- This article is an itinerary.
Interstate 5 (I-5) is a United States interstate highway that starts at the border with Mexico in San Ysidro, CA and runs 1381 miles (2223 km) north through the states of California, Oregon and Washington to the border with Canada in Blaine, WA. It serves as an important north-south transportation corridor along the U.S west coast connecting the major cities of San Diego, Los Angeles, Portland, Tacoma and Seattle; the three state capitals of California (Sacramento), Oregon (Salem) and Washington (Olympia); and two additional major cities in neighboring countries (Tijuana & Vancouver) just over the international borders.
Interstate 5 (I-5) replaces the former US Route 99, a north-south route along the west coast. The original U.S. Highway 99 was also known as Pacific Highway which ran 1600mi (2600 km) south from Cache Creek BC through Vancouver, Washington state, Oregon and California and then became Mexico Federal Highway 5 in Calexico/Mexicali. Today I-5 ends at the U.S./Mexican border in San Ysidro where it continues another 1,063 mi (1,711 km) from Tijuana to Cabo San Lucas, through the Baja California peninsula as Mexico Federal Highway 1/1D. Today segments of the old Hwy 99 have been re-numbered as State or Provincial Route 99 (SR-99) in British Columbia, Washington, Oregon and California. Other segments in Washington state have also have been renumbered as SR-11, SR-529 and SR-530; as SR-99E & SR-99W between north Portland and Junction City in Oregon; and SR-111 & SR-86 between Calexico and Palm Desert in California. Some segments of the old Hwy 99 have also been decommissioned altogether as federal and state highways (not numbered) but are still represented by being named "Old Hwy 99" or "Pacific Highway".
There are currently no toll segments on the "Freeway".
Interstate 5 continues north as BC-Hwy 99 to Cache Creek through Vancouver, the Sunshine Coast and Whistler from the Canadian/U.S. border in Blaine, WA and south to Cabo San Lucas through Tijuana and Ensenada in the Baja California Peninsula as Mexico Federal Hwy 1 from the U.S./Mexican border in San Ysidro, CA. I-5 intersects other major US interstate highways diverging to/from different directions such as I-15 and I-8 in San Diego; I-10 in Los Angeles; I-80 in Sacramento; I-84 in Portland; I-90 in Seattle and various three digit interstates (serving as local auxiliary highways), state and U.S highways in the three states it passes through.

The Interstate 5 corridor can be accessed by plane through San Diego, Santa Ana, Burbank, Sacramento, Medford, Portland, Seattle and Bellingham with airports located next to or near the freeway itself. In other cities, such as Los Angeles and Long Beach the airport can be further away (20mi-40mi/32-64km) away from the I-5 corridor on another highway.

Amtrak operates trains "more or less" along the Intestate 5 corridor serving the major west coast cities. Some segments are further away such as the segment from Emeryville to Oxnard in California while other parts of the route are practically next to the freeway itself such as the segment between Longview and Centralia in Washington state. The following routes operate along the I-5 corridor:
- Amtrak Coast Starlight runs once daily between Los Angeles and Seattle via Portland, Klamath Falls, Redding, Sacramento, San Francisco Bay Area, Salinas, Paso Robles, San Luis Obispo, Santa Barbara, Oxnard, Simi Valley and Van Nuys. It runs parallel with the Cascades between Seattle and Eugene with the same stops (except Tukwila, Vancouver WA and Oregon City) and between San Luis Obispo and Los Angeles with the Pacific Surfliner only with fewer stops. (see below)
- Amtrak Cascades... runs between Seattle and Portland 4x daily serving Tukwila, Tacoma, Lacey (Olympia), Centralia and Kelso in Washington state. They run from Seattle to Vancouver via Everett, Stanwood, Mt Vernon & Bellingham 2x daily and from Portland to Eugene via Oregon City, Salem & Albany 2x daily. Additional service from Seattle to Vancouver and from Portland to Eugene are provided on the Amtrak Thruway Bus.

Passengers continue south towards the Mexican border in San Ysidro on the SDMTS 'UC San Diego Blue Line' Trolley from the American Plaza Station, across the street the Santa Fe Station.
- San Joaquins Sacramento, Merced, Stockton, Fresno and Bakersfield. Some trains on this route will go west towards Emeryville and Oakland from Stockton instead of continuing north to Sacramento. This route is then connected to Los Angeles from Bakersfield and from Stockton & Sacramento to Redding by Thruway buses via I-5.

