It's unclear if congestion pricing will become a reality soon as Assembly Speaker Sheldon Silver stayed clear of Albany. The latest AP report says Silver only agreed to sign a letter to the feds, with Senate Majority Leader Joseph Bruno and Gov. Eliot Spitzer, saying the state will investigate opponents' concerns. Silver said that should keep the plan, more so the $500 million attached to it, alive, according to the latest report. No word yet from the federal Department of Transportation, which is in charge of doling out the funds.
