Despite support from the city's leading lawmaker on transportation issues, Mayor Bill de Blasio doesn't think Albany is willing to enact tolls on East River bridges.

"I've said it's something that is worth looking at," de Blasio told reporters Monday, "but, as you've heard, right now in Albany there's no appetite for it."
