There is much to be learned from the Erskine Bridge. Was it a mistake to build it as one first part of a ring road round Glasgow that was then never completed? Was the bridge ever strong enough with strengthening works starting a few weeks after opening? Should tolls ever have been used on the bridge and if so should they have been removed?
The intriguing thing about the Erskine Bridge is that a bit like many complex transport policy choices the key issues have been ducked for 50 years. It is unlikely that they will be ducked for the next 50 years so this fascinating review by Bill Heaney in the Dumbarton Democrat frames them as they are currently perceived locally.
