德克萨斯州州际公路均为德克萨斯州所有，并由其维护。[1]德克萨斯州交通部（缩写：TxDOT）负责位于德克萨斯州境内州际公路的日常维护和运营工作。德克萨斯州州际公路全长3,239.7英里（5,213.8公里），共有10条主干道，六条辅助线路，以及分为东西两线、分别联通达拉斯和沃斯堡的35號州際公路（I-35）。位于德州境内的州际公路路段中，最长的为10號州際公路（I-10），长878.6英里（1,414.0公里）；最短的为110號州際公路，长0.9英里（1.4公里）。

德克萨斯州的州际高速公路系统建设早于这些公路正式被冠以“州际高速公路”的名号。长50-英里（80-公里）、连接Galveston和Houston的45號州際公路于1951年开通，8年后它才被冠以I-45之名。它也是德州的第一条城市快速公路。1962年，43英里（69公里）长的35號州際公路比爾縣段开通，这是首个位于大都市区域、联通县级公路的州际公路。[2]位于圣安东尼奥以西的10號州際公路路段由于过大的空间和附近缺乏劳工，工期严重延误。该路段建设工程跨越20世纪70、80年代，共最终于90年代完工。而圣安东尼奥以东的路段早在1972年就已完工，早了20年。[3]1992年，随着长6-英里（10-公里）的27號州際公路路段开通，德克萨斯州州际公路系统正式完工。[4]

目前提议中的扩建工程包括69號州際公路南延，从目前在印地安那州的终点一路贯穿德州，直达美墨边界。[5]如果该计划顺利完工，69号洲际公路将会延长约650英里（1,050公里）。[6]该工程首段长6.2-英里（10.0-公里），已于2011年获得批准，标志牌于2011年12月6日公布。
