If you were to drive the entire span of I-90, you would have driven right around 3,100 miles, the longest of any US interstate. You would also have passed through 13 states, second most of any other interstate behind I-95.

Answer: China

China's interstate system is well over 59,000 miles long and connects many of the largest Chinese cities. The interstate started in 1988 and has grown rapidly over the years. China continues to invest heavily in its infrastructure, and roadways are one of its largest expenditures.

Answer: Interstate 20

I seriously doubt that Mr. Jones would ever send his team packing on a Greyhound bus, but if he did, and the Cowboys were taking on the Falcons in their home stadium, then I-20 would be the route to take. I-20 connects the cities of Florence, South Carolina and Kent, Texas. Dallas, Shreveport, Jackson and Birmingham are other major cities served by the interstate as it passes through Texas, Louisiana, Mississippi and Alabama respectively.

Answer: Dover, Delaware

Dover, Delaware can be accessed by several state highways, but not by the only interstate, I-95. I-95 crosses into Delaware from Maryland and the cities of Newark, Christiana, Newport, Wilmington and Claymont are reached before the interstate crosses over into Pennsylvania.

Answer: Arizona

Often called intrastate highways, since the highway is contained in a single state, these interstate systems are primarily used to connect major cities within a single state. There are several examples of these intrastate highways including I-17 which connects Flagstaff and Phoenix, Arizona.

Answer: Oregon

I-5 runs for nearly 797 miles from the bottom to top of California. It travels for 308 miles in Oregon and only for around 277 miles in Washington. I-5 literally runs from the US-Mexico border at San Ysidro to the US-Canada border in Blaine, Washington.

Answer: I-99

I-99 is one of the intrastate highways located continuously in Pennsylvania. I-96 begins in Bedford and passes through Altoona and State College before terminating in Bellefonte. I-99 is nearly 86 miles in length. The interstate was commissioned in 1998.

Answer: 80 mph

In rural areas of Texas along I-10 and I-20, and in rural areas of Utah along I-15, speed limits are 80 miles per hour. The vast majority of the US interstate system allows speeds up to 75 miles per hour. In several cases, speed limits can be even lower.

In parts of Cleveland and Washington D.C., the speed is limited to 50 miles per hour. In Wheeling, West Virginia, speed limits are lowered to 45 miles per hour in several locations. It's always careful to be aware of the speed limit wherever your travels may take you to avoid an unexpected speeding citation.
