Travel directions

State Route 45/162 between Codora and Glenn.

State Route 45 traverses part of the Sacramento Valley north of the California capital Sacramento and runs parallel to the Sacramento River. The road is a quiet single carriageway through flat and agricultural area. Most places on the route are very small, only Colusa has something of a center function. The road runs parallel to Interstate 5 about 15 miles away.


State Route 45 has historically been of secondary importance, the original north-south connection through the Sacramento Valley was US 99, later State Route 99. While State Route 45 runs directly along the Sacramento River, it doesn’t reach any sizeable place. Later in 1965-1973, I-5 was built parallel west of State Route 45 as a freeway and handles through traffic through the region.

Traffic intensities

Most parts of State Route 45 drive 1,000 to 2,000 vehicles per day, dipping at 500 vehicles near Grimes and peaking at 6,900 vehicles in Colusa.

State Route 46 is a state route in the U.S. state of California. The road forms an east-west route through the center of the state, from the coast at Cambria to Famoso in the San Joaquin Valley. Various parts are a 2×2 divided highway. State Route 46 is 178 kilometers long.

Travel directions

South of Cambria, State Route 46 begins at an intersection with State Route 1 near the Pacific Ocean. The road leads inland as a quiet two-lane road and runs over a 600 meter high mountain pass. Then you reach a valley in which the town of Paso Robles is located. State Route 46 is a short stretch here with US 101 double-numbered, which is run as a freeway. From Paso Robles to the east, State Route 46 is constructed as a 2×2 divided highway. The road leads through a low mountain range that is quite dry, after which you enter the San Joaquin Valley. First at Lost Hills one crosses Interstate 5, after which the road runs past Wasco and at Famoso on State Route 99ends.


James Dean Memorial Intersection with SR-41.

The road was largely constructed and asphalted in the 1920s and 1930s. The road was originally a US Highway, US 466. In 1964, many US Highways in California were scrapped, including US 466, since then the road has been numbered State Route 46.

The intersection with SR-41 became famous for an accident that killed actor James Dean in 1955. The intersection is now called the James Dean Memorial Junction.

State Route 46 originally began in Paso Robles. In the 1970s, the two-lane highway between SR-1 and US 101 was built west of Paso Robles. The section between Paso Robles and the I-5 was later largely widened to 2×2 divided highway, according to the MUTCD this type of road is called an expressway, although the road is not grade separated. The first double-lane section was the Paso Robles bypass, which was widened to 2×2 lanes before 1994. Around 2010, the portion in the San Joaquin Valley to Lost Hills was widened to 2×2 lanes. Between 2009 and 2014, the section between Paso Robles and Shandon was widened to 2×2 lanes. The project was fully completed in 2015. In 2022, the doubling of the road east of Shandon to SR-41 will begin.

Traffic intensities

Every day, 3,300 vehicles travel on the western portion between State Route 1 and US 101, increasing to a maximum of 25,000 vehicles on the Paso Robles perimeter road. The portion from Paso Robles to State Route 41 has 13,000 vehicles, then drops to 6,000 to 9,000 vehicles further to I-5. 6,000 vehicles run between I-5 and Wasco, peaking at 18,000 vehicles in Wasco and 9,000 vehicles further up to State Route 99.

State Route 47 or SR-47 is a state route and freeway in the U.S. state of California. Located in the port area of ​​the Los Angeles metropolitan area, the highway connects Terminal Island to the city’s mainland. The route is 5 kilometers long.

Travel directions

The Vincent Thomas Bridge.

The highway begins in the San Pedro neighborhood of Los Angeles, at the intersection where Interstate 110 begins. I-110 is the Harbor Freeway, and runs to downtown Los Angeles. SR-47 runs east, over the container ports of Los Angeles, via the Vincent Thomas Bridge, a suspension bridge. The highway has 2×2 lanes here. One then comes across Terminal Island, one of the largest container ports in the United States. There are a few at-grade intersections on Terminal Island, and SR-47 turns north halfway through, while straight ahead is the connecting road to Interstate 710. Via a lift bridge you then reach the mainland of California, in the Wilmington neighborhood. The highway here is called the Terminal Island Freeway, and has 2×2 lanes. The road ends at Sepulveda Boulevard, on the border of Los Angeles and Long Beach.


The road had already been built in 1924 as a truck route from the ports to Compton. In 1948, the Heim Bridge opened over part of the dock area north of I-710. This lift bridge was built by the US Navy. In 1963 the much larger Vincent Thomas Bridge opened, a toll bridge until 2000. In 1970 the bridge was connected to Interstate 110.

The Terminal Island Freeway does not have HOV lanes due to its relatively low importance, low traffic volumes and the fact that the highway has mostly only 2×2 lanes. HOV lanes are also not planned.
