The other great contrast is between the Second
Severn Bridge, and the First - seen on the right. The earlier bridge is
notable for possessing the clean lines of it's pioneering box girder construction,
specially designed to resist Severn Estuary wind gusts. On the other hand

surface can be a major and sometimes even frightening hazard for drivers,
necessitating closure in severe storm conditions while the Second Crossing
can remain open. |
