Question: Which tunnel on Route 17 runs underneath the Hudson River?

 An integral conduit within the New York Metropolitan Area, it was designed by Norwegian-born civil engineer Ole Singstad and named after U.S. President Abraham Lincoln. The Lincoln Tunnel is an approximately 1.5 mi set of three tunnels under the Hudson River, connecting Weehawken, New Jersey and Midtown Manhattan in New York City.  It is one of two automobile tunnels built under the river, the other being the Holland Tunnel.  In 2016, the Lincoln Tunnel carried a daily average of approximately 52,632 motor vehicles (or 19,210,919 for the year). <SEP>  It runs 27.20 mi from Route 7/County Route 507 in North Arlington north to the New York border along Interstate 287 in Mahwah, where New York State Route 17 continues into New York.  Between Route 7 and Route 3 in Rutherford, Route 17 serves as a local road.  From Route 3 north to the junction with U.S. Route 46 in Hasbrouck Heights, the road is a suburban arterial with jughandles.  The portion of Route 17, from US 46 to Interstate 287 near the state line in Mahwah, is a limited-access road with all cross traffic handled by interchanges, and many driveways and side streets accessed from right-in/right-out ramps from the right lane.  For three miles (5 km) north of Route 4, well over a hundred retail stores and several large shopping malls line the route in the borough of Paramus.  The remainder of this portion of Route 17 features lighter suburban development. Route 17 is a state highway in Bergen County, New Jersey, United States, that provides a major route from the George Washington Bridge, Lincoln Tunnel and other northeast New Jersey points to the New York State Thruway at Suffern, New York.  The northernmost portion of Route 17 in Mahwah runs concurrent with Interstate 287 to the New York border. <SEP> Interstate 78 (I-78) is an east–west route stretching from Union Township, Lebanon County, Pennsylvania to New York City.  In New Jersey, I-78 is called the Phillipsburg–Newark Expressway and the Newark Bay Extension of the New Jersey Turnpike.  The highway runs for 67.83 mi in the northern part of the state of New Jersey from the Interstate 78 Toll Bridge over the Delaware River at the Pennsylvania state line in Phillipsburg, Warren County east to the Holland Tunnel under the Hudson River at the New York state line in Jersey City, Hudson County.  The Phillipsburg-Newark Expressway portion of I-78, formally called the Lightning Division Memorial Highway, runs from the Phillipsburg area east across rural areas of western New Jersey before entering suburban areas in Somerset County.  The road crosses the Watchung Mountains, widening into a local-express lane configuration at Route 24 as it continues through urban areas to Newark.  Here, I-78 intersects the mainline of the New Jersey Turnpike (I-95) and becomes the Newark Bay Extension, crossing the Newark Bay Bridge and continuing to Jersey City.  The route, along with Route 139, follows a one-way pair of surface streets to the Holland Tunnel. <SEP> Maryland Route 17 (MD 17) is a state highway in the U.S. state of Maryland.  The state highway begins at the Virginia state line at the Potomac River in Brunswick, where the highway continues south as Virginia State Route 287 (SR 287).  MD 17 runs 29.49 mi north from the Brunswick Bridge to the Frederick–Washington county line near Wolfsville.  The state highway serves as the main north–south highway of the Middletown Valley of western Frederick County.  MD 17 connects Brunswick and Wolfsville with Rosemont, Burkittsville, Middletown, and Myersville.  The state highway also connects those communities with the valley's main east–west highways, which include U.S. Route 340, US 40 Alternate, Interstate 70 (I-70), and US 40.
