I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">broad street</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for avenue that I've seen before include "Road leading to a house" , "A broad wide street" , "Thoroughfare, boulevard" , "Way of approach" , "A broad thoroughfare as in New York" .)
