grade-separated
Roads without intersections
Grade-separated describes roads, railways, or pathways that cross at different levels rather than intersecting, typically using bridges or tunnels: a grade-separated interchange.
The design eliminates traffic signals and conflicts between crossing streams, improving safety and flow.
Common in highway systems and rail transit: The new light rail line is fully grade-separated.
