While speaking to reporters Tuesday at the environmental summit in Copenhagen, Mayor Michael Bloomberg said it may just be a matter of time before his controversial congestion pricing plan resurfaces.

The plan would have charged drivers a hefty fee to enter Manhattan below 60th Street during the day.

"Come March, they're going to have to balance a budget, and I think any kind of revenue source is going to be on the table, and in fact it may still get done," Bloomberg said.

"They've now put park benches in the middle of Times Square, reduced Broadway traffic up and down town from four lanes down to one or two. And lower Broadway down to one lane. So he's created congestion," said Assembly Speaker Sheldon Silver.

The state legislature would have to sign off on any congestion pricing plan. More than 18 months ago, they failed to bring it to a vote.
