Editing Interstate 605 (section)

==History==
[[File:I605 CA dv 26 north lg.jpg|thumb|Approaching the northern terminus of I-605]]
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 }}</ref>{{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&nbsp;60]]. The newest section (extension to [[Interstate 210 (California)|I-210]]) was opened in 1971 was originally signed as SR&nbsp;243. There are plans to extend it to [[California State Route 1|SR&nbsp;1]] further south in Orange County as SR&nbsp;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}} of I-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>
