A Texas toll road with the nation's highest speed limit will get signs warning drivers about wildlife after at least three incidents of vehicles colliding with animals in the first few days of the new 85 mph zone. The private company that runs the 41-mile portion of Texas Highway 130 said Tuesday temporary electronic message boards were being used until permanent signs can be installed. According to SH 130 Concession Co. spokesman Chris Lippincott, the company decided to put up the signs based on early driving experiences on the north-south freeway designed as a bypass around Austin. The 85 mph portion opened last week. Authorities say there have been at least three collisions, including two with wild hogs. No one in the vehicles were hurt.
