Michael Parsons obituary

Structural engineer who had a big hand in the creation of the Severn, Forth and Humber road bridges

Michael Parsons, who has died aged 92, played a key role in the design of Britain's three major suspension bridges, over the Forth, Severn and Humber estuaries - and was closely involved in the design of the first two suspension bridges over the Bosphorus in Turkey.

Working for the consultants Freeman Fox and Partners throughout his career, he was the originator of the streamlined box girder concept first adopted for the suspended deck of the Severn Bridge and taken up on most suspension bridges thereafter.
