Route history

The routing between Madisonville and Navasota was originally set before the state's highway system was started. By 1919, a rail route between the cities existed, run by the Great Northern Railroad. By 1922, a basic highway had been built between the cities, which was designated as State Highway 32A, which branched off the main State Highway 32 in Madisonville. By 1926, the state roads department had begun to get rid of most suffixed spur routes, so this route was again renumbered as State Highway 90. The route remained a minimally serviced dirt road until the early 1930s, when paving occurred. Numerous reroutings occurred during the next 70 years, including being rerouted away from the town of Washington and the eventual transferral of the section between Brenham and Navasota to State Highway 105 in 1973.
