 For some reason, the new railroad company decided to forsake the old, tall granite piers in favor of new, shorter concrete piers.This may have been because of the age of the granite piers or perhaps the concrete was thought to be stronger.An interesting historical note about these newer stone piers is that some have fallen over in the years since the bridge was taken down in 1970 while all of the original 1838 brick piers still stand tall.
