In January 1979, an in-depth investigation of the unstable bridge-approach embankment, Figure 1, on US 68 over the Licking River in the north central portion of Nicholas County (MP 91-68-B0027) was begun by the Division of Research. This investigation was a continuation of a project initiated by the Division of Materials in 1967. This site is approximately 0.3 miles (0.5 km) north of Stony Creek Road and approximately 7.5 miles (12.0 km) north of Carlisle and 0.8 miles (1.3 km) southwest of Blue Licks Battlefield State Park. The bridge is a three-span, continuous, welded plate girder structure with span lengths of 160, 2004 and 160 feet (48.8, 61.0, and 48.8 m) at a 0 degree skew. The bridge is aligned at north 47 degrees east. The pier foundations are spread footings on rock; the abutments utilize 12 point-bearing (53 steel-type) piles. The roadway emerges from a cut of approximately 20 to 40 feet (6.1 to 12.2 m} near Stations 217 + 50 and 221 + 00 on the right and left, respectively. The nearby bridge approach embankment rests partly on a bench of limestone and partly on an alluvium river bank. Maximum height of the embankment is about 100 feet (30.5 m).
