Post 1964 Signage History
Route 305 was never legislatively defined. However, there is a portion of
route that is known to AASHTO as I-305 for funding purposes. This segment,
the Route I-80/US50 interchange in West Sacramento to the Route 99/US50
interchange was originally part of I-80. It was redesignated as chargeable
I-305 in May 1980 (and that designation remains on the books at AASHTO).
in 1980, it was reassigned to US 50. It is currently signed as US50/Business Route 80
the jct with Route 99/US50/Business Route 80 on east side of Sacramento to the jct.
Note: Although I-305 is signed as US 50, itis still on the books as
Federal-Aid Interstate 305. The FHWA log shows it as 8 miles.
