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.

🎥 The Knowledge – Episode: Garrett Morgan 

“The man who gave us stoplights also saved lives underground.”

Before Garrett Morgan became known for inventing the three-position traffic signal, he was already changing the world—one breath at a time.

In 1912, Morgan designed a safety hood to protect firefighters and miners from the deadly smoke and toxic fumes they faced on the job. This early version of the gas mask featured breathing tubes and a wet sponge to filter air—simple, yet revolutionary.

But the true test came in 1916, when a natural gas explosion rocked a tunnel under Lake Erie in Cleveland. With little hesitation, Morgan donned his invention and entered the chaos. He saved multiple workers trapped beneath the earth—risking his own life to prove his device could do what others hadn’t even imagined.

Despite his heroism, headlines of the day often left out his name. Why? Because Garrett Morgan was Black. His contributions were buried in the shadows of racial prejudice, even as his inventions were saving lives and modernizing cities.

Today, we’re changing that narrative.

Garrett Morgan didn’t just invent the gas mask—he proved it worked. And his legacy deserves to breathe.

Phoenix is the fifth-largest city in the United States, yet its skyline doesn’t resemble other major metros like Los Angeles, Chicago, or Dallas. Despite rapid population and economic growth, downtown Phoenix has long lacked supertall skyscrapers — and until recently, didn’t even have a building tall enough to qualify as a true “skyscraper” under standard definitions.  

The Basics: Phoenix’s Height Reality

The tallest structure in Phoenix for decades has been Chase Tower, rising to about 483 feet. Under the Council on Tall Buildings and Urban Habitat definition, a skyscraper reaches at least 492 feet — which means Phoenix has technically lacked one — despite its size and population.  

A new project, the Astra Tower, is planned to rise around 540+ feet when it breaks ground, potentially giving Phoenix its first true skyscraper.  

Airport Proximity: The FAA’s Height Grid

FAA Obstacle Evaluation & Downtown Limits

Phoenix’s skyline constraints are rooted in aviation safety.

📍 Phoenix Sky Harbor International Airport sits just a few miles from downtown.

• The Federal Aviation Administration (FAA) regulates building heights near airports so they don’t obstruct flight paths, require planes to alter approaches, or interfere with climb-out safety.
• In Phoenix, this results in a layered set of height limits that vary by location and elevation above sea level — often measured in feet above mean sea level (MSL) rather than simply building height from ground.  

The city’s zoning code divides downtown into multiple contour zones with distinct maximum elevation values (e.g., 1,275 ft, 1,525 ft, 1,700 ft MSL), each tied to how close it sits under airport flight paths.  

That means in some blocks you can’t build above a specific elevation even if ground levels are lower — a regulatory “roof” that varies across downtown.

City zoning also explicitly states that no building can exceed the FAA’s airport height limits, even if other bonuses or zoning allowances exist.  

Phoenix vs. Los Angeles: A Quick Comparison

Los Angeles: Higher Limits, Different Constraints

Cities like Los Angeles also have nearby airports (e.g., Los Angeles International Airport), but their key business districts aren’t directly under major flight corridors.

LA’s downtown has:

• Taller office and residential towers
• A financial core with dense development
• Fewer FAA-driven overlays because the flight paths stretch past the downtown edge

Los Angeles’s tallest buildings — including Wilshire Grand Center (~1,100 ft) and U.S. Bank Tower (~1,018 ft) — were built where FAA restrictions don’t force low ceilings. FAA evaluations were conducted but didn’t cut as deeply into downtown zoning compared to Phoenix.

Phoenix, by contrast, sits right under approach and departure corridors — leading to consistent FAA involvement in almost every proposed mid- or high-rise downtown.

Economic and Planning Philosophies

Beyond FAA rules:

• Phoenix developed in the automobile era, with vast inexpensive land encouraging horizontal growth.  
• Los Angeles grew earlier with heavier investment in centralized neighborhoods and higher density.
• Phoenix’s village plan long encouraged multiple smaller hubs instead of concentrating all growth in one downtown core.  

These historical differences mean Phoenix didn’t have the same economic “pressure” to build up — even with zoning that allows significant height if FAA permits are met.

What This Means for Phoenix’s Future

Phoenix still has room to grow vertically — but:

• FAA height contours will remain the ceiling unless flight paths change
• Developers must secure determinations of no hazard from the FAA before going taller
• New projects like Astra show demand for taller buildings is rising

As Phoenix’s urban core densifies and land becomes scarcer, its skyline may yet reach higher — but always within the invisible grid drawn by aviation safety.
