Interstate Highway System Main Auxiliary Suffixed Business Future

Primary Interstate Highways of the United States are numbered with one- or two-digit designations. Their associated auxiliary highways have three-digit numbers. Generally, odd-numbered routes run north-south, with lower numbers in the west and higher numbers in the east; even-numbered routes run east-west, with lower numbers in the south and higher numbers in the north. Routes divisible by "5" (for example, I-40 or I-75) are major routes, often running coast-to-coast or border-to-border.

Five pairs of numbers are duplicated throughout the system; the corresponding highways are separated by large distances which prevent confusion. The main list is followed by sections listing the primary Interstate highways in Alaska, Hawaii, and Puerto Rico.

Primary Interstate Highways

There are 68 primary Interstate Highways listed in the table below, and 43 of them have auxiliary routes.

Other Interstate Highways

In addition to the 48 contiguous states, Interstate Highways are found in Hawaii, Alaska, and Puerto Rico. The Federal Highway Administration funds four routes in Alaska and three routes in Puerto Rico under the same program as the rest of the Interstate Highway System. However, these routes are not required to meet the same standards as the mainland routes:

“

Highways on the Interstate System in Alaska and Puerto Rico shall be designed in accordance with such geometric and construction standards as are adequate for current and probable future traffic demands and the needs of the locality of the highway.^[3]

”

Hawaii

The Interstate Highways in the island of Oʻahu, Hawaii are signed with the standard Interstate Highway shield, with the letter "H-" prefixed before the number. They are fully controlled-access routes built to the same standards as the mainland Interstate Highways.

Like Alaska, Puerto Rico signs its Interstate Highways as territorial routes, and the numbers do not match their official Interstate Highway designations. Many of the territory's routes are freeway-standard toll roads.^[9]
