Monterey County Route G18 is a 16.40-mile highway aligned over Jolon Road from US Route 101 near Bradley to Monterey County Route G14 in Lockwood. The corridor of Jolon Road is tied heavily to the history of the Spanish El Camino Real and Mission San Antonio de Pauda. Jolon Road was improved during World War II after the creation of Fort Hunter Liggett. Jolon Road was assigned as part of Monterey County Route G18 and Monterey County Route G14 during 1971. The segment of Jolon Road between Bradley-Lockwood now part of Monterey County Route G18 from the March 1943 California Highways & Public Works is featured as the blog cover.
