Norwegian National Road 7 (Norwegian: Riksvei 7, Rv7) is a national road in Norway which runs from the town of Hønefoss in Buskerud county to the village of Granvin in Vestland county. The route is 387.6 kilometres (240.8 mi) long and runs east–west through Viken and Vestland counties over the vast Hardangervidda plateau.
The road begins at the European route E16 highway just south of Heradsbygda in Ringerike municipality and runs through the Sogna river valley to the village of Sokna (this part is called the Soknedalsveien). It then continues further on to Hamremoen and up along the east side of the lake Krøderen to Gulsvik, where it crosses the river and then follows the Hallingdalen valley through Flå, Nesbyen, Gol, Torpo, Ål, Hol, and Geilo (this part is called the Hallingdalsveien). From there, the road begins its path across the Hardangervidda plateau via Ustaoset and Haugastøl, passing the Vøringsfossen waterfall while descending through 4 tunnels (including the 1,893-meter Måbø Tunnel) into the Måbødalen valley in Eidfjord. The road follows the Eid Fjord for a way before crossing the fjord via the Hardanger Bridge (opened in 2013, there was a ferry here prior to that time). The road continues through the Vallavik Tunnel before reaching its terminus at the village of Granvin in Voss Municipality. The portion of the road from Haugestøl to Eidfjord (over the Hardangervidda plateau) is designated a National Tourist Route.
