The term 'not obstructed' can be described by three crossword solutions: 'unbarred' (8 letters), 'UNCLOGGED' (9 letters) and 'UNHINDERED' (10 letters). Unbarred means to remove a bar or obstacle that is blocking something, while UNCLOGGED implies the removal of an obstruction that is clogging something. UNHINDERED, on the other hand, suggests that there is no impediment or hindrance in the way. All three words describe the concept of not being obstructed.
