The bridge was opened in 1981 with a design life of 120 years. Geotechnical surveys prior to construction had indicated that the western approaches of the bridge would be liable to settlement and so they were built in early 1978 under a separate works contract and left to settle for 18–24 months before bridge construction started. Bridge construction took place from 1980 to 1982, during which time the eastern embankment was built, and the bridge was opened in 1981 but even…
