A neat find as construction crews work to widen Ranch to Market Road 620. They found a very large cave.
The cave was found just a few feet below the surface along 620, near Smyers Lane, just west of Round Rock.
The site is closed to the public. We're told it's about 100 feet long and 60 feet wide, with 20 foot ceilings.
The cave has the same types of formations of stalactites and stalagmites as other caves found in the area. It was discovered on June 13 as TXDOT was making way for piping to go into the ground to widen RM 620.
County officials tell us the project is now on hold until they can determine how they're going to complete construction around the cave.
"There are basically three options for a construction project which has the occurrence, which is common in Central Texas. One would be to create a bridge that goes over the feature. One would be to seal it and to fill it in or to reroute construction," Williamson County Public Affairs Manger Connie Watson said.
The county expects to have a plan by the end of the month.
