National Road 23 (Norwegian: Riksvei 23), also known as the Oslofjord Link (Norwegian: Oslofjordforbindelsen), was the name of a 40.2 kilometers (25.0 mi) largely limited-access road which connects the municipalities of Lier, Røyken, Hurum and Frogn in Norway. The 7.2-kilometer (4.5 mi) Oslofjord Tunnel causes the road to acts as the only fixed link crossing of the Oslofjord and makes that section subject to tolls. In 2018 the road was renamed into European route E134.
