At the south portal of the tunnel, at the edge of the road, there is a monument to Henri Desgrange, instigator and first director of the Tour de France. The memorial was inaugurated when the tour passed on 19 July 1949. Whenever the tour crosses the Col du Galibier, a wreath is laid on the memorial. The Souvenir Henri Desgrange is awarded to the first rider across the summit of the highest mountain in each year's tour. In 2006, the prize of 5,000 euros was claimed on the Col du Galibier by Michael Rasmussen.
