| Comment | The pavement and foundations on motorways are far thicker than on a normal road. Normal surface roads only have a pavement of about 2 inches on top of a foundation of 5 to 10 inches, while a motorway has a pavement of about 10 inches and a foundation of about 20 inches. The materials used are different as well. The pavement on a normal road is tarmac or asphalt while motorways have concrete pavements. They are built to entirely different standards.
Another factor is that motorways (and Trunk roads) are looked after and maintained by private firms awarded contracts by Transport Scotland while the normal city roads are looked after and maintained by Glasgow City Council. The issue there is obvious. |