Mile markers are statewide mileposts, starting with "0" at the south border of each state which increases as you go north and then starts over at "0" when crossing the state line into the next state. So going south the numbers on the mileposts will decrease and then start over at the highest number (276 in Washington, 308 in Oregon & 796 in California) when crossing a state line. The exit numbers correspond with the mileposts so some numbers may be skipped if the exits are further apart from one to the next. Other exits that are one next to the other or "2 in 1" may have the same exit number followed by an "A", "B" or even a "C" such as "Exit #100A" to get on A St, "Exit #100B" to get on B St and so forth.
The maximum speed limit is 70 MPH (112 km/h) for cars & 55 MPH (88 km/h) for large trucks on rural stretches and 65 MPH (104 km/h) in urban areas or lower if posted otherwise.

- 9 Basilone Road (Exit 71 / Mile 71.3). There are a handful of fast food restaurants, a commissary, and a single gas station on the east side of the interstate, but these lie behind a gate to Camp Pendleton Marine Base and are thus off-limits to non-military travelers. Less than a mile south of this exit, San Onofre State Beach is publicly accessible and is a popular surfing spot that also offers camping. A short distance further south, the now-decommissioned San Onofre Nuclear Generating Station is visible just west of the interstate; the station's twin spherical containment buildings famously inspired Frank Drebin in The Naked Gun to lament that "everywhere I look something reminds me of her".
Orange County and Los Angeles
Past the Camp Pendleton Marine Base the interstate enters the large conurbation of cities in OC and LA counties. This section is multi-lane (3 to 5) in both directions and is busy with traffic at nearly all times of the day. If at all possible avoid driving at peak commuter times. Some drivers may be tempted to take Interstate 405 as an alternate route, but check traffic conditions before doing so as it is often even worse for traffic congestion.
- San Clemente (Exits 73-77). There are five exits for San Clemente. El Camino Real runs almost parallel to the highway and has a number of restaurants, many but not all Mexican.

- 12 Magic Mountain Parkway (Exit 170 / Mile 170.23). The famous Magic Mountain amusement park is located along the western side of the freeway and is home to roller coasters that have held world records for height and speed; freeway travelers will have an excellent view of thrill seekers taking the plunge over one of the many terrifying hills on the park's iconic rides. There are a number of gas stations, chain restaurants and hotels located right at the exit that cater to park visitors, but expect heavier than normal traffic in the area during the summer when the park is busiest.
The road climbs out of the San Fernando Valley,which although multi-lane will have slow-moving traffic before entering the Santa Clarita Valley. Oddly, at one point the north and south bound carriageways cross and run for a number of miles separate from one another.
- 13 Castaic (Exit 176 / Mile 176.15).
- 14 Tejon Pass Rest Area (Exit 206 / Mile 205.97). Restrooms, water, picnic tables, phone, vending machines and RV sanitation station.

The original route was infamous for its accidents until being straightened and widened between 1933-34. This stretch of road is known as The Grapevine and is often closed during storms when driving conditions become treacherous.
Most of this section is two-lane carriageway in both directions, running straight with only small rises though sparsely populated areas.
- 16 Laval Road (Exit 219A & B / Mile 218.79). The Laval Road exit has undergone dramatic development by the Tejon Ranch Corporation and now offers significant amenities for travelers.

- 17 SR-58 / Buttonwillow / McKittrick (Exit 257 / Mile 257.42). The town of Buttonwillow is actually five miles west of the interstate, but more than enough gas stations, fast food restaurants and even a couple of motels are clustered just off of the east side of the highway. For those heading north, services start to become sparse, so this is a stop worth considering if your gas tank is heading towards empty. Chevron, Mobil, Arco, Shell, and Travel Centers of America are all fuel options, while food options include Starbucks, Denny's, Carl's Jr, McDonald's, Taste of India, and Tita's Pupuseria.

- 20 Twisselman Road (Exit 288 / Mile 287.62). This exit lacks services, but may be worth a stop between October and March to visit the Kern National Wildlife refuge. Located about seven miles east of the interstate, the refuge is a winter home to herons, cranes, hawks, ducks, and many, many other species of birds.
- 21 SR-41 / Kettleman City (Exit 309 / Mile 308.90).

