Route description
[edit]The southern terminus of I-505 is at I-80 next to theNut Tree Airportin theNut Treearea inVacaville.From there, it travels north about 10 miles (16 km) through rural areas near the western edge of theSacramento Valleybefore reachingWinters.I-505 then skirts the easterncity limitsof Winters, intersecting withState Route 128—the only exit in Winters. After leaving that city, the Interstate then proceeds north through rural areas again for about 20 miles (32 km) until it reaches its northern terminus with I-5 nearDunnigan.
For its entire length, I-505 is a four-lane freeway (two lanes in each direction) with a maximum speed limit of 70 mph (110 km/h), which is typical for rural Interstates in California.
I-505 is part of theCalifornia Freeway and Expressway System,[2]and is part of theNational Highway System,[3]a network of highways that are considered essential to the country's economy, defense, and mobility by theFederal Highway Administration.[4]
History
[edit]What is now I-505 was originally conceived as part of a loop Interstate with a directional suffix, I-5W.[5]However, I-5W and most of the other Interstates around the country with directional suffixes were eventually renumbered or eliminated, exceptI-35EandI-35Win Texas and Minnesota.I-69segmentsI-69W,I-69C,andI-69Ein southern Texas have since been designated as well along with proposed suffixed segments for future extensions ofI-14andI-27to follow. The former route of I-5W now corresponds toI-580from I-5 south ofTracytoOakland,I-80from Oakland to Vacaville, and I-505 from Vacaville to I-5 near Dunnigan.
The northernmost section of I-505, between SR 16 in Madison and I-5 near Dunnigan, opened in August 1977.[6]
