Dolls.
Visitor centre
The Visitor Centre is located on the west bank and features exhibits on the history of the bridge, its construction and other transporter bridges around the world. The centre has a painting of David Pearce, the former undefeated Welsh and British Heavyweight Boxing Champion 1983–1985. Pearce used to run up the steps of the Transporter Bridge during his training. The centre is open at weekends.
