New York City is still more than a year away from becoming the first American metropolis to implement a congestion charge, but its plan to ease Manhattan traffic is starting to take shape. The tolling zone will cover the southern part of the island, starting at 60th Street. Vehicles will be charged a flat rate upon entering the area—it’s likely to be between $11 and $14 for cars—but the fee could vary depending on the time of day. Most of the expected $15 billion revenue through 2024 will help finance public transit improvements. It looks like the system will essentially replicate or expand the current E-ZPass toll system that’s already used on New York’s roads, bridges, and tunnels.
