Around 1870, a flourmill was added and Golden engaged Charles Temple and his son John as millers. By 1880, another of Charles Temple’s sons, Samuel, was also working at the flourmill, which ground wheat flour, feed and Indian cornmeal on its three sets of millstones. The milling operations were seasonal, small-scale and short-lived; neither lumber nor grain processing continued beyond the 1880s. The reasons for the mills’ demise remain murky. Was it the economy? Did Stony Brook flood and damage the workings?

Mill customers wanted access to a mill from both sides of a creek. When the first bridge carrying Province Line Road over Stony Brook was built is also unknown. It may have been shortly after 1864 when local residents petitioned Mercer County for a bridge. A bridge appears to be in place in 1875, as seen on a map of that year. In 1882, the abutments were repaired and the timber deck was replaced. The present span, a Warren pony truss constructed by the Berlin Construction Company of Berlin, Connecticut, and installed in 1903 on the old stone piers and abutments, is the longest and one of the best preserved of its type in the county.
