Sinkholes:  Facts and Photos

This giant sinkhole collapsed in Bowling Green, KY, just a few miles from the site of the proposed Kentucky TriModal Transpark. It is approximately 200 feet in diamater, and 35 feet deep. STOPTRANSPARK.ORG

To learn about sinkholes and the damage they can cause, visit the following Web sites. We think you'll agree that building an industrial park and airport in the Sinkhole Plain of Warren County, KY is a very bad idea.

When the sign says "stop," you'd better stop! Luckily, the driver of this pickup truck was not seriously hurt when the road collapsed beneath him.

The sinkhole ruptured water and sewer lines. Imagine what could happen if a sinkhole would damage pipelines carrying sewage or hazardous chemicals at the Transpark. Such collapses can sever sewage lines and storm drainage conduits, along with gas lines, fiber optic cables, and underground electric lines. All structures are vulnerable and subject to expensive repair.

The Dishman Lane sinkhole under repair

The $1 million repair of the Dishman Lane sinkhole collapse in Bowling Green, KY required removal of loose material down to bedrock. Note the disection of the rock above the cave by groundwater. The cave passage is 30 feet wide x 20 feet high, with a river in the bottom

Two power shovels load collapsed material into heavy dump trucks. The contractor's plan is to install 200 feet of 4-foot diameter pipe (shown in background) to carry the water, and fill in the hole with boulders and collapsed material. The relatively small pipe will only drain a fraction of the backed-up water during heavy rains. The excess water pressure could cause additional collapses.

This sinkhole in Logan County, KY is 70 feet deep. It opened in 1997 after heavy rains. The geology here is similar to the site chosen for the Kentucky TriModal Transpark.

A sinkhole caused this house to crack in Bullitt County, KY.

This sinkhole is in Pulaski County, KY, near where some politicians want to build the proposed Interstate 66, as well as a proposed bio-hazard laboratory. It only took about two days for the ground to sink approximately 30 feet. The entire sinkhole, which is not visible in this photograph, is wider than a Major League baseball diamond.
Sinkholes frequently develop at the Capital City Airport in Pennsylvania. This one was repaired in September, 2001, and then collapsed again after a heavy rain fell.

Unfortunately, some property owners use sinkholes as trash dumps. This one near Duncan Hines Highway and I-65 in Bowling Green, KY is filled with demolition debris. The weight of material and water seepage will eventually cause it to collapse. Sometimes dumps like this are permitted, but the record of dumping dangerous construction substances, such as glass fiber insulation, and the laxity of enforcement is a common occurence. Another demolition dump nearby, which closed in 1987, is contaminating the Barren River, costing taxpayers millions of dollars
