The New Ashton Arch Bridge [was] constructed in the town of Ashton, Western Cape, on Trunk Road 31 Sections 2 (start of “Route 62”, an important tourist destination and national road) crossing the Cogmanskloof River. The bridge replaces an existing multi-arch bridge, built in the 1930's, which did not fulfil its functional requirements, inter alia service life, width and hydraulic capacity, anymore.

The new tied-arch bridge comprises a cable-supported concrete deck which spans 110 metres between supports with arching ribs rising 22 metres above the asphalt road surface.

The superstructure, which was completed mid 2020 adjacent to the existing road-alignment, will be launched transversely into its final position onto the adjacent recently completed substructure during August 2021, a first of this kind of construction in Africa.

The bridge was successfully moved into place on the 14th and 15th August 2021. The process can be viewed on YouTube.
