While on a recent Bay Area trip I primarily focused on routes I hadn't previously taken or didn't really research much in the past. One such route was Interstate 505 which as originally conceived was meant to be part of Interstate 5W. I-505 is a fairly unassuming 33 mile three digit Interstate connecting I-80 near Vacaville in Solano County north to I-5 near Dunnigan in Yolo County. I-505's most significant claim to fame was that it was approved to be part of I-5W. The entire route of I-505W was part of Legislative Route Number 90 before the 1964 State Highway renumbering. LRN 90 was approved by the State Legislature in 1933 according to CAhighways.org. CAhighways.org on LRN 90 LRN 90 was not a signed highway before the 1964 State Highway renumbering. The alignment of LRN 90 was far from the straight north/south shot that I-505 is today. The route of LRN 90 between US 40 near Vacaville and US 99W near Zamora/Dunnigan can be seen on the 1938...
Because every road has a story.
