State Route 67 (SR 67) is a state highway in San Diego County, California. It begins at Interstate 8 (I-8) in El Cajon and continues to Lakeside as the San Vicente Freeway before becoming an undivided highway through the eastern part of Poway. In the town of Ramona, the route turns into Main Street before ending at SR 78. SR 67 provides direct access from the city of San Diego to the East County region of San Diego County, including Ramona and Julian. The route has existed as a railroad corridor since the turn of the 20th century. A highway known as the Julian road was built by 1913, and was designated as Legislative Route 198 in the state highway system by 1935. Route 198 was renumbered SR 67 in the 1964 state highway renumbering. A freeway south of Lakeside was built in the late 1960s, and opened to traffic in 1970. Since then, the portion of the highway north of Lakeside has become known for a high number of traffic accidents and related fatalities. The California Department of Transportation (Caltrans) has made several attempts to remedy the problem and make the road safer. ==Route description== SR 67 begins at I-8 in El Cajon; known as the San Vicente Freeway, it turns north near the Westfield Parkway shopping center. There are two interchanges in the city of El Cajon: one with Broadway and Fletcher Parkway, and another with Bradley Avenue. Following this, the freeway leaves the El Cajon city limits, entering the city of Santee near Gillespie Field, before coming to an interchange with the eastern end of SR 52 in Santee. Near the Woodside Avenue exit, SR 67 turns northeast, paralleling the San Diego River and entering the unincorporated area of Eucalyptus Hills as it leaves the San Diego urban area. Riverford Road and Winter Gardens Boulevard have interchanges with SR 67.〔 The freeway ends, and SR 67 turns north and becomes an undivided highway at Mapleview Street, crossing the San Diego River and entering the locale of Moreno. SR 67 then enters the rural area east of Sycamore Canyon County Open Space Preserve near the locale of Foster, passing to the west of San Vicente Reservoir. The road intersects the eastern end of Scripps Poway Parkway and County Route S4 (CR S4), the latter within the Poway city limits. In eastern Poway, SR 67 veers east, eventually leaving the city and entering unincorporated Rock Haven. The road continues near Rosemont before turning northeast and becoming Julian Road and then Main Street in downtown Ramona. SR 67 ends at the intersection with SR 78; SR 78 intersects to the northwest as Pine Street and continues northeast along Main Street towards Julian. SR 67 is part of the California Freeway and Expressway System, but is not part of the National Highway System, a network of highways that are essential to the country's economy, defense, and mobility. The route is named the CHP Officer Christopher D. Lydon Memorial Freeway from I-8 to Mapleview Street in Lakeside. In 2013, SR 67 had an annual average daily traffic (AADT) of 94,000 between Broadway and Bradley Avenue (the highest AADT for the highway), and 18,100 between Rio Maria Road and Poway Road (the lowest AADT for the highway). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「California State Route 67」の詳細全文を読む スポンサード リンク
