Tennessee Department of Transportation maintenance crew began work Monday to repair a sinkhole discovered on State Route 66/Winfield Dunn Parkway south of Huffaker Road.  
     The sinkhole was discovered Monday morning in a northbound turn lane which would allow motorists to turn right onto Huffaker Road.
     TDOT geotechnical engineers believe there is a sinkhole under the pavement that has caused the cracking and depression on the surface.  The right hand lane is now also closed and will remain closed while crews dig up the pavement to reveal the size and source of the sinkhole.
      Motorists should be aware of the repair work and use caution while traveling through the emergency work zone.  The sink hole is not in the construction zone on State Route 66.
