Texas has the most interstate freeways per mile among U.S. states.

An interstate sign could be classified by polygon if allowed, since it has more than 3 sides, but since they are not equal, an interstate sign is technically not a polygon. If you ask an expert this same question, they would probably say "no". Hope this helps.
Interstate 40 (I-40) was officially completed in 1990. The last segment of the highway, which runs from Barstow, California, to Wilmington, North Carolina, was finished and opened to traffic that year. The construction of I-40 began in the 1950s as part of the Eisenhower administration's initiative to create a national interstate highway system.
Interstate 5 (I-5) is generally considered faster than Highway 99 due to its design as a major interstate highway, which allows for higher speed limits and less frequent stops. I-5 typically has more direct routes between major cities, leading to quicker travel times for long-distance journeys. However, traffic conditions can vary, so actual travel times may depend on the specific route and time of day.
