(HOUSTON CHRONICLE) SAN ANTONIO – An endangered species of spider not seen in more than three decades unexpectedly appeared in northwest San Antonio two weeks ago, showing up in the middle of a $15.1 million highway underpass project.

The highway project is now on hold indefinitely.

A biologist discovered the eyeless spider, called the Braken Bat Cave meshweaver, after rain exposed a 6-foot-deep natural hole in a highway median at Texas 151 and Loop 1604.
