An 80-plus-year-old bridge over Muncy Creek, at the junction of Routes 405 and 442, is being demolished, and construction workers have been asked to be on the lookout for remnants of a Colonial-era grist mill.

Among the artifacts being sought are the original burr stones from the mill, which was a log structure and the first mill of its kind in the county.

The stones, which would date from the 1700s, and bricks from a five-story mill built at the same site in the 1800s, were used as fill when the current bridge was built in the 1920s to replace a wooden covered bridge.

The original mill was constructed in 1772 at the approach to the creek about where a convenience store-gas station complex now is located.

Any artifacts uncovered during demolition will be turned over to Oliver Sones, who has developed a passion for tracking down the area
