Florida

Interstate 75 begins its northerly journey at an interchange with State Road 924 and State Road 826 in Hialeah, a suburb of Miami. After an intersection with the Homestead Extension of Florida's Turnpike and an interchange with Interstate 595 and the Sawgrass Expressway, the interstate leaves the Miami metropolitan area and turns westward to travel through the Everglades along the tolled Alligator Alley, which brings the highway to the Gulf Coast and Naples, where it again heads north. Passing through Bonita Springs, Fort Myers, and Sarasota, Interstate 75 encounters a series of construction projects that will increase the lane count from two lanes in each direction to three. The freeway enters the Tampa Bay metropolitan area before the interchange with Interstate 275 northbound, which handles St. Petersburg-bound traffic. Within the Tampa metro are three more major junctions: One with the Lee Roy Selmon Crosstown Expressway which carries traffic into downtown Tampa, one with Interstate 4 which carries traffic across the center of the state to the East Coast, and another as Interstate 275 traffic defaults back onto northbound. The freeway proceeds to enter suburban portions of Pasco, Hernando, and Sumter counties on its way to Ocala and Gainesville. At Lake City, Florida the "Christopher Columbus Transcontinental Highway", Interstate 10, intersects with Interstate 75, providing routes towards Jacksonville, Florida, Tallahassee, Mobile, Alabama, and points westwards. Afterwards, the northmost stetch of Interstate 75 in Florida exits the "Sunshine State" into southern Georgia.

Georgia

Interstate 75 enters Georgia near Valdosta, and it continues northward through the towns of Tifton and Cordele until it reaches the Macon area, where it intersects with Interstate 16 eastbound towards Savannah. For northbound traffic wishing to avoid potential congestion in Macon, Interstate 475 provides a relatively straight bypass west of that city and Interstate 75's route. After Macon it passes the small town of Forsyth. The freeway reaches no major junctions again until in the Atlanta metropolitan area. The first metropolitan freeway met is Interstate 675, then followed by the Atlanta "Perimeter" bypass, Interstate 285. This Interstate is duplexed with Interstate 85 through the central area of Atlanta. After the two Interstates split, Interstate 75 makes a beeline towards Interstate 285 and the major suburban city of Marietta. North of Marietta, the final major junction in the Atlanta metropolitan area is with the Interstate 575 spur. Interstate 75 next traverses the hilly northwestern Georgia terrain as it travels towards Chattanooga, Tennessee.

A section of the interstate just north of Atlanta, near the northern interchange with Interstate 285, has 15 through lanes, making it the widest roadway anywhere in the Interstate Highway System.[3]

Tennessee

The freeway enters Tennessee directly in the Chattanooga metropolitan area, where it intersects with Interstate 24. Exiting Chattanooga to the northeast, Interstate 75 passes through an area known for dense fog. Twelve people were killed and 42 were injured in a 99 vehicle accident on that stretch of I-75 in heavy fog on December 11, 1990[4]. Interstate 75 does not meet any other highways until it is multiplexed with Interstate 40 and heads eastbound. Together, they enter the outskirts of Knoxville, where Interstate 75 multiplexes itself with a different road, this time Interstate 640, but only for a short time. When the two meet Interstate 275, Interstate 75 becomes its own freeway and heads north towards the Kentucky border. On the journey northward from Knoxville to the Kentucky border, interstate 75 encounters some of its highest points of elevation through the Cumberland Mountains and Cumberland Plateau region, cutting through the uppermost peaks and ridges of the mountains.

Kentucky

Interstate 75 continues northbound through the hilly and rugged terrain of the Cumberland Plateau region of Kentucky passing through London, KY and Richmond, KY eventually reaching Lexington, where it briefly runs coterminiously with Interstate 64 before splitting off for Cincinnati, Ohio. Near Walton, Interstate 71 merges with Interstate 75, making for yet another multiplexed portion of freeway. Interstate 275, which is the Cincinnati beltway, is then intersected by Interstate 71/75. After passing through Covington, the freeway crosses the Ohio River via the lower level of the Brent Spence Bridge and continues into Cincinnati.

Ohio

Immediately after entering Cincinnati, Interstate 71 separates from Interstate 75, taking a more easterly routing through the city, while Interstate 75 remains generally northbound throughout the metropolitan area. Interstate 74 westbound, Ohio State Route 562 eastbound, and Ohio State Route 126 all intersect the freeway as it makes its way northward. In the Arlington Heights neighborhood of Cincinnati, Interstate 75 sees a carriageway split for a few miles. After another interchange with the Interstate 275 beltway, the freeway continues in the metropolitan area, passes through Middletown and heads towards Dayton, where Interstate 675 and Interstate 70 have interchanges. After exiting Dayton, Interstate 75 makes its way northbound through Ohio, passing through the smaller cities of Lima, Findlay and Bowling Green before finally reaching Toledo, located on the Michigan border. Interstate 475 is met first south of the city, and then the cross-country highways of Interstate 80/Interstate 90/Ohio Turnpike. Interstate 475 then meets with 75 again. Interstate 280 is the last major junction in Ohio; the freeway crosses into Michigan soon afterwards.

