Route 1 or the Ring Road (Icelandic: Þjóðvegur 1 or Hringvegur) is a national road in Iceland that runs around the island and connects most of the inhabited parts of the country.
The total length of the road is 828 miles. Some of the most popular tourist attractions in Iceland, such as the waterfalls Seljalandsfoss and Skógafoss, and Jökulsárlón glacier lagoon, are also on or near the Ring Road.
For almost all its length, the road is two lanes wide: one lane going in each direction. Many smaller bridges are single lane, specially in eastern Iceland, and constructed of wood and/or steel.
The road is paved with asphalt for most of its length, but there are still stretches with an unpaved gravel surface. Although paved, some portions of the road are still the original 1940s country roads, and contain hazards such as blind curves and blind summits, single lane bridges, and narrow passes.
