|Get started||San Diego|
According to ACT-TEST-CENTERS, Interstate 805 or I -805 is an Interstate Highway in the US state of California. The highway forms an eastern bypass of San Diego, and is an alternative to Interstate 5, which runs past downtown San Diego. The highway passes through the suburbs of Chula Vista and National City, but runs most of the way through the major city of San Diego itself. The highway is also called Jacob Dekema Freeway, and is 46 kilometers long.
I-805 at I-8.
The highway begins as a split from Interstate 5, just north of the border with Mexico. The highway then has 2×3 lanes, and runs parallel to I-5 to the north. One intersects here with SR-905, which runs east-west parallel to the Mexican border. You then arrive at Chula Vista, the suburb of 228,000 inhabitants that divides San Diego into two parts. Here the highway already has 2×4 lanes. On the north side of Chula Vista, one crosses SR-54, the South Bay Freeway, which runs inland from the coast. This is followed by National City, a suburb of 54,000 inhabitants. There are 2×5 lanes here. There is a junction on the north side of National City, which leads directly to a dead end at 43rd Street in San Diego. This may have once become a freeway to I-5, which runs about 4 kilometers to the west. The highway runs through the older neighborhoods surrounding downtown San Diego, and is more or less naturally sunken. About six kilometers east of downtown, it crosses SR-94, which runs from downtown to the eastern suburbs.
Barely a mile further on, it crosses Interstate 15, which runs from San Diego to Las Vegas. After a short canyon, you will find the neighborhoods built in a grid model, northeast of the center. After this, a short distance descends 100 meters to the next canyon, where one crosses Interstate 8, which runs from San Diego to Yuma in Arizona. It re-enters a canyon, and crosses SR-163, the Cabrillo Freeway, which runs to the northeastern neighborhoods. West of the highway are residential areas, while east of it is San Diego’s largest business park, which is served by 4 highways. One of them is crossed, the SR-54, which runs from the La Jolla neighborhood to Santee. In another business park, I-805 rejoins Interstate 5, which continues to Los Angeles.
The highway was built from 1970 to 1975. The first section opened north of I-15. The northern part opened fairly quickly in 1972, the southern part opened in phases between 1971 and 1975. The point where I-805 and I-5 rejoin in the north was greatly improved in 2007, and now has 22 lanes at its widest point. The highway is rapidly congesting through the fast-growing suburb of Chula Vista and a number of eastern suburbs.

Jacob Dekema Freeway
According to LIUXERS.COM, the highway network of San Diego was built under the direction of the Dutchman Jacob Dekema (1915-2017), born in Java to Dutch parents. He was the leader of District 11 of Caltrans between 1955 and 1980, during which time 95% of the freeways in the San Diego area were built. He graduated from the University of Southern California in 1937. He then worked at Caltrans, but served in the Navy during World War II. He worked for Caltrans in various counties of California after the war. In 1955 he was put in charge of District 11, which at the time had 40 kilometers of freeway. During his leadership from 1955 to 1980, that grew to 820 kilometers. In 1982, I-805 was named after him, the Jacob Dekema Freeway. He passed away in April 2017 at the age of 101.
On March 5, 2014, HOV lanes opened along I-805 between SR-54 and SR-94 for five miles. The highway has been widened from 2×4 to 2×5 lanes. Between February 2013 and early 2016, a 5-kilometer HOV lane was constructed in both directions between SR-52 and Mira Mesa Boulevard . This project cost $86 million. The highway has been widened to 2×5 lanes.
Express lanes are planned for virtually all of I-805, with 2×2 toll lanes in the median strip.
