There have been some changes to CA 58 between I-5 and CA 99. Caltrans has relinquished the former alignment of CA 58 along Blue Star Memorial Highway and Rosedale Highway between I-5 and Mohawk Street and moved the signed route to Stockdale Highway, which lines up with Westside Parkway. Per the postmile lookup tool, SR 58 now follows Stockdale Highway. Apart from I-5 Exit 253, where 58 is not signed from I-5, the new route is very well-signed, including with signs along Mohawk Street connecting Westside Parkway to Rosedale Highway. EB traffic along CA 58 is directed to use I-5 SB. GSV shows that signs along the old route have been removed.
As of today, the signed route is as follows:
- West of I-5: No change
- I-5 concurrency between Stockdale Highway (Exit 253) and Exit 257, reinforced by signs at each end of concurrency telling CA 58 traffic to use I-5
- Stockdale Highway between I-5 and Westside Parkway
- Westside Parkway west of Mohawk Street
- Mohawk Street between Westside Parkway and Rosedale Highway
- Rosedale Highway between Mohawk Street and CA 99
I propose that CA 58 be moved onto the above route. Basically, this would involve routing CA58 onto what is now CA58Wes and WesPkwy west of Mohawk Street, with connecting segments along I-5 and Mohawk Street. Westside Parkway east of Mohawk Street is unnumbered at this time, but will become numbered when the CA 99 interchange is complete. I drove CA 58 today and can confirm that the above is signed in the field.
