Welcome to My National Road Activity

Businesses flourished along U.S. highways, people traveled them for recreation and business, and the "Golden Age" went on for several years.

1.  Why did the major highways, called U.S. highways, lose popularity, and all the businesses along them closed for no business?
2.  What is happening to old historic U.S. highways now?


       Interstate 70 (I-70) is a major Interstate Highway in the United States that runs from a park and ride near Baltimore, Maryland, to I-15 near Cove Fort, Utah. I-70 approximately traces the path of U.S. Route 40 (US 40, the old National Road) east of the Rocky Mountains. West of the Rockies, the route of I-70 was derived from multiple sources. The Interstate runs through many major cities including Denver, Kansas City, St. Louis, Indianapolis, and Columbus.

       The sections of the interstate in Missouri and Kansas have laid claim to be the first interstate in the United States. The Federal Highway Administration has claimed the section of I-70 through Glenwood Canyon, completed in 1992, was the last piece of the Interstate Highway system, as originally planned, to open to traffic.

       The construction of I-70 in Colorado and Utah is considered an engineering marvel as the route passes through the Eisenhower Tunnel, Glenwood Canyon, and the San Rafael Swell. The Eisenhower Tunnel is the highest point along the Interstate Highway system with an elevation of 11,158 ft (3,401 m).

10 Interstate Highways Coming In The Next 10 Years

[It takes years or decades to plan and pass legislation to build an interstate highway.  Often, the new proposed highway will replace an older U.S. numbered highway.  Economic and environmental effects of the new construction have to be considered.  No one wants their personal property taken without choice.  Imminent Domain laws cause it to happen anyway.  Politics is a major factor, as with the sharing of a new Interstate over multiple state lines.  This list is a partial list of future Interstates and a little bit about their status.]

Recap of Development of the Interstate System:

The Interstate Highway System, since being signed into law by Dwight D. Eisenhower in 1956, has expanded from a small section in Missouri to a nationwide system of 47,000 miles. The original plans remain largely complete, but new economic requirements and opportunities exist that would only come about with the construction of new interstate highways.

Freeways provide for a slew of economic opportunities for the communities that lie along them. Most of the long distance car travel and freight in the United States take place along interstate highways. Many freeways in the United States do not have the status of Interstate Highways because of the lack of standards set by the Federal Highway Administration. New challenges of the 21st century along with the fact that the original interstate highway system being largely complete frees up funding for new highways in many states throughout the United States. New freeways are being planned because of the fact that the United States has changed economically and socially since the 1950’s.

Originally planned as a system of highways to evacuate people in times of war and moving supplies to front lines efficiently by way of a highway system, the interstate system has evolved in times of peace around the United States to bring economic and social benefits that were not seen when the system was first implemented.

Although some of the highways planned have clear benefits to the military and for civilian evacuation, many of the corridors actually have economic benefits as well, especially to regions of the United States that are isolated and impoverished. The following interstate highways are either in the planning phases or are in various stages of construction.

Interstate 49 is also under construction in many areas throughout the south. Currently, a section of Interstate 49 exists in Louisiana, which is the original corridor between Lafayette and Shreveport. Another section opened a few years ago in Missouri between Kansas City and Joplin.

Both of these sections will be connected through Arkansas and eventually span a distance between Kansas City and New Orleans. The biggest problem continues to be funding the corridor, but it is planned to be completed sometime in the 2020s.

Interstate 86 is under construction in the state of New York. It serves as a major connector between the Midwest and New York City without having to pay tolls through New York State. Originally slated to be complete in 2008, it has now been pushed back as far as 2018 due to slow funding sources.

This highway was written into law in the 1980’s and has been under construction since then. Currently, it is under construction or planned to extend from I-80 to Williamsport and on to Corning, New York, to connect it to I-86. It is also planned to extend south to Cumberland, Maryland and I-68.

Interstate 74 is currently in four segments. The original segment runs from Davenport and the Quad Cities on the border of Iowa and Illinois and goes to Cincinnati in Ohio to North Carolina sections

Interstate 11 is currently being constructed between two of the fastest growing cities in the (from) Southwestern United States, Las Vegas and Phoenix. The corridor will run southeast from Las Vegas to Kingman, Arizona over the newly completed bridge at the Hoover Dam. It will then follow the corridor currently being used by US 93 to Phoenix.

The bypass around Boulder City is underway and the freeway to Kingman is currently under construction as well. The freeway is also construction around Phoenix. It is a major economic corridor that was as recently as 2000 mostly a two-lane road with dangerous turns and security concerns with the highway crossing

Interstate 41 is currently being proposed as the official designation for the freeway will run from I-94 at Russell, Il (to) Green Bay and Milwaukee WS The highway is currently signed as U.S. 41.  Politics in Illinois and Wisconsin is slowing the connecting and renaming of U.S. 41.

Interstate 3 is known as the Third Infantry Division Highway, which is in homage to the division based in Savannah, Georgia. It is planned to run from Savannah, Georgia, to Knoxville, Tennessee. It would provide another freeway pass through the Appalachian Mountains and a path away from natural disasters such as hurricanes.

This freeway was signed into being in 2005 after Hurricane Katrina as a way to get supplies effectively to the coasts and people away from the coasts in anticipation of the storm. The numbering does not fit into the interstate highway numbering system, where lower digit highways are in the west. It has not yet been funded and faces a lot of criticism, especially due to environmental concerns.

Interstate 14 (representing the 14th Amendment of the United States Constitution) is a highway that is under consideration running initially from Augusta, Georgia to Alexandria, Louisiana.

In addition to being a powerful statement of the amendment on the history of the United States, it is also a strategic corridor connecting impoverished regions of the south and provides for a good East-West corridor for people getting away from the coast in anticipation of natural disasters such as hurricanes. The legislation allowing it was signed in 2005 after Hurricane Katrina as a way to plan for natural disasters. It also helps that the freeway connects some of the largest military bases in the country to one another.
