Its [[odd number]] indicates that it is a north-south highway. Its southern terminus is at the [[United States - Mexico border|international border]] between the [[United States]] and [[Mexico]] in the [[San Diego, California|San Diego]] community of [[San Ysidro, California]]. Its northern terminus is at the [[Canada-United States border|international border]] between the [[United States]] and [[Canada]] at the [[Peace Arch]] in [[Blaine, Washington]]. I-5 is the only Interstate highway to touch both the [[Canada|Canadian]] and [[Mexico|Mexican]] borders. At its southern end, I-5 continues into adjacent [[Tijuana]] as [[Mexico Federal Highway 1]]. On its north side, I-5 continues into [[Vancouver]], Canada as [[British Columbia Highway 99|Highway 99]]. This highway links to [[control cities]] in [[California]] ([[San Diego, California|San Diego]], [[Los Angeles, California|Los Angeles]], [[San Francisco, California|San Francisco]], [[Sacramento, California|Sacramento]], and [[Redding, California|Redding]]), [[Oregon]] ([[Medford, Oregon|Medford]], [[Eugene, Oregon|Eugene]], [[Salem, Oregon|Salem]], and [[Portland, Oregon|Portland]]), and [[Washington]] ([[Tacoma, Washington|Tacoma]], [[Seattle, Washington|Seattle]], [[Everett, Washington|Everett]], [[Mount Vernon, Washington|Mount Vernon]], [[Bellingham, Washington|Bellingham]]). [[Vancouver]], [[British Columbia]], is also a control city on Interstate 5 from the Seattle-Tacoma area to the northern terminus at the Canadian border. Notably, a control city not directly linked by this highway is [[San Francisco, California|San Francisco]], which is about {{convert|80|mi|km}} west of I-5. To the south, [[Interstate 580 (California)|Interstate 580]] splits from I-5 towards San Francisco, while, to the north, [[Interstate 505 (California)|Interstate 505]] cuts south to [[Interstate 80]], which serves that city. That routing, via I-580, I-80 and I-505, was once Interstate 5W.{{Fact|date=April 2007}} Along with [[Interstate 8]], [[Interstate 10]], [[Interstate 15 in California|Interstate 15]], [[Interstate 40 in California|Interstate 40]], and [[U.S. Route 101]], I-5 serves as one of the primary roads that link the [[Greater Los Angeles Area|Los Angeles]]/[[San Diego-Tijuana metropolitan area|San Diego]] Metropolitan areas to the rest of the nation. ==Route description== {{lengths table|length_ref=<ref name="fhwa" />}} |- |[[Interstate 5 in California|CA]] || 796.53 || 1281.89 |- |[[Interstate 5 in Oregon|OR]] || 308.14 || 495.90 |- |[[Interstate 5 in Washington|WA]] || 276.62 || 445.18 |- |Total || 1381.29 || 2222.97 |} {| class="infobox" width="230px" !style="background: #ccf;"|<big>Major cities</big><br><small>'''Bolded cities''' are officially-designated [[control city|control cities]] for signs</small> |- | *'''[[San Diego, California]]''' (southbound) *'''[[Santa Ana, California]]''' *'''[[Los Angeles, California]]''' *'''[[San Francisco, California]]''' (via [[Interstate 580 (California)|I-580]] west, or via [[Interstate 505 (California)|I-505]] south and [[Interstate 80 in California|I-80]] west) *'''[[Stockton, California]]''' *'''[[Sacramento, California]]''' *'''[[Redding, California]]''' *'''[[Mount Shasta City, California]]''' *'''[[Weed, California]]''' *'''[[Yreka, California]]''' *'''[[Ashland, Oregon]]''' *'''[[Medford, Oregon]]''' *'''[[Grants Pass, Oregon]]''' *'''[[Roseburg, Oregon]]''' *'''[[Eugene, Oregon]]''' *[[Albany, Oregon]] *'''[[Salem, Oregon]]''' *'''[[Portland, Oregon]]''' *[[Vancouver, Washington]] *[[Olympia, Washington]] *'''[[Tacoma, Washington]]''' *'''[[Seattle, Washington]]''' *'''[[Everett, Washington]]''' *[[Mount Vernon, Washington]] *[[Bellingham, Washington]] *'''[[Vancouver, British Columbia]]''' (northbound; via [[British Columbia Highway 99|Hwy 99]] north) |} ===California=== {{main|Interstate 5 in California}} The most southerly point of Interstate 5 is at the [[United States-Mexico border]] at the [[San Ysidro, California|San Ysidro]] border crossing, one of the busiest in the world.