Interstate 4 Description

Interstate 4 (I-4) is a 132.298 miles (212.913 km) intrastate Highway located entirely within the US state of Florida. It goes from I-275 in Tampa, Florida to I-95 at Daytona Beach, Florida . It also has the Florida Department of Transportation (FDOT) designation of State Road 400 (SR 400), but only a small portion of the route is signed at the east end. I-4 is currently the lowest-numbered Interstate Highway within the contiguous 48 states. The area that surrounds I-4 is often referred to as the I-4 Corridor.

I-4 maintains a diagonal, northeast–southwest route for much of its length, although it is signed east–west. The 132-mile (212 km) route begins with an interchange with I-275 in Tampa and continues east toward I-75.

After passing through the eastern suburbs of Hillsborough County, it crosses into Polk County, entering the Lakeland area, intersecting with the Polk Parkway twice before entering Polk City.

At this point, the interstate starts a turn toward the northeast where it intersects with the Orlando area cutting the city through at a diagonal direction going northeast/southwest. The route provides access to all of Orlando’s theme parks including Disney World and Universal Studios, as well as nearly all of Orlando’s toll roads, including Florida’s Turnpike. Throughout most of Orange County and Seminole County, I-4 travels in a roughly north–south direction. This causes endless trepidations for outsiders, since the exits are named according to I-4′s generally west–east orientation.[4]

Right before the eastern terminus, I-4 switches to a mostly east–west route in order to connect with traffic from and to I-95. At an interchange with I-95 in Daytona Beach, I-4 terminates; however, SR 400 continues eastward into Daytona Beach.

Named Beville Road, it runs along the boundary between the cities of Daytona Beach and South Daytona. Sections of Beville Road is classified a “Scenic Thoroughfare” by the City of Daytona Beach.
