@citiesbydiana: Robert Moses and Gilmore D Clark discussing his construction projects in NYC and what he would do in Los Angeles (archival footage, 1959) 😼⛽🌆🗽#robertmoses #urbanism #satire #newyork #losangeles #parody In Los Angeles and much of Southern California, people commonly use "the" before the name of a highway, such as "the 405" or "the 101." This usage likely stems from a combination of regional linguistic habits and the specific nature of the highways in the area. In Southern California, highways are often referred to by their numerical designations, and adding "the" before the number helps clarify which highway is being discussed. It's a regional quirk that has become a standard part of local speech.
