Earlier in the summer, we re-visited the reasoning behind why Washington, DC’s street naming system. From A Street to Verbena Street and from Half to Sixty-Third, DC’s lettered and numbered streets make it difficult to get lost with their logical progressions.

But DC’s transverse diagonal avenues confound everyone from tourists to suburban motorists. Not only do they break all the grid rules, they even manage to break up the grid itself in many places, like H Street, NW at New York Avenue. And to make matters worse, they often skip across parks, rivers, even entire neighborhoods, before starting up again, sometimes even on a different heading.

Locals have mostly figured out where the avenues are, at least the major ones. Maryland residents use many of these broad streets as their connections to downtown, but a short street like North Dakota Avenue goes unnoticed by almost everyone outside the immediate neighborhood.

In fact, when the city was first established, the organized naming system extended to state-named avenues as well. It was not quite as intuitive as the numbered and lettered streets, but with only nineteen avenues, it was still easy to understand.

As I noted before, the plan of the city was meant to reflect the structure of the government. For that reason, the city’s quadrants are centered on the Capitol Rotunda. The state-named avenues are no exception. Being the major streets of the city, L’Enfant’s plan placed many of them so that they emanated from certain points. In this regard, they provided long unobstructed views toward the icons of our nascent government.

From the Capitol, North Capitol Street stretches northward, followed in a clockwise direction by Delaware Avenue, Maryland Avenue, East Capitol Street, Pennsylvania Avenue, New Jersey Avenue, South Capitol Street, Delaware Avenue, the Mall, Pennsylvania Avenue, and New Jersey Avenue.

From the White House, Sixteenth Street forms the major axis. In fact, Thomas Jefferson intended it to become the Prime Meridian, which is where Meridian Hill Park gets its name. Moving clockwise, one encounters Vermont Avenue, New York Avenue, Pennsylvania Avenue, New York Avenue, Pennsylvania Avenue, and Connecticut Avenue.

Today, some avenues are more important than others. This is due, in large part, to where it is they connect to, not any particular naming convention.

The grand avenue, home to everything from Inaugural Parades to festivals of all sorts, is Pennsylvania Avenue. Connecting the Legislative and Executive branches, it was always meant to be the heart of Washington. In the southeast, it continues as a major roadway toward central Prince George’s County, Maryland.

Similarly, Connecticut, Georgia, and New York all are major thoroughfares to outlying parts of the region. Another important street is Wisconsin Avenue, running from M Street in Georgetown to the Beltway north of Bethesda; it was an important road long before the name was applied. As late as 1903, it was still called the Georgetown and Rockville Pike. This historic name is the basis for two streets in suburban Montgomery County: Old Georgetown Road and Rockville Pike, the straightened version.

Some feel that certain states got short shrift. Tiny Delaware has a fractured, relatively unimportant street. However, the main reason that it is less important today is because of its strategic importance as a transportation corridor. To the north, Amtrak, MARC, and Metro’s Red Line trains use Delaware Avenue to enter the L’Enfant City. Similarly, Maryland and Virginia Avenues in Southwest and Southeast now have above-grade railway embankments carrying trains along streets intended to be grand public avenues.

But street-naming doesn’t have anything to do with importance to the Revolution or the prestige of any one state, at least not directly. State names were assigned to avenues based on their geographic location within the United States.

For that reason, one found Georgia Avenue in the southernmost portion of the city. Running from what is now Fort McNair across the southern side of Capitol Hill, we know it today as Potomac Avenue. Near the northern edge of the city, the avenue named after the then-northernmost state, New Hampshire, passed through Washington and Dupont Circles, just as it does today.

Vermont joined the union in 1791 as the fourteenth state, while Kentucky joined in 1792. It was during these years that Washington was being laid out. For that reason, they both received places within the system. Tennessee gained statehood in 1796, and its avenue became the first glaring error. After all, Tennessee forms the southern boundary of Kentucky, yet Kentucky Avenue lies entirely south of Tennessee Avenue.

By the time Congress first met here in 1800, there were three diagonal avenues left to be named. Ohio and Indiana fit into the system well enough, but Louisiana was sorely out of place.

With the first nineteen states represented in the city, Washington ran out of avenues. Maps from the 1800s available on the Library of Congress’ website show that Maine and Missouri had short avenues within the bounds of the Mall, but it is unclear exactly how all the new states were represented as they came on board.

In 1890, Boundary Street was renamed after the twenty-seventh state, Florida. Despite being farther south than any other state (it would remain so until 1959), it got the street forming the northern boundary of the city.

Yet by the time the twentieth century got going, Washington was expanding into the hills and dales above the Fall Line. As the street grid expanded, new avenues were added, and old ones obliterated. Around 1914, the citizens of Brightwood managed to get Brightwood Avenue renamed after Georgia. They had hoped to curry favor with senator Augustus Bacon, but he promptly died, and never had a chance to affect the fortunes of these suburban pioneers. The construction of the Federal Triangle complex in the 1930s eliminated Ohio’s avenue and shortened what had been Louisiana Avenue. Louisiana’s name itself had moved a few blocks east to a new street constructed as part of the changes brought by Union Station and Columbus Circle in 1907.

Today, one can still see some geographic order to the state-named avenues. However, much of that is due to the age of certain regions. After all, New England hasn’t had a new state since number twenty-three, Maine, joined in 1820. For the most part, states on the East Coast can be found downtown. Alaska Avenue is the northernmost avenue (in its entirety). Mississippi, which is at least in the south, is the southernmost state-named avenue. But the similarities largely end there.
