A former Union officer from Ann Arbor, Michigan, William Andrew Slayton (1854–1935) was the stone contractor. Slayton lived in a stone house at 533 Barton Avenue, the house known for years by later inhabitants as the location of the "Little Art Shop". It is not known if he built this house, but similarly to Washington Roebling and the Brooklyn Bridge, he could overlook the project from his window. Many of the low stone walls in North Chattanooga are made up of the remnants of stones deemed too small for use in the piers. Subdivision plats in Chattanooga suggest that Slayton developed some areas to facilitate the hauling of materials from quarries in northeastern Alabama, and Slayton Street and Slayton Avenue are found near the current public library location on Broad Street.
