After Congress passed the Federal Aid Highway Act (FAHA) of 1956, Dwight David Eisenhower signed the bill into law. Hawaii actually has THREE "interstates": H1, H2, and H3, which connect vital military bases on the island of Oahu.
Oddly, Alaska does NOT have a highway that is considered to be part of the interstate highway system.
Interstate H-1
NO
45 miles per hour
Maui is in Hawaii, an island, not accessible by road. However, Hawaii does have two interstate highways. Hmmm....
I assume you already know about Hawaii?...Improving the answer: there are 2 states not served by the interstate, Alaska and Hawaii. However, there are 6 state capitols not served by the interstate. Juneau, AK, Honolulu, HI, Dover, DE, Pierre, SD, Jefferson City, MO, and Carson City, NV.
Interstate 5
H-1, H-2, H-3 and H-201.
The average speed limit in the United States is typically around 55-65 mph on highways and interstates, and 25-35 mph on urban roads. However, speed limits can vary greatly depending on the specific location and road conditions.
Technically, none- since the term Interstate means a road that goes to other states- and since Hawai'i is a group of islands, no roads go out of Hawai'i. It is several thousand miles to another state. But there are 4 expressways on the Island of Oahu that are designated H-1 thru H-4, they were funded by the Interstate Highway program.
