Tour Scotland video of a drive East on the M8 Motorway on ancestry visit to Glasgow. The M8, Glasgow section, is unusual amongst UK motorways, and more similar to many USA Interstates, in that it directly serves, and bisects, a large urban area, whereas most other motorways bypass such conurbations. The central Glasgow section is elevated above much of the surrounding area on a concrete viaduct, including several incomplete constructions such as several pedestrian overpasses and adjoining arterial roads.
