Interstate 805
Template:Infobox Interstate/Intrastate Interstate 805 (abbreviated I-805, and colloquially referred to as The 805 or the eight-oh-five), is a bypass interstate highway running through the San Diego, California metropolitan area. It is officially known as the Jacob Dekema Freeway after Jacob Dekema, a pioneering force from the California Department of Transportation (Caltrans) who helped shape the San Diego freeway system.

I-805 acts as an alternate bypass route of Interstate 5. The southern terminus of the 805 is at I-5 just a few miles north of the United States–Mexico border at the San Diego district of San Ysidro. I-805 then goes through the cities of Chula Vista and National City before reentering San Diego. The freeway then passes though the San Diego neighborhoods of North Park, Mission Valley, Clairemont, and University City before terminating at I-5 in Sorrento Valley.
Eight to ten lanes throughout, Interstate 805 has evolved into a busy commuter route from the International Border into the exploding South Bay communities of Chula Vista (including Rancho del Rey and Eastlake) and National City. The freeway also leads into the relatively new business parks near University City (via Governor Drive and La Jolla Village Drive) and Sorrento Valley. As more companies locate along the route of Interstate 805, more traffic utilizes the route as an important connector to get from home to work. In addition to commuter traffic, the freeway is one of two north-south freeways that reach Mexico. Traffic to and from the border is also very common along Interstate 805.
The 805 also includes a towering bridge over Mission Valley and Interstate 8, including San Diego County's only symmetrical stack interchange.
State law
History
Plans for the 805 were passed in legislature in 1959 as Legislative Route Number 241. It was approved as a chargeable interstate in 1958, and declared a signed state route in 1964. The freeway was then built between 1970 and 1975.
A major expansion of the 805-5 merge zone was opened to traffic on April 3rd, 2007. Including HOV Lanes and local bypass lanes, this merge spans 22 lanes at the widest point. Work is also underway to add two HOV Lanes between State Route 52 and Mira Mesa Boulevard.
As of 2007, a three-year project is underway to allow robot controlled vehicles, including buses and trucks, to use a special lane. The intention is to allow the vehicles to travel at shorter following distances and thereby allow more vehicles to use the lanes. The vehicles will still have drivers since they need to enter and exit the special lanes. The system is being designed by Swoop Technology, based in San Diego county.[1]
