The footers are 4ft wide, total wall length is 26' the the bearing stem wall is 8' long-16" wide, the wing walls are 8" wide. And the stem wall height is 6.5' How much Concrete have we placed? Closest guess gets a prize! #nationalpark #cumberland #Virginia #tennessee #kentucky #tristate #bridges #naturalresources #construction #concrete #formwork #hardwork #dirty #water #waterfall #history
