Editing Roundabout (section)

===Sub-sea roundabouts===
A new development is the roundabout below the seabed, in locations where multiple undersea traffic tunnels join. The first such roundabout is in the Eysturoy Tunnel ([[Eysturoyartunnilin]]), opened in December 2020 in the [[Faroe Islands]]. It connects the main island [[Streymoy]] with two locations on the island [[Eysturoy]] that are separated by a long fjord, [[Skálafjørður]]. So, three roads meet at this roundabout. Total length of the system is 11.24 km (6.98 mi). It was the largest ever infrastructure project in the Faroe Islands, estimated to have cost around a billion Danish kroner.<ref>For sources and references see the [[Eysturoyartunnilin|separate article]] on this tunnel and its roundabout.</ref>
