Old US 70 across the Blue River, Bryan Co.

Built in 1921 by the General Construction Co., St. Louis Mo., this 96 foot modified Pratt stands east of Durant across the Blue River.

Above, an overview of the bridge. This span is a state standard design and was built all over Oklahoma in lengths up to 120 feet. Unlike many, this one has a plain A-frame style portal. This bridge also features a steel stringer  and concrete deck approach at each end.
