It would connect Manhattan to Brooklyn and Queens and connect the two neighborhoods.

(New York City Department of Transportation) New York Mayor Bill de Blasio and his aides are considering a proposal for a new underground subway tunnel that would connect the city’s boroughs, Queens, and Manhattan.

The proposal would run under Manhattan and run beneath a large section of the Bronx, connecting to the Brooklyn-Queens Connector.

It could be used by subway trains, buses and commuter rail, as well as by private vehicles.

The tunnel would be connected to the Bronx Connector, the subway’s only route, through Queens.

The design would connect to the New Jersey Transit Blue Line, the city-owned rail line that carries millions of people daily.

It’s unclear if a tunnel would have to go beneath the Bronx or be built directly under it.

New York’s proposal to build a tunnel under the Bronx was first proposed by New York Gov.

Andrew Cuomo in 2013, but the proposal was not approved by the state Legislature.

Cuomo and his colleagues argued that the cost of building the tunnel was prohibitive, but state lawmakers rejected it in November, a year after Cuomo was elected.

The plan would have covered a total of about 3,000 feet of tunnel.

New Jersey Gov.

Chris Christie and his administration have long argued that building the New Bergen tunnel is a major step forward in New York and its ability to get commuters to Manhattan.

They have argued that such a tunnel could ease traffic congestion on the subway system and cut down on pollution.

In New Jersey and New York, there are no subway tunnels connecting Manhattan to Queens.

In 2017, the Bronx and Queens Connector were rerouted to separate stations at Queens and Brooklyn, and there is no tunnel connecting Manhattan and Brooklyn.

New tunnels have also been proposed for Philadelphia, Washington, D.C., Chicago, and other locations in the Northeast.

The new tunnels would have a maximum capacity of about 2,500 feet.
