U.S. stateof California, Interstate 5, a major north-south route of the Interstate Highway System, has its southern terminus at the United States-Mexico borderat the San Ysidro crossing. It heads north across the length of Californiabefore it crosses into Oregonsouth of the Medford-Ashland metropolitan area.
This highway links the major California cities of San Diego, Los Angeles, Sacramento, and Redding. Among the major cities not directly linked by Interstate 5 is
San Francisco, which is about 80 miles (130 km) west of the highway.
This route is part of the
California Freeway and Expressway System[http://www.leginfo.ca.gov/cgi-bin/displaycode?section=shc&group=00001-01000&file=250-257 CA Codes (shc:250-257)] ] and is eligible for the State Scenic Highway System [http://www.leginfo.ca.gov/cgi-bin/displaycode?section=shc&group=00001-01000&file=260-284 CA Codes (shc:260-284)] ] .
Interstate 5 starts at the
United States-Mexico borderat the San Ysidro border crossing, one of the busiest in the world. [ [http://www.interstate-guide.com/i-005.html Busiest border crossing] ] Interstate 5 meets Mexican Federal Highway 1at the border with Baja California, and this highway is the toll road from Tijuanato Ensenada. Interstate 805 begins here, bypassing the bulk of the San Diego metropolitan area.
At Dana Point, I-5 turns inland and heads due north through Mission Viejo to the
El Toro Yinterchange in southeastern Irvine. From that point, Interstate 405 takes over the San Diego Freeway designation, while I-5 becomes the Santa Ana Freewayas it runs southeast to northwest, passing through major cities and suburbs in Orange and Southern Los Angeles counties.
When the freeway reaches the
East Los Angeles Interchangeone mile (1.6 km) east of downtown Los Angeles, I-5 becomes the Golden State Freeway. The route continues through the San Fernando Valleyand then crosses the Newhall Passthrough the Santa Susana Mountainsinto the Santa Clarita Valley. From there, the Golden State Freeway sharply rises to the north through the Grapevine to eventually cross the Tejon Passthrough the Tehachapi Mountainswith Path 26power lines generally paralleling the freeway. The freeway then sharply descends for 12 miles (19 km) from over 4,100 feet (1,250 m) at Tejon Pass to around 1,600 feet (488 m) at Grapevine near the southernmost point of the San Joaquin Valley, approximately 30 miles (50 km) south of Bakersfield and 4 miles (6 km) south from where State Route 99 splits away from it in Wheeler Ridge.
Central and Northern California
From Highway 99 to south of Tracy, I-5 parallels Highway 33, skirting along the far more remote western edge of the great Central Valley, and thus here is removed from population centers such as Bakersfield and Fresno with other state highways providing connections. For most of this section, the
Path 15electrical transmission corridor follows the highway, forming an infrastructure corridor along with the California Aqueduct.
Interstate 580 splits off from I-5 at a point south of Tracy, providing a loop-route connection to the
San Francisco Bay Area. After passing Tracy, I-5 heads due north through Stockton and Sacramento before turning due west to Woodland. At Woodland, the interstate heads northwest again towards Dunnigan, where it converges with Interstate 505.
From Dunnigan, I-5 skirts north along the western edge of the
Sacramento Valleyto Red Bluff. I-5 then enters the Shasta Cascaderegion, passing through Redding and Shasta Lakebefore climbing up to near the foot of Mount Shasta. The interstate then travels to Weed and Yreka before reaching the Oregon border.
Historical naming in California
The portion of this highway from
Los Angeles, to San Diego, was also co-signed as U.S. Route 101 until late 1964.
California, the former western branch of Interstate 5 (the northern end of the spur into the Bay Area) connecting Interstate 80 out of Vacaville to near Dunnigan, previously known as Interstate 5W, was renamed Interstate 505. Interstate 580 running between I-5 and I-80 was also once designated 5W; what is now I-5 (the stretch that runs through Sacramento) had been originally designated Interstate 5E.
October 12, 2007 tunnel fire

'Boat Section' repair
Repair of the "Boat Section" in Sacramento began in May 2008. The construction was to take 40 days to complete and would require complete northbound and southbound closures on an alternating schedule. This section had major problems since being built, including being flooded in convert|15|ft|m of water in 1980.

postmiles were measured in 1964, based on the alignment as it existed at that time, and do not necessarily reflect current mileage. The numbers reset at county lines; the start and end postmiles in each county are given in the county column."
