The Kentucky Transportation Cabinet conducted a large-scale zone maintenance painting operation on 13 elevated steel bridges along the I-64 Riverside Parkway in Louisville, KY in 2007. That work included abrasive blast-cleaning and painting of steel underlying open deck joints on 3.2 miles of steel structures. The painting was performed by spray application of one coat of a calcium sulfonate alkyd coating. The painting covered an area of 237,060 ft2 of steel cleaned and painted at a unit cost of $15.82/ft2.
The project incorporated a high level of containment as the existing coating possessed lead-based paints and the project was located in a densely populated area. The project was successfully completed in 4 months. Follow-on inspections conducted at 2 and 14 months respectively indicated that almost all of the zone painting was in good condition and performing satisfactorily.
