You’ve probably seen it rising out of the mist while hauling down I-95 between Baltimore and Philadelphia. The Millard E. Tydings Memorial Bridge isn't just another stretch of asphalt. It’s a massive, 5,061-foot-long steel behemoth that sits 90 feet above the Susquehanna River. Honestly, if you’re a local, you just call it "the Tydings."
But there is a weird, almost eerie history behind this crossing.
Most people don't realize that this bridge was one of the very last things President John F. Kennedy did. On November 14, 1963, JFK stood right there at the Harford-Cecil county line to cut the ribbon. He used a pair of gold-plated scissors to open the "Northeast Expressway."
Eight days later, he was gone.
By 1964, the road he dedicated was renamed the John F. Kennedy Memorial Highway, but the bridge kept its original name. It honors Millard Tydings, a Maryland Senator who was basically the only guy brave enough to tell Joseph McCarthy to sit down and be quiet during the Red Scare.
Why the Tydings Bridge is Kinda Terrifying (and Iconic)
If you're driving a high-profile vehicle, you know the feeling. The wind kicks up. The steering wheel starts to feel light. It’s one of those "white knuckle" bridges.
Because it’s a deck truss design—meaning the support structure is underneath the road—the top is completely exposed. There’s no overhead cage to break the wind. When those gusts hit 55 mph, the Maryland Transportation Authority (MDTA) doesn't mess around. They’ll shut the whole thing down.
Here is the breakdown of why it’s a beast:
- Total Length: Over 5,000 feet. That is nearly a mile of bridge.
- The Drop: 90 feet of vertical clearance. It looks higher when you’re looking over the rail.
- Traffic Volume: We’re talking over 29 million vehicles a year.
- The Construction: It took only about 22 months to build back in the 60s, which is wild considering modern construction timelines.
The Toll Trap: How Not to Get Burned
Let’s talk money. This is where people usually get annoyed.
The Tydings Bridge is part of a "one-way" tolling system. If you are heading South (toward Baltimore), it’s free. You just cruise right over. But if you’re heading North (toward Delaware), you’re going to pay.
As of early 2026, the rates are still a bit of a sting if you don't have a transponder.
- E-ZPass Maryland: Usually around $6.00 for a standard two-axle car.
- Video Tolling (Pay-by-Plate): If you don't have E-ZPass, they’ll mail you a bill for roughly $9.00 or more.
- Commuter Plans: If you cross this thing daily for work, there are plans that drop the cost to $1.40 per trip, but you have to use a certain number of trips within 45 days.
The toll plaza used to be a nightmare of idling cars and exhaust. Thankfully, it’s all-electronic now. No more fumbling for crumpled dollar bills or digging through the center console for change. You just drive through at highway speeds and let the cameras do the work.
Structural Secrets: What’s Under the Water?
Back in 2011 and 2012, engineers realized the bridge had a "scour" problem. Basically, the Susquehanna River was eating away at the rock and dirt around the footings.
They had to do massive underwater repairs. Divers were working in 65 feet of water, fighting heavy currents and ice packs. It was a $33 million project just to make sure the legs of the bridge didn't shift.
Interestingly, they found that the bedrock under the river is actually non-erodible in most spots, but the layers of silt and "laitance" (a weak layer of cement and sand) were causing the issues. They ended up using cofferdams—basically big temporary walls—to dry out the work area so they could pour fresh concrete.
Is the Tydings Bridge Safe?
People worry. It’s an old bridge. It opened in 1963.
However, the MDTA puts it through a "hands-on" inspection every two years. That means inspectors are literally climbing the steel, looking for cracks, rust, and loose bolts.
The biggest real-world danger isn't the bridge falling down; it's the wind and the "narrow lane" feel. When it was first built, it only had four lanes. In 1972, they restriped it for six. That made the lanes feel a bit tighter than your average interstate.
Survival Tips for Your Next Crossing:
- Watch the signs. If you see "Wind Warnings" on the digital overhead displays, slow down. Seriously.
- Stay in the middle. If you're nervous about the height, the middle lane feels a lot more secure than being right up against the rail.
- Check the app. Use the DriveEzMD app or site before you leave. It’ll tell you if there’s a wreck or a wind restriction before you get stuck in the Perryville bottleneck.
- Keep your E-ZPass updated. Nothing ruins a trip like a $50 "administrative fee" because your credit card on file expired and your toll didn't go through.
What Most People Miss
The view.
Most drivers are so focused on the car in front of them that they miss the scenery. To the north, you have the massive Conowingo Dam. To the south, you see the Susquehanna opening up into the Chesapeake Bay. It’s one of the most beautiful points on the entire I-95 corridor.
If you want the view without the stress, take a detour through Havre de Grace. You can sit at the Promenade and look up at the bridge from below. It looks a lot more graceful when you aren't doing 70 mph next to a tractor-trailer.
Practical Next Steps
Before your next trip over the Susquehanna, log into your E-ZPass account and ensure your license plate is correctly linked to your transponder. If the transponder fails to read, having the plate on the account prevents the higher "Video Toll" rate. Also, if you’re traveling with a trailer or a boat, remember that your toll will jump significantly based on the number of axles—plan your travel budget accordingly for the northbound leg.
