Texas 45, proposed as a major east-west artery for southern Williamson County, cleared a significant hurdle Thursday when it received final environmental clearance. Officials say the news is crucial in the quest to provide congestion relief for motorists in northern Travis and southern Williamson counties. However, the Texas Turnpike Authority, a division of the Texas Department of Transportation, still faces two major issues. The state is conducting traffic and revenue studies to determine whether to make Texas 45 a toll road, Dillard said. The decision will be made by the end of the year.
