From the Lawrence Daily Journal-World for Aug. 9, 1972:

A front-page photo showed the progress being made on the downtown reconstruction project. Specifically, the new curb design was explained to the reading public. “Sawtooths, Scallops, Zig-Zags — Whatever you call them, they are solidifying on the east side in the 900 block of Massachusetts Street as part of the downtown improvement project. The sidewalk is to be extended to the inside point of the sawtooth, and trees and new lighting will alternate in the triangles. At all corners the sidewalk has been expanded and the curbs have been poured around the future mid-block crossings. The expanded corners will leave a 38 foot wide Massachusetts Street, which will allow two lanes of traffic. The changes will make downtown safer for pedestrians, according to Don Schaake, director of the Neighborhood Development Program.”
