Webster's 1913 Dictionary
\Ob*struc"tion\, n. [L. obstructio.]

   impediment; a hindrance.

         obstruction, and to rot.              --Shak.

Syn: {Obstacle}; bar; barrier; impediment; clog; check;

Usage: {Obstruction}, {Obstacle}. The difference between
       these words is that indicated by their etymology; an
       obstacle is something standing in the way; an
       obstruction is something put in the way. Obstacle
       implies more fixedness and is the stronger word. We
       remove obstructions; we surmount obstacles.

             Disparity in age seems a greater obstacle to an
             intimate friendship than inequality of fortune.

             The king expected to meet with all the
             obstructions and difficulties his enraged
             enemies could lay in his way.     --Clarendon.
