Project Description:

This project represents the experience of David C. Depp, P.E., while employed by American Consulting Engineers.

This project, located in Owensboro, Kentucky, involved widening Carter Road from 2-lanes with minimal shoulders to 5-lanes with full-width shoulders, and included the replacement of the existing bridge over US 60 Bypass, a 4-lane freeway with depressed median. The new widened bridge was constructed using staged construction to maintain traffic on Carter Road. The new bridge is 81.3 feet wide and 253.3 feet long, including 4-spans with lengths of 45.5-82.0-82.0-40.5 feet, and is framed using Type 4 PPC I-beams with composite concrete deck. The spans were arranged to provide a 30 foot clear zone along the outside shoulders of the US 60 Bypass, and avoid the need for guardrail. The substructures consist of integral end bents and multi-column piers, both founded on prestressed concrete friction piles. Construction was completed in 1998 at an estimated cost of $832,000 ($40/sf).
