Happy 30th Birthday to the Second Severn Crossing, which was formally opened on 5 June 1996! The original Severn Bridge had been in use since 1966 but it was clear that a new, more aerodynamic, bridge was required to deal with the huge increase in traffic and cope better with inclement weather - especially high winds - strong currents, and the second highest tide in the world (14.5 m/ 48 ft)! Construction on the second bridge started in April 1992 and innovative construction methods (including 2,302 precast segments) and 3 m high ‘baffle plates’ (to reduce closures during high winds) were used. The total length of the bridge is 3.2 miles: the 2 access viaducts (English end 2,103 m long and Welsh end 2,077 m) were constructed from their own sides and joined to the central cable stayed “Shoots bridge” over the deep channel in the centre. The pylons are 149m above the river bed and the cables vary in length from 35 to 243m. The total cost was £330 million. In 2018 the bridge came into public ownership and was renamed the Prince of Wales Bridge, also, more popularly, the collection of tolls ceased in December 2018.