Mackinac Bridge

Michigan

Interstate 75 hugs the western shore of Lake Erie upon entering Michigan—until about Monroe, when it heads westward and prepares to enter Detroit and its surrounding suburbs. Yet another I-275 is met as the freeway goes deeper into the Detroit metropolitan area, and no other major junctions are present until downtown. Once downtown, Interstate 75 meets the Ambassador Bridge to Windsor, Ontario, Interstate 375 (Chrysler Freeway), I-94, I-96, M-10 and M-8 (Davison Freeway). I-696 also intersects I-75 in the northern metro area. When the freeway reaches Pontiac, there is a junction with M-59; and further north in Flint, the interstate meets I-475 and I-69. The freeway then heads north towards Saginaw, where I-675 acts as a spur route into the city. Further north in Bay City, the major junction of US 10 exists, providing access to Midland as well as downtown Bay City. The last major interchange occurs at 4 Mile Road just south of Grayling where US 127 northbound ends with traffic merging onto northbound I-75 and the southbound starts taking drivers through the center of the state granting easier access to cities such as Clare, Mt. Pleasant, Lansing, and Jackson. At Mackinaw City, I-75 crosses the Mackinac Bridge to reach the Upper Peninsula. It is the only Interstate located in the Upper Peninsula of Michigan, and it continues to where the road terminates at the Canadian border in Sault Ste. Marie.

On the Canadian side, drivers must use a series of city streets in Sault Ste. Marie, Ontario to reach Highway 17, the local route of the Trans-Canada Highway.

On July 15, 2009, a fuel tanker exploded under an overpass on 9 Mile Road in Hazel Park resulting in the overpass collapsing onto I-75.[5][6]

History

This limited access highway that was planned in the 1950s roughly follows the general route of many older at-grade highways, including U.S. Route 2, U.S. Route 27, U.S. Route 25, and U.S. Route 41, among others. Some of these older U.S. Routes (several of which are still in existence) previously had replaced the eastern route of the old Dixie Highway.

Interstate 75 was intended to end at Tampa in the original interstate highway plans. However, vast population growth in southwestern Florida (e.g. Ft. Myers, Naples, etc.) and a desire to link the Tampa Bay Area with South Florida, called for a new expressway artery.[7] At first, Florida state legislators proposed a toll in the corridor, but by 1968, it was cancelled in favor of the extension of I-75 southwards.[8] Next, it was decided to link I-75 from Naples to South Florida with an upgraded version of an existing private toll road, the Alligator Alley, and then connect it with Interstate 95 in North Miami, although due to local opposition, I-75 ends a few miles short of I-95.

The final stretch of Interstate 75 was completed in 1986 in Dade (present Miami-Dade) and Broward Counties in Florida, but the last stretch to receive the I-75 signage was a reconstructed (rebuilt with more lanes) Alligator Alley in 1993.

Interstate 75 is a 1,786-mile long interstate highway in the midwest and southeast United States that runs from Sault Ste. Marie, Michigan at the Canadian border to Miami, Florida. It passes through the major cities of Detroit, Cincinnati, Atlanta, Tampa and Miami. Its southern terminus is at Florida State Routes 826 and 924 near Miami, and its northern terminus is at the Sault Ste. Marie International Bridge at the border of Canada.

Path

I-75 passes through six states, going south to north: Florida, Georgia, Tennessee, Kentucky, Ohio and Michigan.

Florida

I-75 is the longest Interstate highway in Florida, at 472 miles. It begins at the southern tip of Florida, at SR 826 (the Palmetto Expressway) near Miami. After passing through the suburbs of Miami and Ft. Lauderdale, it goes through the Everglades, goes through Naples, and runs parallel to the west coast of Florida through the Tampa area. It intersects with Florida's Turnpike and runs slightly northwest to the Georgia state line.

Michigan

I-75 enters Michigan in the Toledo metropolitan area and goes close by the shore of Lake Erie until it reaches Detroit and its suburbs. It meets Interstate 275, a western bypass route, about 30 miles south of Detroit. It then goes through downtown Detroit and through its suburbs before heading north to Flint. From this point it begins to take a northwest path through Saginaw and the northern part of the state before crossing the Mackinac Bridge and entering the Upper Peninsula. At Mile 395 it crosses the International Bridge to Canada.

EXIT LIST

Exits 2-3 - Summit Street in Erie Township.

Exit 5 - Erie Road, leading to Erie and Temperance.

Exit 6 - Luna Pier, a small town on the northwest coast of Lake Erie.

Exit 9 - South Otter Creek Road in La Salle.

Exit 20 - Junction with Michigan's I-275, a 35-mile long freeway that bypasses the city of Detroit and goes north to I-96/I-696 in the Farmington Hills, a western suburb of Detroit.

Exit 35 - Telegraph Road, or US Route 24, a long expressway that goes through the western suburbs of Detroit and south to a couple miles past the Ohio border.

Exit 41 - M-39, the Southfield Freeway, another freeway through the western suburbs of Detroit.

Exit 48 - Interstate 96 West.

Exit 51B - M-3, Gratiot Avenue, a major northeast-southwest thoroughfare through downtown Detroit and its eastern suburbs.
