WILLIAMSON COUNTY, Texas -- Construction is underway to fill the Brushy Creek Cave that collapsed after a waterline leak in February.

It took months to figure out how to fix the problem, but ultimately Williamson County officials decided to fill it with concrete.

The cover of the cave was removed Monday morning and this week crews will begin to excavate the material that fell in during the collapse. After it is all removed, the environmental team will come back out to examine the cave again. They are looking toward Ephraim Road to examine a void that was found during drilling. 

If the void is connected to the cave on Cambria Drive, it will also need to be filled in.

"If everything goes according to the regular schedule, they will begin the process of filling in the cave and that will be done 18 inches at a time. They will have to set the forms and set that in to build it up until it reaches the top of the cave, where they can start putting in the utilities, repairing the utilities and then putting the road back together,” said Connie Odom with Williamson County Public Affairs.

The county will not be filling in the portions of the cave that are underneath at least two nearby homes. The public is asked to stay clear of this area. There will be 24 hour security to make sure that residents are safe and to keep trespassers out.

The county expects to finish construction in October.
