State Route 3, 13 and 15 in California
State Route 3 in California
According to directoryaah, State Route 3 is a state route in the U.S. state of California. The road forms a north-south route through Northern California, from near Peanut to Yreka. State Route 3 is 236 kilometers long.
The road begins near the hamlet of Peanut on State Route 36, halfway between Eureka and Red Bluff. The road heads north through the mountains of Northern California. State Route 3 passes through sparsely populated areas, most places on the route are very small. Roads of any importance are also hardly crossed. The terrain is very mountainous, with many elevation changes. The State Route 3 passes over several mountain passes, the highest of which is almost 1,700 meters high. The highest mountain in the region is the 2,741 meter high Thompson Peak. The road also leads past the reservoir of the Trinity River. The road ends in Yreka, also the largest town on the route, on Interstate 5, about 20 miles south of the Oregon state border.
The road was originally known by several numbers, State Route 3 was created during the major renumbering of 1964. The Trinity Dam was constructed halfway along the route between 1957 and 1962. State Route 3 has been moved over a higher route above the water level of Trinity Lake. State Route 3 has always been a secondary route, there are no larger towns on the route, only terminus Yreka has some regional importance.
Large parts of the route only handle 200 to 500 vehicles per day, only in some places the intensities are a bit higher, such as 3,700 vehicles in Weaverville and 9,400 vehicles in Yreka.
State Route 13 in California
State Route 13 or SR-13 is a state route located entirely within the city of Oakland, California. The highway forms a north-south link in the east of the city, connecting SR-24 with I-580. The road continues into Berkeley as a regular street. The highway section is 8 kilometers long, the entire route is 16 kilometers long. The highway is known as the Warren Freeway.
The highway begins at the interchange with I-580, which runs from San Rafael to Castro Valley. The SR-13 runs more or less parallel to this highway in the city of Oakland. Oakland is one of the larger cities in the Bay Area metropolitan area, with a population of 415,000. The highway runs through the suburbs of this city, and has 2×2 lanes. These neighborhoods are relatively sparsely built-up, and because of the hilly area there is no grid pattern, but the roads are quite winding. The highway portion ends at SR-24, which runs from Oakland to Walnut Creek. After this, the road becomes part of the Berkeley street network, and is called Ashby Avenue. Berkeley is a fairly large city with 103,000 inhabitants. The road ends at Interstate 80, which runs from San Francisco to Sacramento.
State Route 13 was built after State Route 24 opened from Oakland to Walnut Creek to provide a link through eastern Oakland. The first section opened in 1951 in northern Oakland, followed by a longer center section in 1956 and the southeastern section to I-580 in 1966. The original plans envisioned a northwest extension through Berkeley to I-80, and a southward extension through southern Oakland to I-880, forming a bypass of Oakland. This ultimately did not go through. In 1996, the junction with State Route 24 was partially modified.

State Route 15 in California
|Get started||San Diego|
According to ebizdir, State Route 15 is a state route and freeway in the U.S. state of California. The highway forms a north-south route through San Diego and is actually an extension of Interstate 15 in California. The highway is 9 kilometers long.
The highway begins at the San Diego Naval Port as a narrow 2×2 lane highway. The highway continues under Interstate 5, after which the highway has 2×3 lanes through the eastern neighborhoods of San Diego. After two connections, the interchange with State Route 94 follows, after which State Route 15 crosses Interstate 805, the bypass of San Diego. To the north of this, the highway has 2×4 lanes and is sunken with a city park on the highway. The highway then descends sharply and at the intersection with Interstate 8 becomes Interstate 15 to the northern suburbs and Las Vegas.
State Route 15 has a checkered history. The southernmost section of the highway opened in 1954 and is one of the oldest highways in San Diego. This section was important in connection with access to the San Diego Naval Base. In 1960, the northernmost section, no more than a supply to I-8 and I-15 from Adams Avenue, opened. In 1970, a short extension opened from the southern section to the then-opened I-805.
After that, a section through eastern San Diego was missing, which had been planned since the 1960s but whose construction was delayed. This part was ultimately only constructed between 1992 and 2000 as a deepened highway. This missing link opened to traffic in January 2000, completing State Route 15 after 46 years.
The interchange with I-5 opened to traffic in 1978. In 1996, the southern portion of the highway between I-5 and CA-94 was widened to 2×3 lanes.

It is planned to renumber State Route 15 to Interstate 15. The exit numbering is already prepared for this. It is likely that the upgrade will not take place until the State Route 94 junction has been reconstructed.
Every day, 108,000 to 133,000 vehicles drive between I-5 and CA-94 and 126,000 vehicles as far as I-805. The northern section between I-805 and I-8 has 169,000 to 177,000 vehicles per day.
