During my army career we crossed many a Bailey Bridge, most of which had been given names by the sappers who built them. The one most remembered carried the sign "Twazzabuggatoo" that was built over a gorge. As the southern approach was on a cliff side road requiring an abrupt right-hand turn, it was obvious that the Engineers had built from the northern side - one can but imagine the effort that it must have been to manhandle the equipment down and up the other side. I know that the sappers of 8th Indian Division faced a similar problem when constructing a bridge over a river south of Ortona, Italy. This they named 'The Impossible Bridge." Anyone know of more extraordinary difficult to build Bailey Bridges?
