The Tunnel That Connects New York City and Weehawken New Jersey Is Named After Which President? The Lincoln Tunnel Explained

The tunnel that connects New York City and Weehawken, New Jersey, is the Lincoln Tunnel, named after Abraham Lincoln, the 16th U.S. president. It carries New Jersey Route 495 under the Hudson River into Midtown Manhattan, linking Weehawken to the area near West 39th Street and Ninth Avenue. The Port Authority of New York and New Jersey owns and operates it, and roughly 120,000 vehicles use it on a typical weekday.

How the Lincoln Tunnel Actually Moves Traffic

The Lincoln Tunnel is not one tube but three, built in stages between 1937 and 1957. Each tube carries two lanes of one-way traffic, giving six lanes total across three separate bores. The center tube is reversible: its direction flips to favor the heavier flow, eastbound into Manhattan during the morning rush and westbound into New Jersey in the evening.

The governing mechanism is ventilation, and it shaped the tunnel's design more than any other constraint. Gasoline engines emit carbon monoxide, and a sealed tube under a river accumulates it fast. The tunnel uses longitudinal ventilation: massive fans push fresh air through the bore along the direction of traffic, so exhaust travels ahead of vehicles rather than lingering. Air supply and exhaust plants sit at the portals and on a mid-river ventilation building, moving millions of cubic feet of air per minute across the full length.

The roadway dips under the river and climbs back out, which matters for how the tunnel drains and vents. Water infiltration is continuous, so sump pumps run around the clock to keep the roadway dry and safe. Every one of these systems — ventilation, drainage, lighting, and fire suppression — exists because a subaqueous tunnel has no natural escape route for air, water, or smoke.

Put plainly: the tunnel is an engineered breathing machine as much as it is a road.

Quantified Context: Scale, Cost, and Daily Load

The numbers explain why the tunnel dominates the conversation about Hudson River crossings. The first tube opened in 1937, the second in 1945, and the third in 1957, so the full six-lane configuration has been in service for nearly seven decades. The tunnel is about 1.5 miles long from portal to portal, and it sits roughly 100 feet below the river surface at its deepest.

Traffic volume is the headline figure. On a peak weekday, the Port Authority reports tens of millions of vehicle crossings per year across its Hudson River facilities, and the Lincoln Tunnel alone handles a large share — on the order of 120,000 vehicles on a busy weekday, with the reversible center tube absorbing the directional surge. During the morning peak, the center tube carries eastbound traffic; by afternoon it reverses for the westbound exodus.

The operating budget is similarly large. The Port Authority funds maintenance, ventilation power, and staffing through tolls, and tolls have risen steeply across the bistate crossings over the past decade. Because the tunnel is operated by a bistate authority rather than a single city or state, its finances and governance span two states — a structural detail that shapes every capital project.

The scale matters for a simple reason: a single lane closure during peak hours can cascade into miles of backup on Route 495 and the approach ramps, because there is no redundant capacity nearby.

Edge Cases: When the Design Meets Its Limits

The tunnel's fixed capacity creates a set of predictable failure modes. A disabled vehicle in a bore blocks one of only six lanes, and the center tube cannot be reversed mid-cycle without clearing both portals. A fire is the most serious edge case: smoke travels with the ventilation flow, so the direction of air movement determines which escape route is safe. That is why the tunnel runs continuous ventilation even when traffic is light.

Height and hazmat restrictions are another hard limit. The tubes have clearance limits that exclude overheight vehicles, and placarded hazardous-materials shipments are restricted from the tunnels for safety reasons. An overheight truck that stops at the portal can force a full bore closure while it is turned around.

Weather and river conditions add stress. Storm surge and flooding in the Weehawken and Manhattan approach areas can overwhelm drainage, and the tunnel's pumps have finite capacity. The ventilation plants draw substantial electrical power, so a regional outage tests backup systems.

Red-flag warnings for drivers:

Never enter a tube if your vehicle exceeds the posted height limit; the portal sensors and clearance bars are there for a reason. Do not stop inside a bore for any reason other than an emergency; a stopped car creates a hazard in a confined space. If traffic halts and you smell smoke, follow the posted exit signs toward the nearest cross-passage rather than reversing. Do not carry placarded hazardous materials through the tunnel; alternate routes exist for a reason. Treat the reversible center tube as one-way in whichever direction is currently signed, and never assume the sign will match your return trip later.

Misconceptions About the Name and the Crossing

The most common misconception is that the Lincoln Tunnel and the Holland Tunnel are interchangeable names for the same crossing. They are not. The Holland Tunnel, which opened in 1927, connects Lower Manhattan near Canal Street to Jersey City, and it was named after Clifford Milburn Holland, the chief engineer who died before its completion. The Lincoln Tunnel, by contrast, connects Midtown Manhattan to Weehawken.

A second misconception is that Abraham Lincoln had any personal connection to the project. He did not; the tunnel was named in his honor decades after his death, consistent with the era's practice of naming major public works for presidents. The George Washington Bridge, upstream, follows the same naming logic.

A third misconception concerns the name itself: some assume the tunnel connects to a town called Lincoln in New Jersey. It does not. The New Jersey end is Weehawken, and the name honors the president, not a place.

A counterintuitive professional caveat: the tunnel's most important asset is not its roadway but its ventilation system. Engineers who study subaqueous tunnels will tell you that a tube with perfect pavement and failed ventilation is unusable, while a tube with rough pavement and working ventilation still moves traffic. That priority ordering surprises most drivers.

Comparing the Hudson River Crossings

The comparison shows why the Lincoln Tunnel punches above its weight: it is one of only two vehicular Hudson tunnels, and it is the only one serving Midtown.

A Timeline of the Crossing

The timeline shows a pattern: the tunnel was built incrementally as demand grew, and every major change since has been about managing that demand rather than expanding the roadway.

Practical Actions for Drivers and Planners

If you are planning a trip through the tunnel, the following thresholds and steps help.

Check the current toll schedule before you go; Port Authority tolls are collected electronically and have risen repeatedly, so budget for the posted rate rather than an old memory. Time your crossing against the peak windows: eastbound congestion peaks in the morning and westbound in the late afternoon, so crossing outside those windows saves time. Confirm your vehicle's height against the posted clearance before entering the approach; overheight vehicles cause closures. Use the real-time traffic feeds from the Port Authority and state DOTs to choose between the Lincoln Tunnel, the Holland Tunnel, and the George Washington Bridge. If you are routing freight, verify hazmat restrictions and clearance limits before dispatching through the tunnel.

For planners, the actionable threshold is capacity: the tunnel's six lanes are effectively fixed, so any proposal to add cross-river capacity has to account for the fact that the Lincoln Tunnel cannot be widened in place.

Limitations of What the Name Tells You

Knowing the tunnel is named after Abraham Lincoln answers the trivia question but not the operational ones. The name says nothing about capacity, tolls, ventilation, or the bistate governance that controls it. It also does not distinguish the Lincoln Tunnel from the Holland Tunnel in casual conversation, which is where most confusion arises.

The deeper limitation is that the tunnel's design is a snapshot of mid-20th-century engineering assumptions about traffic volume and vehicle emissions. Those assumptions have aged, and the tunnel now operates near or above its design capacity for long stretches of the day. The ventilation system, sized for the vehicle fleet of its era, is maintained and upgraded but remains the binding constraint on how the tube is used.

Because specific current figures for traffic volume, tolls, and capital projects change and are reported by the operating authority rather than tracked here, treat any number in this article as a magnitude, not a current reading. The stable facts are the name, the president, the Weehawken connection, the three tubes, and the reversible center bore.
