In May 1927, Kendall presented a revised design for the B Street approach to the Lincoln Memorial traffic circle. The NCPC, concerned with the impending construction of Federal Triangle, worried that a traffic circle would not only fail to accommodate the expected increase in traffic volume but also impair the dignity of the memorial as large numbers of fast-moving automobiles whizzed around it. CFA members did not agree. For example, CFA member James Leal Greenleaf argued that the traffic issue was a red herring; future new bridges over the Potomac would completely alleviate all traffic issues within 50 years, he said.
