Ring I (pronounced "ring one", Finnish: Kehä I, Swedish: Ring I) is the busiest of all highways in Finland, carrying up to 113,000 vehicles per day. It is the innermost of the three beltways in the Greater Helsinki region, numbered as regional route 101 and runs from the eastern-most part of Espoo to Itäkeskus in eastern Helsinki. The total length is 24.2 kilometres (15.0 mi), of which 16 km (9.9 mi) are in Helsinki. It is primarily intended for local traffic—before the large road numbering change in the 1990s and the reconstruction of Ring III, Ring I was also designated as a bypass for avoiding Helsinki centre.
