Final answer:
The question inquires about a rapid transit tunnel under the East River at a specific, but not provided, street in New York City. There are multiple subway tunnels under the East River, and without the street number, one cannot confirm the absence of a tunnel.
Step-by-step explanation:
The question you've asked pertains to the infrastructure of New York City's rapid transit system, specifically with regard to the existence or absence of a tunnel under the East River at a certain street. While the street number is not provided in your question, it should be noted that there are several tunnels under the East River that connect Manhattan to Brooklyn and Queens, servicing various subway lines. For instance, the Lexington Avenue line (4, 5, 6 trains) has a tunnel at 14th Street, and there are additional tunnels at 42nd, 53rd, and 63rd streets, among others. To provide an exact answer, the street number would need to be specified. However, without this key detail, it is impossible to provide a definitive answer.
