<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">roadblock</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for obstacle that I've seen before include "difficulty" , "Blockage, hindrance" , "hold-up" , "Thing blocking progress" , "Maybe let" .)
