Not sure what bridge this has you crossing in Niagara Falls but I'm guessing the Lewiston Queenston, every map program takes you across that bridge, you and every other person that has looked up directions, takes an extra 30-60 minutes to cross that bridge vs the other bridges. I would suggest taking the Peace bridge in Buffalo, the Rainbow bridge in NF is a faster bridge to cross but doesn't land you on a highway, does put you in the middle of tourist central if you had any plans to stop and see the Falls though.
