grade separation
A new overpass provides grade separation for the busy highway and the railway line.
Noun: A grade separation is a type of road or railway crossing where the intersecting paths are placed at different heights (levels or "grades") to allow traffic to flow without interruption. This is achieved using structures like overpasses (bridges) or underpasses (tunnels).
This term is used primarily in civil engineering, transportation planning, and urban infrastructure contexts to describe a solution for eliminating conflicts at intersections.
Examples: * The city council approved funding for a new grade separation at the busy railway crossing. * Grade separation is often the safest and most efficient way to handle intersecting traffic flows. * The highway project includes several grade separations to improve traffic flow.
- "to provide grade separation": To build or implement such a crossing structure.
- The new interchange will provide grade separation for all major turning movements.
- "grade-separated" (adjective): Describing an intersection or junction that uses this principle.
- The grade-separated interchange eliminated the need for traffic lights.
- Overpass (noun): A bridge that carries one road or railway over another.
- Underpass (noun): A tunnel that carries one road or railway under another.
- Interchange (noun): A complex of connecting roadways using grade separations.
- Flyover (noun): Synonym for overpass, commonly used in British English.
