TUESDAY'S blockage on the A80 should be a lesson to us and a warning to all who want to upgrade this very road to a motorway. We could look forward to this sort of congestion daily for four years!

The Forth Valley and points north need proper links with the west of Scotland. It is time a decision is made to convert a strip of Kelvin wastelands to complete the central motorway system.
