Traveling Along Interstate 75 Trivia Quiz

Answer: Florida

Growing up in South Florida, I actually drove to the southern terminus of I-75 many times to travel through Dade County on SR 826 which is commonly known as the Palmetto Expressway. In Broward County of South Florida, there is an East-West highway known as I-595 the links several major north-south highways including I-75, I-95, and the Florida Turnpike.

Answer: Sault Ste. Marie International Bridge

Interstate 75 ends at the Canadian border where the roadway then becomes Huron Street in Sault Ste. Marie in Ontario. In 2016, the population of Sault Ste. Marie in Ontario was about 73,000 whereas the Sault Ste. Marie in Michigan had a population of just 14,000.

The state of Michigan actually has the second-longest border of any U.S. state with Canada at 721 miles through numerous junctions on both its Upper and Lower Peninsulas.

Answer: Macon

With a population of about 154,000 in 2014 the city of Macon was the fifth-largest in the state of Georgia and due to its central location it is known as the "Heart of Georgia". In addition to Macon, I-75 also passes through the cities of Atlanta and Valdosta within Georgia.

The Atlanta portion of I-75 runs for about 15 miles and due to its heavy traffic some areas have as many as 15 lanes.

Other Gulf Coast cities along I-75 in the state of Florida include Fort Myers, Punta Gorda, Naples, Sarasota, and Venice. In total, I-75 runs for 471 miles in the state of Florida, the longest distance of any interstate in any state east of the Mississippi River.

In total, I-75 travels through Kentucky for 192 miles and the largest city in the state it goes through is Lexington. Through nearly its entire length in Kentucky, I-75 runs parallel to highway US 25. After passing through the city of Covington, Kentucky, I-75 crosses the Ohio River and then enters the city of Cincinnati, Ohio.

Answer: Toledo

In 2010, Toledo was the fourth most populous city in Ohio with a population of 287,000. The phrase "Holy Toledo" is derived from Toledo, Spain, which is known for its churches. In the United States, the phrase is typically used to describe something unbelievable.

Answer: Walter Chrysler

The southern and central areas of I-75 within Detroit are known as the Fisher Freeway. The Walter P. Chrysler Freeway runs northward from Detroit to the Oakland-Genesee county line. Interestingly, I-75 is officially known as the American Legion Memorial Highway through its course in Michigan but on most signage the I-75 designation appears.

Answer: Zilwaukee Bridge

Rising to a height of 125 feet, the Zilwaukee Bridge has a length of 8,000 feet. Expanding to six lanes, the Zilwaukee bridge replaced a bridge originally constructed in 1960 that could not accommodate as much traffic.

Answer: Alligator Alley

Comically, during construction the name Alligator Alley was actually meant derogatorily since the American Automobile Association initially believed the road would be more useful for alligators than cars. Eventually the name stuck and in 1966 the name was officially adopted for the approximately 80 mile portion of I-75.
