 A second concrete span for Benning Bridge was constructed in 1961; the old span now carried eastbound traffic, while the new span carried only westbound traffic.In 1961, the NCPPC proposed filling in of Kingman Lake (about 50 to 60 percent of the lake's total area) and relocating some of the riprap walls to make Islands 3 and 4 part of the mainland and add an additional to Langston Golf Course.This plan was never acted on, and a year later the city proposed turning Kingman Island into a landfill.
