The first part of the Boulevard of the Allies, named in honor of the Allies of World War I, was dedicated on August 8, 1921. It would be another two years before the entire highway was opened to traffic. As an experiment, one of the first interconnected traffic signal systems was installed on the boulevard in November of 1923. Before its completion, its cost was reported as $1.6 million per mile, the most expensive road in the world at the time.

According to newspaper reports from 1921, there had been plans to places statues and memorials along the Boulevard's route, but those never came to be.
