unobstructedly

In clear passage

Without obstruction or hindrance; in a way that is free from barriers or interference.

The adverb is rare and awkward—*unobstructed* typically appears as an adjective modifying nouns directly: an unobstructed view, unobstructed access.

When the adverb is needed, *without obstruction* usually sounds more natural: Traffic flowed without obstruction.
