Mayor Michael Bloomberg proposed Sunday an $8 congestion fee for drivers who enter Manhattan below 86th Street.Bloomberg outlined an ambitious agenda for his final 32 months in office, proposing a new $7.5 billion freight tunnel under the Hudson River, and calling for the construction of new homes, among other initiatives.The mayor compared his determination to improve New York with Alex Rodriguez's powerful start to the 2007 baseball season."A-Rod didn't pay any attention to the doubters and the boo birds, and we've got to do the same thing," said Bloomberg. "We've got to go out there, keep our eyes on the ball, and for our children's sake, swing for the fences."He later joked, "we also have to ban all desserts and sweets."What he wasn't joking about was his mega plan to make New York City more habitable by 2030 with more housing, more trees, cleaner air, cleaner water and better energy.The mayor had 127 far-reaching proposals, with the most controversial being congestion pricing, where cars would be charged $8 and trucks $21 to drive into Manhattan below 86th St. from 6 a.m. to 6 p.m. He hopes to get more people to take mass transit and ease traffic flow.That charge would:-- Include any bridge or tunnel tolls people already pay-- Exempt drivers who bypass the business district on their way to another part of the city.-- Exempt taxi drivers, and possibly give discounts for people who live and work in the zone.Advocates said it's crucial for a city that's expected to add another million people in the next 20 years.Bloomberg's other proposals included more tickets for drivers who block the box, more red light cameras to enforce speeding laws, and the establishment of a regional transportation finance agency that would pay for things like a third LIRR track, and giving Metro-North riders access to Penn station."Things here are gonna grind to a halt if something is not done to relieve the congestion on New York City's streets," said Noah Budnick of Transportation Alternatives.Opposition has already formed in the boroughs outside of Manhattan, where some view Bloomberg as a Manhattan elitist.Former Queens Councilman Walter McCaffrey represents a group opposed to the idea."Those individuals who are not that well to do are going to find they're being hit with a $5,000 a year tax," McCaffrey said.Rep. Anthony Weiner condemned the proposal, saying, "It is a plan that is essentially a tax on people in the four boroughs not in Manhattan."On the city's traffic-clogged arteries, Bloomberg was not a popular guy."Next thing he's gonna charge us to cross the street," one driver said."It won't be easily done because there's always a resistance for people who live in the other four boroughs to pay to come to Manhattan," said former Mayor David Dinkins.Complaints like those echoed among drivers who'd heard that the mayor is about to propose tolls for vehicles entering Midtown Manhattan.This could set off a battle royale from here to Albany, where the legislature would have to approve the plan.
