Two lawsuits filed by six groups aim to halt the completion of the Oak Hill Parkway project, a proposed $550 million expansion of the “Y” just outside of Austin.
Initiated by water watchdog group Save Our Springs (SOS) Alliance, the first lawsuit, filed July 29, alleges expansion of the U.S. 290 and Texas 71 interchange could threaten local endangered salamander populations, including the Austin Blind Salamander and Barton Springs Salamander.
That first suit was filed against Texas Department of Transportation (TxDOT) and the U.S Fish and Wildlife Service. SOS is asking that the project come to a halt until TxDOT can comply with the Endangered Species Act, according to the suit.
