Prepositions after verbs

Intersect with, at, by, in, or on?

Intersect with is the standard pattern when two lines, roads, or ideas cross. Other prepositions usually add location or context.

Quick answer

Which form is standard?

Use intersect with when one thing crosses another. At can show the point of intersection. In and on usually introduce context or location.

The highway intersects with Route 8 near the city.
The two paths intersect at the bridge.