<ref>[http://www.interstate-guide.com/i-005.html Busiest border crossing]</ref> Beginning at the border in San Ysidro, which is part of the city of [[San Diego]], as the [[John J. Montgomery Freeway]], I-5 goes through the [[suburb]]s of [[National City, California|National City]] and [[Chula Vista, California|Chula Vista]] before reaching downtown [[San Diego, California|San Diego]]. It then parallels the Pacific coastline, going through the northern suburbs of San Diego, bisecting the [[University of California, San Diego]] campus, before passing through the 28 miles (45 km) of [[United States Marine Corps|Marine Corps]] Base [[Camp Pendleton, California|Camp Pendleton]] in northern [[San Diego County, California|San Diego County]]. Here I-5 is also known as the San Diego Freeway. I-5 covers 797 miles in California. At [[Dana Point, California|Dana Point]], I-5 turns inland and heads due north through [[Mission Viejo, California|Mission Viejo]] to the [[El Toro Y]] interchange in southeastern [[Irvine, California|Irvine]]. I-5 becomes the [[Santa Ana Freeway]] as it runs southeast to northwest, passing through major cities and suburbs in [[Orange County, California|Orange]] and [[Los Angeles County, California|Southern Los Angeles]] counties. Angelenos refer to it as "'''the 5'''" or as the Santa Ana Freeway. From this point, the San Diego Freeway continues northward as I-405. When the freeway reaches the [[East Los Angeles Interchange]] one mile (1.6 km) east of downtown [[Los Angeles, California|Los Angeles]], I-5 becomes the [[Golden State Freeway]]. The route continues through the [[San Fernando Valley]] and then crosses the [[Newhall Pass]] through the [[Santa Susana Mountains]] into the [[Santa Clarita Valley]]. For about a four-mile (6 km) stretch between [[Santa Clarita Valley]] and the [[Pyramid Lake (California)|Pyramid Lake]], the northbound and southbound lanes separate and actually invert, with the southbound lanes being to the east of the northbound ones. Beginning at that point, the Golden State Freeway sharply rises to the north through [[Ridge Route#Features|the Grapevine]] to eventually reach the second-highest point of its entire length, the [[Tejon Pass]] (elevation 4,183 ft. (1,275 m)) through the [[Tehachapi Mountains]]. [[Path 26]] [[electric power transmission|power line]]s generally parallel the freeway along this stretch. The freeway then sharply descends for {{convert|12|mi|km}} at Tejon Pass to around {{ft to m|1600}} at Grapevine near the southernmost point of the [[San Joaquin Valley]], approximately {{mi to km|30|abbr=yes}} south of [[Bakersfield, California|Bakersfield]] and {{mi to km|4|abbr=yes}} south from where [[State Route 99 (California)|State Route 99]] splits away from it in [[Wheeler Ridge, California|Wheeler Ridge]]. [[Image:I-5 near Shasta.jpg|thumb|left|I-5 south approaching [[Weed, California|Weed]] and [[Mount Shasta|Mt. Shasta]].]] From Highway 99 to south of [[Tracy, California|Tracy]], I-5 skirts along the far more remote western edge of the great [[Central Valley (California)|Central Valley]], and thus here is removed from population centers such as [[Bakersfield, California|Bakersfield]] and [[Fresno, California|Fresno]] with other state highways providing connections. [[Interstate 580 (California)|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 north through [[Stockton, California|Stockton]] and [[Sacramento, California|Sacramento]] before turning west to [[Woodland, California|Woodland]]. At Woodland, the interstate heads northwest again towards [[Dunnigan, California|Dunnigan]], where it converges with [[Interstate 505]]. From Dunnigan, I-5 skirts north along the western edge of the [[Sacramento Valley]] to [[Red Bluff, California|Red Bluff]]. I-5 then enters the [[Shasta Cascade]] region, passing through [[Redding, California|Redding]] and [[Shasta Lake]] before climbing up to near the foot of [[Mount Shasta]]. The interstate then travels to [[Weed, California|Weed]] and [[Yreka, California|Yreka]] before reaching the Oregon border. ===Oregon=== {{main|Interstate 5 in Oregon}} About {{mi to km|3|abbr=yes}} north of the California border, the highway crosses {{ft to m|4310}} [[Siskiyou Summit]], the highest point on I-5. Dropping down into Rogue River valley through Oregon's southern mountains and towns such as [[Ashland, Oregon|Ashland]], [[Medford, Oregon|Medford]] and [[Grants Pass, Oregon|Grants Pass]]. Turning north across three passes to the Umpqua Valley and through [[Roseburg, Oregon|Roseburg]], the mountains tend to turn into hills, and as it reaches Cottage Grove, the road enters the [[Willamette Valley|Willamette River Valley]]. At Eugene the highway intersects with the short [[Oregon Route 126|Interstate 105]]. The interstate then heads almost due north, skirting [[Albany, Oregon|Albany]] and [[Corvallis, Oregon|Corvallis]], and passes through [[Salem, Oregon|Salem]]. There were plans to build a spur into [[Salem, Oregon]], called [[Interstate 305 (Oregon)|Interstate 305]]. I-5 covers 308 miles in Oregon. [[Image:I5inPortlandNight.jpg|thumb|In downtown Portland, I-5 runs adjacent to the [[Willamette River]] and passes by the [[Rose Garden Arena]] (center), and [[Oregon Convention Center]] (right).]] Just north of Salem, between mile marks 259 and 260, placed in the median is a sign where the 45th parallel crosses I-5. It bears the words "45 Parallel half way between the Equator and the North Pole". The highway then tracks a little to the northeast, [[Interstate 205 (Oregon-Washington)|Interstate 205]] splits off south of the [[Portland, Oregon|Portland]] metro area. From here it passes up through Tualatin and Tigard along former [[U.S. Route 99W (Oregon)|U.S. Route 99W]] before hitting the southern terminus of [[Interstate 405 (Oregon)|I-405]] and the [[Marquam Bridge]]. Also planned was a spur in [[Portland, Oregon|Portland]] off I-405, called [[Interstate 505 (Oregon)|Interstate 505]], but it was never built and has been removed from city plans. A stub of I-505 exists as a long exit ramp to [[U.S. Route 30]]. After crossing the Willamette River on the [[Marquam Bridge]], I-5 has junctions at the western terminus of [[Interstate 84 in Oregon|Interstate 84]] and the northern terminus of I-405. It then continues through the northern parts of the city of Portland, and crosses into Washington via the [[Interstate Bridge]]. [[Image:Nisqually River 05876.JPG|left|thumb|I-5 bridge over the [[Nisqually River]], near Tacoma, Washington]] [[Image:Interstate 5 from Two Union Square.jpg|thumb|right|Interstate 5, looking north from [[Two Union Square]] in [[Seattle, Washington]].]] ===Washington=== {{main|Interstate 5 in Washington}} The highway begins in Washington over the [[Columbia River]] and drops down into the city of [[Vancouver, Washington|Vancouver]]. About seven miles (11 km) into the state, it reaches the northern terminus of [[Interstate 205 (Oregon-Washington)|I-205]], which is on the eastern edge of the Portland-Vancouver metropolitan area. It then tracks north by northwest to [[Kelso, Washington|Kelso]] and [[Longview, Washington|Longview]], at which point it ceases paralleling a large bend of the Columbia. Continuing north through the [[Willapa Hills]], the freeway eventually reaches [[Olympia, Washington|Olympia]], where it bends sharply east, after that it goes through [[Fort Lewis]] and by [[McChord AFB]], then finally [[Tacoma, Washington|Tacoma]] where it bends sharply north again to reach [[Seattle, Washington|Seattle]]. The [[Ship Canal Bridge]] carries it over [[Portage Bay]] in Seattle. The freeway makes its way out of the Seattle/Tacoma/[[Everett, Washington|Everett]] metro area, crosses the floodplains of three rivers, through the Skagit Valley and the Mount Vernon-Anacortes Metropolitan Area to the northern city of [[Bellingham, Washington|Bellingham]] to arrive at the [[Peace Arch]] Canadian border crossing between [[Blaine, Washington]], and [[Surrey, British Columbia]]. [[British Columbia Highway 99|Highway 99]] continues northwesterly from the border into [[Vancouver|Vancouver, B.C.]] I-5 covers 277 miles in Washington. ==History== An extensive section of this highway (over {{convert|600|mi|km}}), from approximately [[Stockton, California]], to [[Portland, Oregon]], follows very closely the track of the [[Siskiyou Trail]].<ref name="siskiyou">[http://www.museumsiskiyoutrail.org Museum of the Siskiyou Trail]</ref> The Siskiyou Trail was based on an ancient network of [[Native Americans in the United States|Native American]] footpaths connecting the [[Pacific Northwest]] with California's [[Central Valley (California)|Central Valley]]. By the 1820s, trappers from the [[Hudson's Bay Company]] were the first non-Native Americans to use the route of today's I-5 to move between today's Washington State and California. During the second half of the 19th century, mule trains, stagecoaches, and the [[Central Pacific]] railroad also followed the route of the Siskiyou Trail.