1938 Texas road maps
A highway line did not promise pavement in 1938. These Humble Oil sheets distinguish paved roads from gravel, unimproved routes and dirt roads. Start with a region, then check the legend before tracing your route.
Follow US 66 across the Panhandle or look for the coastal crossings in South Texas. These Gulf Oil sheets show the roads before the interstate network; the legend helps distinguish a divided highway from the freeway a modern reader might expect.
The interstate network was beginning to appear, but a heavy line on this map still needs a closer look. These Humble Oil sheets show central and western Texas, with a legend for reading the highway symbols.
The routes are familiar; the gaps may not be. These Enco sheets cover the Houston–Dallas–San Antonio region and Northeast Texas while interstate construction was underway. Compare the road symbols with the legend to follow the work.
Seven sheets give this edition the broadest coverage in this collection. Trace the interstate corridors from the major cities to the Panhandle and Far West Texas, then compare them with earlier or later editions.
A single year can be worth a second look. Compare these Texaco sheets with the 1966 edition, especially along I-10 west of Houston and the highways south of San Antonio. The original commentary points out changes to follow.
Look along I-45, I-10 and the routes across South Texas and the Panhandle. These four Texaco sheets capture a highway network still taking shape, with the original commentary beside each regional view.
The archive ends this sequence with South Texas and West Central Texas. These sheets from the Official Texas Travel Map are useful for following I-35, I-37, I-20 and I-10, alongside the original notes about unfinished stretches.

Due to high detail, maps have very large digital images.
High resolution: crystal clear
Medium resolution: adequate for viewing, but some detail can't be seen
Low resolution: barely legible, only good for getting the basic idea
