“The Main Street of America”
In the 1920s, America became an automobile nation. At the start of the decade, there were 8 million cars on the road, but roughly 32,000 of the nation's 2.5 million miles of rural roads were paved, making transcontinental travel prohibitively slow. By the end of the 1920s, Americans owned 23 million cars, with many driving Henry Ford's affordable Model T.

More cars meant more demand for paved roads. In 1921, Congress passed the Federal Aid Highway Act, which called for a network of roads covering the entire country. A few years later, plans for interstate routes were approved for all 48 states. Route 66 stretched more than 2,400 miles from Chicago to Santa Monica, California. Cy Avery, the Oklahoma highway commissioner known as the "Father of Route 66," dubbed it "The Main Street of America." This route was considered the primary path between the Great Lakes and the Pacific Coast.

Route 66 was officially established in 1926. The Illinois stretch of Route 66 began as a two-lane road known as SB14, which followed the route of the old Pontiac Trail from Chicago to St. Louis. At first, SB14 began in Cicero, but its designation as Route 66 increased traffic. To accommodate this, the starting point was moved to Michigan Avenue and Jackson Boulevard in Chicago.

Ogden Avenue has traditionally been a major transportation route into and out of Chicago.

This street parallels both the south branch of the Chicago River, which was once the main waterway toward the Mississippi, and the Chicago, Burlington & Quincy railroad tracks. The Route 66 era was the heyday of Ogden Avenue and the neighborhoods it runs through. Route 66 was and still is an emblem of the nation's car culture. From the 1920s through the 1950s, dozens of repair garages, tire suppliers, and automobile dealers set up shop along the street.

The development of the interstate highway system, the result of a bill signed by President Dwight D. Eisenhower, led to the decommissioning of Route 66 and the demise of many of Chicago's Ogden Avenue businesses. Drivers were offered a faster course to the southwest suburbs and central Illinois. In the 1960s, construction began on Interstate 55, and in 1977 the "End of Route 66" signs on Jackson Boulevard came down. A few remaining restaurants and repair shops along Ogden Avenue still display Route 66 memorabilia, ensuring its years as a piece of America's most mythologized highway are never forgotten.

“La Calle Principal de América”
En la década de 1920, Estados Unidos se convirtió en una nación automovilística. A principios de la década, había 8 millones de automóviles en las carreteras, pero sólo 51,000 de los 4 millones de kilómetros de carreteras rurales del país estaban pavimentadas, lo que hacía que los viajes transcontinentales fueran

extremadamente lentos. A finales de la década de 1920, los estadounidenses poseían 23 millones de automóviles, y muchos de ellos conducían el accesible Modelo T de Henry Ford.

Más automóviles significaron más demanda de carreteras pavimentadas. En 1921, el Congreso aprobó la Ley de Ayuda Federal para Carreteras, que exigía una red de carreteras que cubriera todo el país. Unos años más tarde, se aprobaron planes de rutas interestatales para los 48 estados. La Ruta 66 se extendía más de 3,800 km desde Chicago hasta Santa Mónica, California. Cy Avery, el comisionado de carreteras de Oklahoma conocido como el "Padre de la Ruta 66", la apodó "La calle principal de América". Esta ruta se consideraba el camino principal entre los Grandes Lagos y la costa del Pacífico.

La Ruta 66 se estableció oficialmente en 1926. El tramo de Illinois de la Ruta 66 comenzó como una carretera de dos carriles conocida como SB14, que seguía la ruta del antiguo Pontiac Trail desde Chicago a St. Louis. Al principio, SB14 inició en Cicero, pero su designación como Ruta 66 aumentó el tráfico. Para adaptarse a esto, el punto de partida se trasladó a Michigan Avenue y Jackson Boulevard en Chicago. Ogden Avenue ha sido tradicionalmente una importante ruta de transporte hacia y desde Chicago. Esta calle es paralela tanto al brazo sur del río Chicago, que alguna vez fue la vía fluvial principal hacia el Mississippi, como a las vías del ferrocarril de Chicago, Burlington y Quincy. La era de

la Ruta 66 fue el apogeo de Ogden Avenue y los vecindarios que atraviesa. La Ruta 66 fue y sigue siendo un emblema de la cultura automovilística del país. Desde la década de 1920 hasta la de 1950, docenas de talleres de reparación, proveedores de neumáticos y concesionarios de automóviles instalaron tiendas a lo largo de la calle.

El desarrollo del sistema de carreteras interestatales, resultado de un proyecto de ley firmado por el presidente Dwight D. Eisenhower, provocó el desmantelamiento de la Ruta 66 y la desaparición de muchos de los negocios de Ogden Avenue en Chicago. A los conductores se les ofreció un rumbo más rápido hacia los suburbios del suroeste y el centro de Illinois. En la década de 1960, comenzó la construcción de la Interestatal 55, y en 1977 se quitaron las señales de "Fin de la Ruta 66” en Jackson Boulevard. Algunos restaurantes y talleres de reparación que quedan a lo largo de Ogden Avenue todavía exhiben recuerdos de la Ruta 66, lo que garantiza que sus años como parte de la carretera más idealizada de Estados Unidos nunca se olviden.

More about this marker. The marker is one of four unveiled in 2024 in coordination with NASCAR's second Grant Park 165 race, a street circuit through Grant Park in downtown Chicago on July 7, 2024. The other three are found along Ogden Avenue southwest of downtown. Although Route 66 is a U.S. highway, the marker's styling at the top actually is based on that used by the Interstate Highway System.

A brown sign denoting the beginning of Historic Route 66 is on a nearby lamppost; it replaced a previous version of this sign that was on a different post and was famously covered in stickers.
 
Regarding Chicago Route 66 / Ruta 66 de Chicago. The original eastern terminus of Route 66 was a block south of here, where Jackson Boulevard meets up with Michigan Avenue. However when that street was converted a one-way street, Route 66's easternmost point was moved up to Adams Street, which goes one-way towards the west.

Excerpt: "Officially named Route 66 on April 30, 1926, Jackson Boulevard became part of the Mother Road and began whisking generations of migrants and road-tripping vacationers westward. In 1955, however, the boulevard was transformed into a one-way street, and Adams Street at Michigan Avenue became the new launching point for
