How to build a bridge

To the makers of the infamous Squinty Bridge in Glasgow which is currently having to undergo major structural repairs after only being open for about 18 months.

Just have a look at the other bridges in Glasgow such as the South Portland Street Suspension Bridge, which I took a stroll over today and grabbed a few snaps of, which has been open since 1853 and at least lasted until 1870 before needing repairs after which it has been pretty much tickety boo ever since.
