A road is a thoroughfare for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, whose primary function is to serve as public spaces, the main function of roads is transportation.
The Millau Viaduct (French: le Viaduc de Millau) is a large cable-stayedroad-bridge that spans the valley of the River Tarn near Millau in southern France. Designed by the structural engineer Michel Virlogeux and British architect Norman Foster, it is the tallest vehicular bridge in the world, with one mast's summit at 343 metres (1,125 ft) — slightly taller than the Eiffel Tower and only 38 m (125 ft) shorter than the Empire State Building. The viaduct is part of the A75-A71 autoroute axis from Paris to Béziers. It was formally dedicated on 14 December 2004, inaugurated the day after and opened to traffic two days later. The bridge won the 2006 IABSE Outstanding Structure Award.
The bridge’s construction broke three world records:
The highest pylons in the world: pylons P2 and P3, 244.96 metres (803 ft 8 in) and 221.05 metres (725 ft 3 in) in height respectively.
The highest mast in the world: the mast atop pylon P2 peaks at 343 metres (1,125 ft).
The highest road bridge deck in the world, 270 m (890 ft) above the Tarn River at its highest point.

Image 32Car fatalities per pax-km vs. car usage per pax-day; in Europe. It seems, at least in these European countries, that car fatalities per person-km have no strong correlation with massification of car usage. The average car usage in these countries is around 30km per person-day with varying number of fatalities ratios. These differences might be related with different cultural approaches to traffic codes, or more safety measures implemented on such countries. (from Road traffic safety)
