Description
The viaduct provides a pedestrian-, bicycle-, and bus-free express route for taxicabs and other automobile traffic from 40th Street to 46th Street. From the south, traffic from Park Avenue or the Park Avenue Tunnel enters a ramp which rises a "T" above 42nd Street, over the street-level entrance to Grand Central Terminal below; side lanes of Park Avenue descend from 40th to end at 42nd Street. The elevated roadway then passes in front of Grand Central Terminal and around it to the east, passing the MetLife Building and descending again to ground level through the east portal in the Helmsley Building, arriving at 46th Street. Traffic coming from the north reverses this pattern: up a ramp through the Helmsley Building's west portal, past the MetLife Building, around the left to the front of Grand Central, and then to the right and down again to 40th Street, meeting side lanes coming from 42nd Street, where the viaduct connects to the Park Avenue Tunnel or to Park Avenue proper.

Famous quotes containing the word description:
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
