'''Interstate |
'''Interstate 605''' (abbreviated '''I-605''', officially known as the '''San Gabriel River Freeway''') is a {{convert|27|mi|km|adj=mid|-long}} major north–south [[List of auxiliary Interstate Highways|auxiliary Interstate Highway]] in the [[Greater Los Angeles]] urban area of [[Southern California]]. It runs from [[Interstate 405 (California)|I-405]] and [[California State Route 22|State Route 22]] (SR 22) in [[Seal Beach, California|Seal Beach]] in [[Orange County, California|Orange County]] to [[Interstate 210 (California)|I-210]] just south of the [[Irwindale, California|Irwindale]]–[[Duarte, California|Duarte]] border in [[Los Angeles County, California|Los Angeles County]]. The San Gabriel River Freeway closely parallels the [[San Gabriel River (California)|San Gabriel River]] for most of its alignment, hence its name, which is one of the few [[Southern California freeways]] not named after a city along its route. |
||
|
Aside from changes to the interchange with I-105 (which did not open until the early 1990s), and the addition of an HOV lane between I-405 and I-10, I-605 is one of the only remaining freeways that kept its original alignment throughout its run through Los Angeles County since it first opened. |

The southern terminus of I-605 is at the [[Interstate 405 (California)|San Diego]] ([[Interstate 405 (California)|I-405]]) and Garden Grove ([[California State Route 22| |
The southern terminus of I-605 is at the [[Interstate 405 (California)|San Diego]] ([[Interstate 405 (California)|I-405]]) and Garden Grove ([[California State Route 22|SR 22]]) Freeways in [[Seal Beach, California|Seal Beach]]. From there, it runs roughly north through the [[Gateway Cities]] of the [[Los Angeles Basin]]. It then shifts north-northeast, crossing the [[Whittier Narrows]] and across the [[San Gabriel Valley]]. I-605 then ends at its junction with the [[Foothill Freeway]], ([[Interstate 210 (California)|I-210]]) just south of the [[Irwindale, California|Irwindale]]–[[Duarte, California|Duarte]] border. Ramps from I-605 then extend north to [[Huntington Drive]] in Duarte. |
||
I-605 follows most of the length of the [[San Gabriel River (California)|San Gabriel River]] from the San Diego Freeway in Seal Beach to the [[Santa Fe Dam Recreation Area|Santa Fe Dam]]. Typically dry riverbed and flood basins are visible from many portions of the route, especially near the northern terminus. |

In the mid 2000s, a [[HOV lane]] was added for motorists with two or more people to use between I-405 and I-10. The HOV lane ends at I-10and there are no plans to extend it to I-210 at this time. With the addition of the HOV lane, the left shoulder was eliminated to avoid massive costs to widen the freeway. The highway also suffers from traffic jams regularly, especially the junction with [[Interstate 5 inCalifornia|I-5]] (the [[Santa Ana Freeway]]). Newer signs with exit numbers replaced the older signs between the Orange County line and I-10 in 2016, with the completion of the I-605 and I-10 junction improvement. I-605 is one of the only Southern California freeways without destinations ([[control cities]]) such as "[[Seal Beach, California|Seal Beach]]" or "[[Irwindale, California|Irwindale]]" since its opening. Rather, cardinal directions ("NORTH" or "SOUTH"), and a simple "THRU TRAFFIC" designation in place of control cities, are used on signs along I-605 itself. |

In 1957, the number for this route was proposed as I-13, as it is positioned approximately midway between I-5 and I-15 (although it intersects the former). That number was rejected, as was the second proposed number, I-102. Finally, the designation I-605 was accepted in 1958.<ref name="CAHwys">{{cite web |url=http://www.cahighways.org/466-740.html#605 |title=Interstate 605 |last=Faigin |first=Daniel |work=California Highways |access-date=September 23, 2016 }}{{Unreliable source?|date=January 2020}} |

I-605 began construction in 1963 and the first section was opened in 1964 from [[Interstate 405 (California)|I-405]] to [[California State Route 60|SR 60]]. The newest section (extension to [[Interstate 210 (California)|I-210]]) was opened in 1971 was originally signed as SR 243. There are plans to extend it to [[California State Route 1|SR 1]] further south in Orange County as SR 605, but strong community opposition means that it is unlikely that the alignment will ever be built.<ref name="CAHwys" /> |

