February 10, 1937, the southern section of SH 16 was rerouted northwest and northeast to Fredericksburg, replacing part of SH 81. On September 26, 1939, the section from Brady to Santa Anna was promptly reassigned to U.S. Highway 183. The section from San Antonio to Corpus Christi, which was cosigned with US 181, was cancelled. The section from Corpus Christi to Robstown was transferred to rerouted SH 44, south of Robstown to rerouted SH 96 (now US 77), and from there to Falfurrias became an extension of SH 285. The section from Sagerton to the Oklahoma State line was renumbered as SH 283. The sections cosigned with other state highways had their co-designation of SH 16 removed. SH 16 was rerouted north to south of Graham, replacing SH 81 and part of SH 120. SH 16 Spur was renumbered Spur 72. On August 31, 1965, the road was significantly extended via its current routing to Zapata, replacing State Highway 346 from San Antonio to Jourdanton, and also replaced portions of SH 173 and FM 496. On November 16, 1965, it was rerouted over Interstate 410 in San Antonio. On January 31, 1969, SH 16 was extended north to US 281, replacing portions of SH 254 and FM 61. The section of SH 16 from Loop 1604 to Eckhert Road (former FM 1517) was proposed for decommissioning in 2014 as part of TxDOT's San Antonio turnback proposal, which would have turned back over 129 miles of roads to the city of San Antonio. SH 16 would have been rerouted over Loop 1604, and Spur 421 and Spur 422 would have been extended over old SH 16. However, the city rejected the proposal. Future The section of SH 16 between Loop 1604 and Triana Parkway in Helotes is in the process of being upgraded into a superstreet. The main focus of the project includes reconstructing the intersections at Loop 1604 and FM 1560 / Circle A Trail. Construction at the Loop 1604 intersection is projected to be finished sometime in 2019.
