On Norfolk Southern Railway's CNO & TP Lake Division near Crescent Springs, Kentucky, there was a progressive slope failure that accelerated with spring rains and thawing to the point where there was concern for the stability of the rail line. Fenton was contracted to perform emergency remediation work to stabilize the slope for 500 linear ft. Fenton installed 70 drilled shafts as soldier piles then drove sheet piles behind the piles for lagging. Nicholson then installed 26, 88-kip tieback anchors bonded in rock. The 70-foot-long anchors were installed using duplex drilling techniques with an excavator mounted TEI drill mast. The excavator was able to drill from the top of the slope reaching over to install the anchors. Anchors were drilled through ballast, clay, and into weathered shale and limestone. After the anchors were installed, Fenton installed walers to connect the anchors to the solider piles. This provided the stabilization required to stop the progressive slope failure.
