- What is an Interchange?
An interchange is a grade-separated intersection (one road passes over another) with ramps to connect them. For busy roads this is a necessity to keep traffic moving. Typically, interchanges are designed for the projected traffic for the region. This makes some designs more beneficial than others with respect to operation, right-way impacts, etc.
A complete interchange has to provide access to and from any direction from each facility. Full freeway-to-street access with a conventional interchange requires a minimum of four ramps, to get on and off in each direction. In Florida, full interchanges are required for a future design. Partial interchanges are not allowed unless special needs are displayed (park and ride, by-pass routes, etc.)
An exit ramp, or off ramp, leaves the main roadway for another road; an entrance ramp, or on ramp, enters the roadway. These terms make the most sense when one freeway intersects a surface street; entrance and exit are from the point of view of the freeway.
An interchange is a simple solution to a capacity problem. Safety, cost, environment, development and politics can vary at each site. Many interchanges are slight variations of a few basic types. The most commonly used types of interchanges are the diamond, cloverleaf and directional.
The existing I-75/US 301 loop-style interchange will be reconfigured to form a tight diamond. The diamond interchange is the most common type where a major facility intersects a minor highway. The design allows traffic to flow freely on the major highway but creates at-grade intersections on the minor highway with the ramps.
