US-24 serves Manhattan, as well as the northern sides of Topeka and Lawrence. In Missouri, US 24 serves Kansas City, Independence, Buckner, Lexington, Waverly, Carrollton, Keytesville, Moberly, Madison, Monroe City, Palmyra and West Quincy. After becoming a two-lane road, it is then concurrent with Highway 5 in Keytesville (where it is called Jackson Street), and then passes by the city of Huntsville before turning into a four-lane highway and crossing U. John Jacob Astor was the original owner of the tract upon which Astoria was platted in 1836 and served as an important way station on the stage coach route. From Peoria, US 24 runs directly east (parallel to Toledo, Peoria and Western Railway) through a number of small towns en route to Indiana and Fort Wayne, Indiana, the next major metropolitan center. Route 24 runs east from the Illinois state line to Huntington. In Ohio, the roadway enters the state east of Woodburn, Indiana, near Antwerp.
The original designation for the current US-24 route in Kansas was U. US 24 crosses into Indiana at the state line east of Sheldon. Between the Indiana state line and Toledo, this portion of the roadway is known as the Fort to Port segment of the Hoosier Heartland Industrial Corridor.
With the designation of Route 66 as a strategic defense highway during World War II, the process of change accelerated.
While traffic to and from the great ordnance factories outside Chicago was critical to feeding the nation’s hungry war machine, it also devastated the Route 66 roadbed, which had not been built to sustain the constant flow of the heavy load bearing munitions trucks.
It originally ran from Pontiac, Michigan, in the east to Kansas City, Missouri, in the west.
Today, the highway's eastern terminus is in Independence Township, Michigan, at an intersection with I-75 and its western terminus is near Minturn, Colorado at an intersection with I-70. Route 24 runs west across the Quincy Bayview Bridge and east across the Quincy Memorial Bridge over the Mississippi River in Quincy.
Between Napoleon and Toledo, modern US 24 lies north of the Maumee River as a highway built to Interstate Highway standards.
There is also ready access to the nearest resorts of Ca'n Pastilla (5 miles) and Cala Mayor (4 miles).
Unlike many other segments of Route 66, Illinois Route 66 runs through a densely populated, highly developed State.
By the mid 1920s, Illinois already had a considerable infrastructure, including a modern road network.
When officially commissioned in 1926, Illinois Route 66 simply took over State Route 4, a pre-existing, heavily-used fully paved or “slabbed” two-lane road between Chicago and St. Thus, while the national span of Route 66 would not be completely paved until 1938, the Prairie State could boast from the very start that its segment of the Mother Road was mud free and “slab all the way.” At first glance, Route 66 may look inert and fixed, but a little investigation into its history (and archeology) reveals a dynamic process of change and transformation.
Due to population and development pressures, Illinois Route 66 received constant ongoing repairs, upgrades, widening, resurfacing, and even rerouting.
