From the Lawrence Daily Journal-World for Sept. 7, 1972:

At a recent Lawrence City Commission meeting, a request for a temporary crossing guard and an eventual traffic signal at a Lawrence intersection was deferred for study. Bill Womack, maintenance and operations director for U.S.D. 497, had told the commission that the intersection of 19th and Louisiana was congested, especially in early morning, and that children heading toward nearby Centennial School were endangered. Commissioners responded that the installation of a traffic signal at that corner was already under study; they were attempting to calculate the difference in cost between buying new signals and bringing old signals up to current code before installation.
