Route description

Route 18 currently begins at Route 210 (which as of January 2005 is signed as California State Route 30) and quickly enters the San Bernardino Mountains as a four-lane expressway. The route climbs north at a gentle grade until it turns east, where it begins to offer panoramic views of San Bernardino and the Inland Empire. Hence, this portion of Route 18 is known as the Rim of the World Highway. After meeting California State Route 138 at Crestline, the expressway reverts to a two-lane mountain road. It meets two other highways, California State Route 189 just east of Arrowhead Highlands and California State Route 173 in Lake Arrowhead, before running over California State Route 330 in Running Springs. Route 18 continues through several valleys and near ski resorts before reaching a summit. At that point, Route 18 again runs along a lengthy mountain ridge, offering more spectacular scenery at an even higher elevation. At California State Route 38, Route 18 jogs across a dam and travels along the south shores of Big Bear Lake. After going through the City of Big Bear Lake, it is reverse-multiplexed with Route 38 and moves to the other side of the valley before it descends from the mountains to the desert on the other side, heading east and then north. California State Highway 210, also known as the Foothill Freeway, is a route that runs roughly East-West from Sylmar in the West to San Bernardino in the East. ... An expressway is a divided highway, usually 4 lanes or wider in size, where direct access to adjacent properties has been eliminated. ...
