Scajaquada Superstructure - Buffalo NY

In 2005, The L.C. Whitford Company won an 18-million dollar contract from the New York State Department of Transportation to lead the Scajaquada Rejuvenation Project in downtown Buffalo. The Scajaquada Expressway (NYS Route 198) is one of the most vital arteries in the city, carrying up to 59,000 vehicles daily. This project focused on ensuring that the Scajaquada remains in good condition, and involved the repair and refurbishment of seven bridges at the interchange of the Scajaquada and the NYS Thruway (I-90).

The project included concrete repairs on the substructure, steel repairs and replacements of diaphragms and coverplates, the replacement of over 1,200 bearing-and-pedestal sets, and joint seal replacement. In addition, all steel was blast cleaned and repainted, and all concrete surfaces were protected with a coat of epoxy-based sealant. LCW employed over 90 workers for the project, which was completed in the summer of 2007.

One aspect of this project was especially noteworthy. According to the DOT, this was the first large-volume use of self-compacting concrete in the region, which shows the major changes that have occurred in concrete substructure repair over the past 25 years, and demonstrates the ever-innovative nature of The L.C. Whitford Company.
