Frodeåsen
Frodeåsen is a hill just north of the town center of Tønsberg, Norway. Reaching 75 meters (246 ft) above mean sea level, it serves largely as a recreational area.
Two tunnels run through the hill: the 1.75-kilometer (1.09 mi) long Jarlsberg Tunnel of the Vestfold Line and the Frodeåsen Tunnel on County Road 300.
