Here's a scan from a 1968 Houston Tourguide map published by Gulf Oil Company. This map clearly shows "Old Main Street Loop Rd" being truncated by the Astrodome sports complex. The rest of the road goes SW down to Main Street & Stella Link. This map even shows a few streets that are now completely gone without a trace that ran between "Old Main Street Loop Rd" and "Alt 90"; the streets of Ingleside, Clearview, & Hilcrest. A careful comparison of these three streets and current GoogleMap imagery appears to show no signs at all of these old streets existence. I wonder what or who used to live or exist on these old non-existent streets? I do also notice the old street of Fariss on this map going both east and west of Alt-90, where today it only runs east of Alt-90. Lastly, the "Old Main Street Loop Rd" did NOT run across the railroad tracks at this time and go any further. If it did run longer than the railroad tracks, like TexasFreeway.com indicates, it was before this 1968 map. Funny how AstroWorld is under construction on this map and today there's no hint it was even ever there.