<ref name="siskiyou">[http://www.museumsiskiyoutrail.org Museum of the Siskiyou Trail]</ref> By the early 20th century, pioneering automobile roads were built along the path of the Siskiyou Trail, notably the [[Pacific Highway (US)|Pacific Highway]]. The Pacific Highway ran from [[British Columbia]] to [[San Diego, California]], and was the immediate predecessor of much of [[U.S. Route 99]]. The route of U.S. 99 was in turn used as a basis for much of the route of today's I-5. In 1988, smoke from nearby [[field burning]] caused a 23-car pileup near [[Albany, Oregon]], leading to 7 deaths and 37 injuries. This accident resulted in more regulation of field burning. <ref> http://extension.oregonstate.edu/oap/story.php?S_No=72&storyType=oap&cmd=pf</ref> ==Major intersections== [[Image:I-90 and I-5 cloverleaf seattle washington.jpg|thumb|right|Interstate 5 and [[Interstate 90]] meeting in [[Seattle, Washington]].]] *[[Interstate 805 (California)|Interstate 805]] (bypass) in south [[San Diego, California]] *''[[Interstate 15 in California|Interstate 15]] in [[San Diego, California]] (future; this freeway is currently signed as [[California State Route 15|State Route 15]])'' *[[Interstate 8]] in [[San Diego, California]] *[[Interstate 805 (California)|Interstate 805]] (bypass) in north [[San Diego, California]] *[[Interstate 405 (California)|Interstate 405]] (bypass) at the [[El Toro Y]] in [[Irvine, California]] *[[Interstate 605]] in [[Santa Fe Springs, California]] *[[Interstate 710 (California)|Interstate 710]] southeast of downtown [[Los Angeles, California]] *[[Interstate 10]] at the [[East Los Angeles Interchange]] complex, east of downtown [[Los Angeles, California]] *[[Interstate 405 (California)|Interstate 405]] (bypass) in [[Sylmar, California]] *[[Interstate 210 (California)|Interstate 210]] in Sylmar, California *[[Interstate 580 (California)|Interstate 580]] in [[Tracy, California]] *[[Interstate 205 (California)|Interstate 205]] in Tracy, California *[[Interstate 305]] in [[Sacramento, California]] (hidden, known as [[Business Loop 80]].) *[[Interstate 80]] in [[Sacramento, California]] *[[Interstate 505 (California)|Interstate 505]] in [[Dunnigan, California]] *[[Oregon Route 126|Interstate 105]] in [[Eugene, Oregon]] *[[Interstate 205 (Oregon)|Interstate 205]] (bypass) in [[Tualatin, Oregon]] (southern junction) *[[Interstate 405 (Oregon)|Interstate 405]] (bypass) in [[Portland, Oregon]] (southern junction) *[[Interstate 84 in Oregon|Interstate 84]] in [[Portland, Oregon]] *[[Interstate 405 (Oregon)|Interstate 405]] (bypass) in [[Portland, Oregon]] (northern junction) *[[Interstate 205 (Oregon)|Interstate 205]] (bypass) in [[Salmon Creek, Washington]] (northern junction) *[[Interstate 705]] in [[Tacoma, Washington]] *[[Interstate 405 (Washington)|Interstate 405]] (bypass) in [[Tukwila, Washington]] (southern junction) *[[Interstate 90]] in [[Seattle, Washington]] *[[Interstate 405 (Washington)|Interstate 405]] (bypass) in [[Lynnwood, Washington]] (northern junction) ==Auxiliary routes== *[[San Diego, California]] - [[Interstate 805|I-805]] *[[San Diego, California]] - [[Interstate 905|I-905]] (future) *[[Los Angeles, California]] - [[Interstate 105 (California)|I-105]] *[[Los Angeles, California]] - [[Interstate 605|I-605]] *[[Los Angeles, California|Los Angeles]] and [[Orange County, California]] - [[Interstate 405 (California)|I-405]] *[[Tracy, California]] - [[Interstate 205 (California)|I-205]] *[[Sacramento, California]] - [[Interstate 305 (California)|I-305]] (unsigned) *[[Zamora, California]] - [[Interstate 505 (California)|I-505]] *[[Eugene, Oregon]] - [[Oregon Route 126|I-105]] *[[Portland, Oregon]] - [[Interstate 405 (Oregon)|I-405]] *[[Portland, Oregon]] and [[Vancouver, Washington]] - [[Interstate 205 (Oregon)|I-205]] *[[Tacoma, Washington]] - [[Interstate 705 (Washington)|I-705]] *[[Seattle, Washington]] - [[Interstate 405 (Washington)|I-405]] I-5 will have a complete set of auxiliary routes (105, 205, 305...805, 905), with the completion of [[Interstate 905]] in San Diego.
