==Construction and repairs==
Construction of the viaduct began in 1859; the Chief Engineer and Resident Engineer being [[FileJohn Fowler]] and [[Henry Orlando Bridgeman | Henry Bridgeman]] who were also responsible for [[Victoria Bridge]]. Although the most of Bewdley station itself is cut into the sandstone rock and stands firmly on it, the viaducts at each end of the station are off the rock and stand on softer alluvial deposits. Wet weather in December 1860 impeded construction, causing a supporting wall to the embankment to collapse.<ref>[https: Wribbenhall_Viaduct_plaque_20170831//www.jpg|thumb|300px|right| Small repair with date plaque]britishnewspaperarchive.co.uk/viewer/bl/0000401/18601228/030/0005 Shrewsbury Chronicle - Friday 28 December 1860]</ref>
The viaduct was built from 1859; the Chief Engineer and Resident Engineer being [[John Fowler]] and [[Henry Orlando Bridgeman | Henry Bridgeman]] who were also responsible for [[Victoria Bridge]]. The viaduct is 112 yards in length, with seven brick arches of 25ft span and a larger skew arch of 48ft 9in span over the Kidderminster Road.<ref name=Marshall94>[[Bibliography#Books|Marshall (1989)]] p. 94.</ref> Wet weather in December 1860 impeded constructionAt the north end, causing the embankment is supported by a supporting sloping retaining wing wall to the embankment to collapse.<ref>[https://www.britishnewspaperarchive.coor 'revetment' which extends for a further 65 yards.uk/viewer/bl/0000401/18601228/030/0005 Shrewsbury Chronicle - Friday 28 December 1860]</ref>
The viaduct was originally built using a combination of red brick and locally quarried local red sandstone. The latter sandstone came from a quarry at the top of what is now Maypole Close, just a few yards north of the viaduct. Although it appeared strong and hard when freshly cut, it was prone liable to weatheringsoften, split and disintegrate when exposed to the atmosphere. This was probably known by the contractors at the time with its use being a cost saving measure; the stone and in 1915 large sections were cut out brickwork on [[Dowles Bridge]] and other structures on the [[Wyre Forest Line|Tenbury and replaced Bewdley Railway]] built only about two years later by blue engineering bricks, as can be seen on the main photographsame contractors is of a far better quality.<ref name=SVR106>SVR News 106, “Bewdley Viaduct” "Bewdley Viaduct" (John Marshall)</ref> The neighbouring [[Accommodation bridge off Northwood Lane]] underwent similar repairs at that time which included a date plaque set into <ref>SVR News 113, "Silica, Sandstone and the bricks.

The viaduct was acquired by the SVR in preservation at the end of 1972 as part of the southern section of the line between Alveley Colliery and Foley Park. In the early 1990s a survey was carried out. Since the time of the GWR repairs there had been further deterioration and much of the stonework was crumbling. Drains had become blocked and water had been seeping through the sandstone and soffits of the arches for many years, causing the mortar to deteriorate. The winter of 1992/93 saw a major refurbishment by the SVR including installing a waterproof membrane and relaying of the track bed. The external contractors were William Jackson (Langley Green) Limited, who had previously been involved with the [[The development of Kidderminster Town Station|construction of Kidderminster Town Station in 1984-5]]. The work was combined with the rebuilding of the north end of Bewdley platform 1 which was in danger of collapsing down the embankment. Work began at the beginning of January 1993 and favourable weather enabled it to be completed on schedule in time for the season opening on
13 March.<ref name=SVR106/>
 
The viaduct has seen further major refurbishments since. In February 2018 work started on the long wing wall by contractors (Walsh Construction Ltd), using the same Cumbrian sandstone from St Bees quarry that the SVR have used elsewhere on the viaduct.<ref>[https://www.svrlive.com/winter-works-2018 SVRLive, 'Winter Works 2018', 21 March 2018]</ref>

==Listing==
The viaduct and its revetments are a Grade II listed building, Historic England List Entry Number 1386197. They were first listed on 5 November 1998. The listing provides a more technical description of the structure as follows:
 
:''Railway viaduct. 1859-60; by Sir John Fowler and Henry Bridgeman, for the Severn Valley Railway Company. New red sandstone '''ashlar''' with brick arches and repairs. Eight bays. The principal bay at the NW end has a segmental skew arch with rusticated sandstone '''voussoirs''', '''imposts''' and is flanked by '''pilasters'''. The other seven arches to the SE have brick round arch rings, the piers with sandstone '''imposts'''. Sandstone parapets with string and terminal piers. At the NW end the embankment is supported by a '''revetment''' extending for about 60 metres. Some later '''buttresses'''.''
 
The terms used in the listing are:
*Ashlar: masonry made of large square-cut stones, used as a facing on walls of brick or stone rubble.
*Voussoir: a wedge-shaped or tapered stone used to construct an arch.
*Impost: the top course of a pillar that supports an arch.
*Pilaster: a rectangular column, especially one projecting from a wall.
*Revetment: a retaining wall or facing of masonry or other material, supporting or protecting a rampart, wall, etc.
*Buttress: a structure of stone or brick built against a wall to strengthen or support it.

==Former footbridge north of Wribbenhall Viaduct==
North of [[File: Summer_Hill_Footbridge.jpg|thumb|300px|right|Summer Hill footbridge in the early 1900s]]Proceeding north from Wribbenhall Viaduct, the [[Tenbury Branch | Tenbury and Bewdley Railway]] and Severn Valley Railway ran parallel for around a mile on the left and right hand lines respectively. On 15 March 1892 the GWR Engineering Committee authorised construction of a plated girder passenger footbridge a short way over the two lines around 150 yards north of the Viaduct, connecting Northwood Lane and Summer Hill. This was later demolished in the 1930s, although the brick footing on the Summer Hill side of the line is still visible next to the track bed.<ref name=Marshall94/> . <br clear="all"/>
