The disadvantage of the Whirlpool Bridge is having to drive into Niagara Falls (both Ontario and NY). I generally stop for a bathroom break in Beamsville and check the bridge crossing data. If not busy, I go to the Peace Bridge which gets you directly onto I-190 to the NY State Thruway. If it is busy, I use the Whirlpool Bridge with the Niagara Scenic Parkway (formerly Robert Moses Parkway) to I-290 to the Thruway, which costs an extra toll although I don’t remember in which direction it is charged.
