- The Interstate 605 number is also used for a planned bypass of Seattle, Washington.
The San Gabriel River Freeway is the name assigned to Interstate 605, a major north-south freeway of about 27 miles (43 km) in length located entirely within Southern California, USA. Unlike most other freeways in California which are named after a particular city along its route, this freeway derives its name from the San Gabriel River that it parallels for most of its alignment, though most commuters simply refer to it as the Six-O-Five.
The route
Interstate 605/San Gabriel River Freeway (highlighted in red)
The north terminus of the freeway is at the junction with the Foothill Freeway, (I-210) in Duarte, California, a small city located at the foothills of the San Gabriel Mountains. The alignment of the freeway is generally south-southwest and passes through the San Gabriel Valley, shifting straight south as it crosses the Whittier Narrows into the Los Angeles Basin. After traveling through the Gateway Cities region of southeastern Los Angeles County, it crosses Coyote Creek into Orange County, where it terminates at the junction of the San Diego (I-405) and Garden Grove (CA/SR-22) Freeways in Seal Beach.
Interesting facts
- The freeway follows most of the length of the San Gabriel River, beginning at the Santa Fe Dam and ending at I-405 near Seal Beach. Typically dry riverbed and flood basins are visible from many portions of the route, especially near the Northern terminus.
- The numbering for this route was originally suggested as I-13, as it is positioned approximately midway between I-5 and I-15 (although it intersects the former).
- Signs at entrances and freeway junctions do not include destinations ("control cities") such as "Seal Beach" or "Duarte" but simply read "NORTH" or "SOUTH" — a rarity in Southern California. The control city is often derisively referred to as "THRU TRAFFIC".
- Features a carpool lane.
