I-69 restricted in Hopkins County by shifting ground beneath roadway

One lane of I-69 in Hopkins County continues to be closed by shifting ground conditions beneath the roadway.

The Kentucky Transportation Cabinet is continuing its investigation into ground subsidence along the northbound lanes of Interstate 69 near Mortons Gap. The slow lane has remained closed since last Friday, due to damage caused by shifting conditions beneath the roadway.

The issue first appeared earlier this month after several rounds of heavy rainfall, when a section of the slow lane and shoulder began to slide, creating cracks in the pavement. KYTC crews performed initial repairs, but the condition continued to worsen.

Last week, engineers excavated a large section of embankment and drilled core samples, reaching depths of 31 feet. However, the source of the subsidence has not yet been identified.

Engineers will continue to drill multiple locations at greater depths until the void or cause is located. Only after the source is confirmed can a permanent repair plan be developed.

Historical records indicate underground coal mining occurred in this area, although detailed records of mine location and depth are unavailable. 

KYTC is coordinating closely with the Kentucky Division of Abandoned Mine Lands and the Kentucky Energy and Environment Cabinet to assist in the investigation.
