What are the names of the two tunnels that connect Manhattan with New Jersey under the Hudson river?

For commuters traveling between New Jersey and Manhattan, two iconic underwater roadways make the daily journey possible beneath the Hudson River. The older of the two is the Holland Tunnel, an engineering marvel that opened in 1927. Connecting Jersey City with Lower Manhattan, it was tragically named in honor of its first chief engineer, Clifford Milburn Holland, who died before the project was finished. Its groundbreaking ventilation system, designed to clear toxic automobile exhaust, became a model for future tunnels around the world.

A decade later and further uptown, the Lincoln Tunnel was constructed to connect Weehawken, New Jersey, with Midtown Manhattan. Named for the 16th U.S. President, its first of three separate tubes opened to traffic in 1937. Together, these two tunnels are vital arteries in the New York metropolitan area's transportation network (Review), serving millions of vehicles each year and representing two distinct eras of American engineering and ambition.
