Navarro Motel On Old Main Street Rd.

[Highrise Tower]

I found an usual motel this week. I wanted to ask HAIF if anyone knew more about it. 

Mainly, the address.  I'm unsure if the old hotel/motel is located on South Main Street, or Old Main Street Road (in this instance, South Old Main Street Road) I guess we can figure this out by the date? This was in 1957, so I believe OMSR was still an active road. If you notice, all the other motels are listed as "S. Main" whereas the last motel, Navarro Motel, is worded differently. Makes me think it's not the same as the others, not on South Main Street. Or perhaps, the writer/journalist/reporter did not know the exact location?

Any photos of this historic motel? Any more details?
