How many interstates are there in the us

For example: Interstate 25 runs the east-west direction while Interstate 10 runs the north-south direction. However, some of them do have bypass routes, but the bypass routes are part of the main Interstate Highway System and the main Sintopian Interstate Highway System. For example: Interstate traverses around Castineland while Interstate traverses around Sintopia City.

There are 20 Interstate Highways in Sintopia listed in the table below. Seven of them are bypass routes beltways. These highways also have nicknames for the construction helpers for Queen and they are named after the cities they go through. Route Interstate 21 Interstate 23 Interstate U. Route 47 U. Route 0 U. Route 1 U. Route 2 U. Route 10 U. It runs through 10 states and includes Denver, Kansas City, St.

Louis, Indianapolis, Columbus, Pittsburgh and Baltimore, but it also contains a few notable attractions other than major cities.

I touches the Eisenhower Tunnel, which is the the highest point in the entire interstate system at 11, feet, as well as the highest vehicular tunnel in the United States. I was the first interstate to build through previously uncharted territory when it went through Utah's San Rafael Swell, and contains the longest stretch of interstate with no services.

It also contains one of the few gaps in the interstate system, a stretch in Breezewood where portions of the Pennsylvania turnpike that predate I resulted in a quarter-mile gap known as US I is the longest of the odd numbers, which are reserved for north-south routes, with numbers increasing from west to east. I holds plenty of distinctions, the least of which is the longest north-south interstate in the country, and the most states covered, with 15 plus Washington, D.

I also hits the most densely populated regions of the country as it moves through Miami, Baltimore, Washington, D. The interstate hangs close to the Atlantic Ocean, but dives inland at points in Georgia and the Carolinas and comes with a tenth of a mile of Washington, D.

It only takes I six states to reach from Miami to the border with Canada in Michigan. An original Interstate era sign directing motorists to the Chicago Skyway and the Northwest Indiana Interstate network. Oklahoma Veterans Memorial Highway System sign posted at the northbound welcome center near Thackerville. The south split of Interstate and U. Illinois 25 active routes 2, I , I , I New York 31 active routes 1, In this way, the Act guaranteed construction of all segments on a "pay-as-you-go" basis, thus satisfying one of President Eisenhower's primary requirements, namely that the program be self-financing without contributing to the Federal budget deficit.

The Federal-Aid Highway Act of called for uniform geometric and construction standards for the Interstate System. Examples of design standards for the Interstate System include full control of access, design speeds of 50 to 70 miles per hour depending on type of terrain , a minimum of two travel lanes in each direction, foot lane widths, foot right paved shoulder, and 4-foot left paved shoulder. Initially, the design had to be adequate to meet the traffic volumes expected in Later, the requirement was changed to a more general year design period to allow for evolution of the System.

The Interstate route marker is a red, white, and blue shield, carrying the word "Interstate", the State name, and the route number.

Major Interstate routes are designated by one- or two-digit numbers. Routes with odd numbers run north and south, while even numbered run east and west. For north-south routes, the lowest numbers begin in the west, while the lowest numbered east-west routes are in the south.

By this method, Interstate Route 5 I-5 runs north-south along the west coast, while I lies east-west along the southern border. In two cases, a major route has two parallel or diverging branches. In those cases, each branch is given the designation of the main route, followed by a letter indicating a cardinal direction of travel east, west, etc. The two branches merge at Denton to reform I
