The road was unobstructed, allowing for smooth traffic flow.
Unobstructed → It is formed from "un-" (meaning not) and "obstruct" (from Latin "obstruere", meaning to build against or block) and the suffix "-ed" (indicating a past participle). The word "unobstructed" means not blocked or hindered, allowing free passage or movement.
Think of 'not' ('un-') blocking something ('obstruct') — that's why unobstructed means free from any blockages.
