D902 (Hautes-Alpes)

D902 (Hautes-Alpes) is a major departmental road in the French Alps, forming a critical high-altitude traverse between the Queyras and Briançonnais regions. It is internationally renowned for its inclusion in the Tour de France, crossing two legendary mountain passes, the Col de Vars and the Col d'Izoard. The route offers dramatic landscapes through the Écrins National Park and serves as a vital transport link for the communes of the Hautes-Alpes.

Route description

The D902 begins in the historic town of Guillestre, situated in the Durance valley, and immediately begins its ascent. The western climb tackles the southern slopes of the Massif des Écrins, winding through the commune of Vars towards the Col de Vars, a pass at an elevation of 2,109 meters. After descending into the Ubaye valley near Saint-Paul-sur-Ubaye, the road turns northeast to commence the formidable climb to the Col d'Izoard. This eastern ascent traverses the iconic Casse Déserte, a stark, rocky landscape within the Communauté de communes du Briançonnais, before reaching the pass at 2,360 meters. The final descent follows the Gorges de la Cerveyrette into the fortified city of Briançon, a UNESCO World Heritage Site and the route's terminus.

History

The road's origins lie in strategic military improvements during the late 19th century, overseen by the French Third Republic to secure the border with the Kingdom of Italy. Its two high passes have been pivotal sites in the history of the Tour de France, with the Col d'Izoard first featured in 1922 and both climbs becoming regular, decisive battlegrounds. Legendary cyclists like Fausto Coppi, Louison Bobet, and Marco Pantani have forged their reputations on its slopes. The route's infrastructure has been modernized over decades, but it retains its challenging character, also featuring in other races such as the Critérium du Dauphiné and the Paris–Nice event.

Major junctions

The D902 intersects with several other significant routes in the Alpes-de-Haute-Provence and Hautes-Alpes departments. At Guillestre, it meets the N94 from Gap and the Durance valley. Near the summit of the Col de Vars, it connects with the D900 road descending to Barcelonnette in the Ubaye valley. On the approach to the Col d'Izoard, a junction with the D947 provides access to Château-Ville-Vieille and the heart of the Queyras. Its eastern terminus in Briançon is a major hub, intersecting with the N91 towards Grenoble, the D1091 towards the Col du Montgenèvre and Italy, and the Route des Grandes Alpes.
