Named the Jacob Dekema Freeway after the longtime head of the regional division of the California Department of Transportation, it was completed and open to traffic in 1975. The freeway has been frequently cited for its complex engineering and architecture, including near I-8 on the Mission Valley Viaduct. High-occupancy toll lanes are under construction on both the northern and southern portions of the route.
About Interstate 805 in brief
Interstate 805 is a major north–south auxiliary Interstate Highway in Southern California. It is a bypass auxiliary route of I-5, running roughly through the center of the Greater San Diego region from San Ysidro to near Del Mar. Planning for I-805 began in 1956, and the route was officially designated in 1959 before it was renumbered in the 1964 state highway renumbering. Named the Jacob Dekema Freeway after the longtime head of the regional division of the California Department of Transportation, it was completed and open to traffic in 1975. The freeway has been frequently cited for its complex engineering and architecture, including near I-8 on the Mission Valley Viaduct. High-occupancy toll lanes are under construction on both the northern and southern portions of the route. The route is also part of the National Highway System and the National Freeway and Expressway System, a network of highways that are essential to the country’s economy, defense and mobility by the Federal Highway Administration. In 2013, an average daily traffic of 41,500 at the southern terminus at the Mexico–U.S. border and 262,000 between Bonita Road and SR 54, the latter of which was the highest AADT for the highway for the latter half of the 1950s and 1960s. The original routing for the I-815 was considered for the original Interstate Highway System, which was considered to be the most important highway in the United States at the time of its creation in 1956.
It has been named after Jacob dekema, who helped shape the San Diego freeway system and was the driving force behind the creation of the freeway system in the 1960s and 1970s. It was named after the pioneering traffic engineer and highway planner, who was responsible for the design and construction of several roads and highways in the region, including SR 94, the Martin Luther King Jr. Freeway, SR 15, and SR 163. It ends at the Sorrento Valley neighborhood near the Del Mar city limit, less than a mile north of the Mexican border. It passes through the neighborhoods of North Park, Mission Valley, Clairemont, and University City before terminating at I-4 in San Diego. It then traverses the cities of Chula Vista and National City before reentering San Diego, where it meets SR 52 in Clairemont Mesa. It continues northward through San Diego where it intersects State Route 905 before exiting the city of San Diego and entering Chula Vista. It intersects El Cajon Boulevard before passing under the Hazard Memorial Bridge that carries Adams Avenue. The viaduct is the top stack of the Jack Schrade Interchange over I- 8, which runs along the south side of Mission Valley and is San Diego County’s only symmetrical stack interchange. The San Diego Trolley traffic also runs under the vi aduct on the valley floor. It finally meets its north end at I 5. During the widening project which was completed in 2007, I- 5 was built to be 21 lanes wide.
