Bike lanes have taken 1/3 of the access roads to the bridges already causing traffic jams.  I have yet to see these lanes used extensively.  Bike riders don't pay road taxes, gas taxes and more. They have more rights than the motorist. Many riders don't follow traffic rules and surely bikes don't need main roads to move around.
Now taking out other efficient car routes.  City Hall needs to think big not just about the next election.
