The service road probably came with the "I-35" name from the basemap. That's totally wrong. IME, service roads always have some signed name, even if it's "I-35 Service Rd" (don't abbreviate Svc, as you said). Other times, it will be "Frontage Rd", or it may even be "Juniper St" or some other name unrelated to the freeway it fronts.
Here, we have a lot of "N I-10 Service Rd W" with the different non-sensical directions and cardinals. The signs all say "Svc" but the pronunciation is so bad, I converted them all to "Service" a year ago.
