In 1929, the Bismarck CIty Commission began to take control of parking by instituting a two-hour parking limit in the business section between 7am and 6pm. They ordered 65 signs to post around the city for that purpose, and it went into effect the first of May of 1930. Commissioners also decided to paint the parking lines on the sidewalks in yellow instead of the red that had been used, so that they could be seen better at night.
