Why Is It Called Century Boulevard? The Story Behind South Los Angeles’ “100th Street”

LOS ANGELES — Century Boulevard is one of the most recognizable east–west corridors in South Los Angeles, stretching from Watts to Los Angeles International Airport (LAX). But despite its grand-sounding name, the origin of “Century” is surprisingly simple—and rooted in math.
The Meaning Behind “Century”
Century Boulevard sits roughly 100 blocks south of downtown Los Angeles, where the city’s street numbering system begins at 1st Street and Main Street. Instead of naming the road “100th Street,” city planners opted for a more distinctive and memorable name: Century Boulevard.
In this case, “Century” literally means 100.
Part of Los Angeles’ Grid System
Los Angeles was designed using a grid-based street layout, especially in its expanding southern neighborhoods during the early 20th century. Streets were often named or numbered based on their distance from downtown.
Century Boulevard aligns with what would have been the 100th Street corridor—making it a key reference point in the city’s geography.
A Street That Evolved Over Time
Before it became Century Boulevard, portions of the roadway were known by other names, including Pine Avenue and San Antonio Street. As the region developed and expanded, these segments were unified under a single name in the 1920s.
This consolidation helped streamline navigation and supported growing transportation needs.
From Local Road to Global Gateway
The importance of Century Boulevard grew significantly with the rise of Los Angeles International Airport (LAX). Today, it serves as a major gateway for millions of travelers entering the city.
The road connects diverse communities—from historic neighborhoods in South Los Angeles to the bustling airport corridor—making it both a local lifeline and an international entry point.
More Than Just a Name
Century Boulevard reflects a broader pattern in Los Angeles street naming:
- Some streets honor historical figures
- Others reflect geography or culture
- And some, like Century, are rooted in the city’s structured grid system
It’s a reminder that even the most ordinary street names can reveal deeper stories about how a city was built.
The Bottom Line
Century Boulevard isn’t named after an event—it’s named for its location. Positioned at the 100th Street line, it represents both the logic of Los Angeles’ design and the growth of the city over time.
