In 1928, the Cotton Belt undertook the St. Francis Basin Project, which was an effort to buy up six small railroads (including the BL & AS) on order to capture the promising business in Southeast Missouri and Northeast Arkansas. Another 30 miles of new lines was required to linke to Memphis, Tennessee.