- 23 SR-198 / Lemoore / Hanford (Exit 334 / Mile 333.89). Located in the midst of a long stretch of empty highway, this exit is notable for the Harris Ranch Complex, offering fuel options, food options, a farm stand, a Tesla Supercharger, and lodging. The main ranch building offers a pretty good bakery, and those seeking out a steak won't be disappointed by the restaurant. If long drives aren't your thing, the location is approximately halfway between Los Angeles and San Francisco and thus offers a good place to stop and spend the night. The town of Coalinga is just 13 miles southwest of this exit and has additional amenities.
- 24 John "Chuck" Erreca Rest Area (Exit 386 / Mile 385.83). Restrooms, water, picnic tables, phone and vending machines. No RV sanitation station.
- 25 Highway 33 and 152 / Los Banos (Exit 403 / Mile 402.76). CA-152 west is the main route through the hills to Gilroy and onward to either San Jose (via 101-N) or Monterey Bay (via CA-156). Los Banos, 6 miles east on CA-152, offers amenities for travelers. One exit west (at CA-33) is a Petro station with reasonable restaurant.
- 26 SR-33 / Santa Nella (Exit 407 / Mile 407.02). This exit has several gas stations and a handful of motels. Food options are plentiful and include a Starbucks and an In-N-Out, and for those who have been seeing the many billboards during hours of travel, this is the northern half of the Pea Soup Andersen's chain and its namesake soup.

The Bridge Bay Resort is located just off of the exit at the marina and offers a restaurant and lodging, but the beautiful scenery will be of more interest to most travelers. Houseboats are a popular rental option on the lake, and over one hundred of them can sometimes be seen docked in Bridge Bay.

The maximum rural speed limit is 70 mph (112 km/h) & 60 mph for large trucks which is more relevant along I-84 corridor between The Dalles & the Snake River (Idaho border). The I-5 corridor remains at 65 mph (104km/h) in rural areas and 55-60 mph in urban areas. The stretch of I-5 between Portland & Eugene is also at 55-60mph (88-100km/h) too. Interstate travelers in Oregon should be aware that it is illegal to pump your own gas in the counties through which I-5 passes (although Oregon law changed in 2018 to allow stations in certain counties to offer self-service, I-5 doesn't pass through any of them). When you arrive at a filling station wait for an attendant to come to your car rather than attempting to get out and fill up your car on your own.

Some even offer home baked goods such as brownies too. A donation of any amount is appreciated in the can provided on the counter. Rest stops in Washington state do not have exit numbers but rather marked with a blue sign rather than the green sign.
North of Olympia the interstate enters the large conurbation of cities in Pierce, King and Snohomish counties. This section is multi-lane (3 to 5) in both directions and is busy with traffic at nearly all times of the day. If at all possible avoid driving at peak commuter times. Some drivers may be tempted to take Interstate 405 through Bellevue as an alternate route, but check traffic conditions before doing so as it is often even worse for traffic congestion than Interstate 5.
- 53 I-405/SR-518 (Exit 154). The off ramp splits going west into SR-518 towards Burien and Seattle Tacoma International Airport and east into I-405 towards Renton and Bellevue. The airport can also be accessed from S 188th St from Exit #152.

SR-543 becomes BC-15 after crossing into Canada. There are 4 exits in Blaine.
When on the road, most of the journey is straightforward freeway driving. If it is winter, it is wise to check the weather conditions at the Siskiyou pass before crossing the border from California into Oregon. Snowy conditions are not uncommon, and officials usually close the road if things become too dangerous. A closure can be waited out in the Shasta or Redding area on the California side, or Ashland and Medford on the Oregon side. It is also possible to detour along the coast.
Alternatives for traveling north/south through California include US-Hwy 101, El Camino Real and the Pacific Coast Highway in the west, or US-Hwy 395 along the Eastern Sierra and east of the Cascades in Oregon and Washington. All of these are more scenic and interesting routes but are much longer and slower and are more of a journey to experience than just for getting from A to B. Both SR-99, US-395 and US-Hwy 101 are also local streets/roads at slower speeds through some of the towns they pass through.
