Street closures unfriendly to cyclists

This is a typical street closure in Ottawa. Closed to cars … open to pedestrians … and closed to cyclists? 

Cyclists approaching this particular barrier on Spruce Street can choose to ride on the sidewalk (naughty naughty) or squeeze through the centre bollard or side spaces (provided no one is parked close).

Why not remove the centre bollards and let cyclists carry on through? Yes, I know some motorbikes would go through too (they already do, on the sidewalk, I watch them daily do this on the Elm closure on the next block).
