TY, INDIANA
New US 231 between I-64 and the Ohio River in Spencer
County, Indiana. Beginning at SR 66 (Ohio River)
northbound 4.8 miles ending at a point 1.15 miles south
of SR 70.This project involved the construction of a new
dual-lane, partial access control highway that replaced a
two-lane narrow existing highway. Construction had to be
phased on the southbound then northbound sides to
maintain existing vehicle traffic and rail traffic into an
adjacent power plant.
Pavement design is 14.75" full depth HMA placed on a
line stabilized earth sub grade. The full depth pavement
design demonstrates the quality, appearance, and
rideability that can be achieved with HMA.
