Question

A small stream runs
___(suitable preposition) that bridge ​

Answer 1

Answer:

I think below that bridge

Answer 2

Answer:

A small stream runs under that bridge.

Explanation:

To talk about something that is covered by something else, we use the preposition under.

whereas, below is used in cases where an object is not directly under another.

Here, the bridge covers the stream, thus, the preposition below will be used.

    A small stream runs under that bridge.
