Discover a hidden piece of Ohio history at Hoover Dam in Westerville. During a recent drought, we uncovered a long-forgotten underwater road while exploring this scenic local favorite.

Our next adventure was extra special because it truly felt like an adventure. It was one of those unexpected discoveries that happen when you follow a spontaneous urge to pull over, get out, and see where a path might lead.

The Drive That Started It All

It began on a quiet Saturday evening drive down Sunbury Road in Westerville, Ohio. If you’re not from the area, you might not realize why this stretch of road is such a big deal. Sunbury Road runs parallel to Hoover Dam Reservoir, the largest body of water within fifteen minutes of the Columbus suburbs.

Despite its name, Hoover Dam is more than just a dam — it’s a local gem. It offers stunning views of serene water and forest, bike trails that connect to the Ohio-to-Erie Trail and others, a nature path, and even a walkable bridge where you can look down on the dam’s inner workings. For anyone who lives nearby, it’s a go-to spot for a scenic walk, run, or peaceful moment in nature.

A Surprising Sight

As we drove, something unusual caught our eye — the water level was shockingly low. Normally, the reservoir stretches right up to the parking area and bike path, but because of a recent drought, the water had receded dramatically. A large portion of the lakebed that’s usually underwater was now completely dry and walkable.

It might not sound like a big deal, but for anyone who loves exploring, getting to walk somewhere that’s normally underwater feels like unlocking a secret world.

Following a Hidden Path

We parked in a small gravel lot just off the road — one typically used by local anglers. It wasn’t an official park lot, which made it even better. There were no other cars, and that quiet sense of solitude made it feel like the start of something special.

As we stepped out, we noticed a narrow wooded path leading toward the water. I’ve run these trails for years and had never noticed it before. It was clearly a makeshift trail, worn into the earth by countless curious feet heading toward the waterline. The path was dim, a little eerie, and perfect for some pre-Halloween vibes.

Then, just as suddenly as it began, the trees opened — and we stepped out onto what felt like a secret beach.

Exploring the Exposed Shore

Before us stretched a wide, dry expanse that reached nearly halfway across Hoover Dam. The view was stunning. The sun was setting, bathing the landscape in shades of orange and violet that shimmered across the remaining water. It was one of those moments no photo could ever fully capture.

We started walking parallel to the road, climbing over rocks and patches of cracked earth. Every step felt surreal — this was normally the bottom of the reservoir, a place you’d never get to see.

The Underwater Road

Then the ground changed. What had been sand and rock slowly turned into asphalt and brick. We were still at least fifty yards from Sunbury Road, but it was clear we were walking on something man-made. And then we saw them — faint, faded lane lines.

After a moment of disbelief, we realized we were standing on an old submerged road. Later, some quick research revealed that this was part of the Old 3-C Highway, a section destroyed and flooded when Hoover Dam was built in 1955. I’ve lived in this area my whole life and had no idea this piece of history was hidden beneath the water. To not only find it but walk along it was an incredible experience.

Heading Back at Dusk

After about ten minutes of exploring the old road, the sunlight began to fade fast. The woods we’d come through would be tricky to navigate in the dark, so we decided to head back.

The walk back was quiet, the sound of crickets rising as the last light disappeared. It was a small, unplanned adventure, but one of the most memorable ones we’ve had. Getting to literally walk on a piece of hidden history — and seeing the dam in a way most people never do — made the evening unforgettable.

Final Thoughts

If you’ve never been to Hoover Dam, it’s well worth the trip. There’s plenty to do for all ages — hiking, cycling, birdwatching, fishing, or simply enjoying the views. And if you happen to visit during a dry spell, you just might find yourself walking on a piece of history that’s usually hidden beneath the water.
