Is there a 90 mph speed limit in Texas?

Excuse me, could you please clarify something for me? I'm wondering if there's a specific speed limit of 90 miles per hour that applies in the state of Texas. Is there a particular highway or section of road where this speed limit is enforced, or is it a general rule that applies across the entire state? I'm interested in knowing the exact details, as I'm planning a road trip through Texas and want to ensure I'm adhering to all the local traffic regulations. Thank you for your help.
