<div dir="ltr">This realty company advertisement from 1924 is interesting. It shows scores of people walking through the Liberty Tunnels using four sidewalks. In the late 1920s, early 1930s auto traffic had to be restricted by limiting the number of vehicles in the tunnels at any given time. This was done because many drivers were actually becoming Carbon Monoxide victims during peak traffic periods when traffic would be standing in the tunnels. This also brought about the installation of a ventilation system to keep the air somewhat clean inside the tubes. I could imagine that the majority of those pedestrians, walking through the tubes in the advertisement, would never make out the other end do to Carbon Monoxide gas.<br>
