What does straight through at an interchange mean?
1 Answers
Straight through at an interchange generally means that you can proceed straight or make a left turn at the upcoming intersection. Below is a partial introduction to interchanges: Introduction: An interchange is a three-dimensional crossing where roads intersect at different levels. It directs conflicting traffic flows onto roads at different elevations, ensuring both smooth traffic flow and safety. Components: An interchange mainly consists of three parts: the overpass (or underpass), the approach, and the ramp. The overpass is a bridge that crosses over or tunnels under another road. The approach is the section of road that connects to the overpass. The ramp is the section that connects the road to the lower level of the overpass. Cloverleaf interchanges also include ramps that connect the upper and lower intersecting roads.