In 2020, there was a proposal to widen I-605, which would have added four new lanes to {{Convert|12|mi|km|abbr=on}}ofI-605 between [[Norwalk, California|Norwalk]] and [[El Monte, California]]. This proposal was rejected due to strong community opposition, in particular due to the fact that it would have led to the destruction of houses in [[Downey, California]].<ref>{{Cite web|date=2020-10-22|title=Metro Board Unanimously Approves Motion to Delay 605/5 Freeway Widening and Instead Study Alternatives|url=https://la.streetsblog.org/2020/10/22/metro-board-unanimously-approves-motion-to-delay-605-5-freeway-widening-and-instead-study-alternatives/|access-date=2020-12-08|website=Streetsblog Los Angeles|language=en-US}}</ref> |

Interstate 605 (abbreviated I-605, officially known as the San Gabriel River Freeway) is a 27-mile-long (43 km) major north–south auxiliary Interstate Highway in the Greater Los Angeles urban area of Southern California. It runs from I-405 and State Route 22 (SR 22) in Seal BeachinOrange CountytoI-210 just south of the Irwindale–Duarte border in Los Angeles County. The San Gabriel River Freeway closely parallels the San Gabriel River for most of its alignment, hence its name, which is one of the few Southern California freeways not named after a city along its route.
Aside from changes to the interchange with I-105 (which did not open until the early 1990s), and the addition of an HOV lane between I-405 and I-10, I-605 is one of the only remaining freeways that kept its original alignment throughout its run through Los Angeles County since it first opened.
The California Streets and Highways Code defines Route 605 as "(a) Route 1 near Seal Beach to Route 405. (b) Route 405 to Route 210 near Duarte." However, the portion in subsection A has yet to be constructed.
The southern terminus of I-605 is at the San Diego (I-405) and Garden Grove (SR 22) Freeways in Seal Beach. From there, it runs roughly north through the Gateway Cities of the Los Angeles Basin. It then shifts north-northeast, crossing the Whittier Narrows and across the San Gabriel Valley. I-605 then ends at its junction with the Foothill Freeway, (I-210) just south of the Irwindale–Duarte border. Ramps from I-605 then extend north to Huntington Drive in Duarte.
I-605 follows most of the length of the San Gabriel River from the San Diego Freeway in Seal Beach to the Santa Fe Dam. Typically dry riverbed and flood basins are visible from many portions of the route, especially near the northern terminus.
In the mid 2000s, a HOV lane was added for motorists with two or more people to use between I-405 and I-10. The HOV lane ends at I-10 and there are no plans to extend it to I-210 at this time. With the addition of the HOV lane, the left shoulder was eliminated to avoid massive costs to widen the freeway. The highway also suffers from traffic jams regularly, especially the junction with I-5 (the Santa Ana Freeway). Newer signs with exit numbers replaced the older signs between the Orange County line and I-10 in 2016, with the completion of the I-605 and I-10 junction improvement. I-605 is one of the only Southern California freeways without destinations (control cities) such as "Seal Beach" or "Irwindale" since its opening. Rather, cardinal directions ("NORTH" or "SOUTH"), and a simple "THRU TRAFFIC" designation in place of control cities, are used on signs along I-605 itself.
I-605 is part of the California Freeway and Expressway System,[3] and is part of the National Highway System,[4] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[5] I-605 from I-405 to I-10 is known as the San Gabriel River Freeway, as named by Senate Bill 99, Chapter 1101 in 1967.[6]
In 1957, the number for this route was proposed as I-13, as it is positioned approximately midway between I-5 and I-15 (although it intersects the former). That number was rejected, as was the second proposed number, I-102. Finally, the designation I-605 was accepted in 1958.[7][unreliable source?]
I-605 began construction in 1963 and the first section was opened in 1964 from I-405toSR 60. The newest section (extension to I-210) was opened in 1971 was originally signed as SR 243. There are plans to extend it to SR 1 further south in Orange County as SR 605, but strong community opposition means that it is unlikely that the alignment will ever be built.[7]
In 2020, there was a proposal to widen I-605, which would have added four new lanes to 12 mi (19 km) of I-605 between Norwalk and El Monte, California. This proposal was rejected due to strong community opposition, in particular due to the fact that it would have led to the destruction of houses in Downey, California.[8]
