After years of delays, San Antonio's government finally came up with a hazmat routing plan. But any of six suburban cities where the proposed routes pass through could veto the plan.

The plan was finally developed after 20 years of delays after a tractor-trailer wreck spilled acid in downtown San Antonio in December.
The plan would van hazardous materials from the elevated highways downtown. It would designate highways such as Texas 16 (Bandera Road) and Loop 410 as routes for trucks carrying hazardous cargo through Bexar County. Some residents of Leon Valley and Helotes, two suburbs on Bandera Road, want that route removed from the hazmat designation, according to the San Antonio Express-News.
Other cities with veto power are Castle Hills, Elmendorf, Live Oak and Selma. Several members of the Castle Hills City Council have said they may oppose the plan.
If any of these six suburbs fails to pass a resolution of support, the San Antonio hazmat plan will die. If that happens, the state Department of Transportation will step in and consider a state-mandated plan.
