The Oldest Covered Bridge in America

Ask which covered bridge in America is the oldest and you will get four confident answers, each from a different state, each backed by a historical marker, and each with a footnote that quietly undermines it.

New York says Otsego County. Pennsylvania says Union County, and then a second Pennsylvania bridge two counties away says no, actually, us. Ohio says Preble County. All four are standing today. All four are on the National Register. None of them can prove it.

Here is what the record actually supports, and why the question is harder than it looks.

The two 1825 bridges

Hyde Hall Covered Bridge — Otsego County, New York

Hyde Hall is a 53-foot Burr arch span over Shadow Brook, tucked inside Glimmerglass State Park near East Springfield. It is small, plain, and comfortably the most-cited answer to this question: the National Register, the World Guide to Covered Bridges, and the Historic American Engineering Record all date it to 1825, and New York State Parks threw it a 200th birthday party in 2025.

The complication sits inside its own paperwork. The Historic American Buildings Survey entry gives 1830, not 1825. The New York State Covered Bridge Society's own page says the bridge was "originally constructed in 1823" in one paragraph and built by Cyrenus Clark, Andrew Alden and Lorenzo Bates "in 1825" in another. The evidence underneath all of it traces back to a single 1996 thesis that cited original manuscripts placing construction circa 1825.

So the most authoritative answer in America rests on a date its own custodians write down three different ways.

Hassenplug Covered Bridge — Union County, Pennsylvania

Hassenplug crosses a branch of Buffalo Creek on North 4th Street in Mifflinburg, 80 feet of Burr truss, and it is also dated 1825. It is unambiguously the oldest covered bridge in Pennsylvania, a state with more covered bridges than any other, and it is described in the literature as "purportedly the oldest covered bridge in the United States."

Unlike Hyde Hall, Hassenplug is still doing the job. It carries traffic. It was restored in 2022, when the steel grate decking installed during a 1959 overhaul was pulled out and replaced with wooden planks.

Two bridges, the same year, no tiebreaker. Neither state's documentation engages seriously with the other's claim.

The other two contenders

Roberts Covered Bridge — Preble County, Ohio

Roberts was built in 1829 by Orlistus Roberts and Joseph Campbell over Sevenmile Creek. It claims three titles at once: oldest covered bridge in Ohio, second oldest in the United States, and the oldest of the six surviving double-barreled covered bridges in the country.

The third claim is the solid one. The second is where it gets complicated, because Roberts is not the only 1829 bridge still standing, and because Roberts today is not entirely the bridge that was built in 1829. Vandals burned it in 1986. It was rebuilt, then moved in 1990 into a city park in Eaton, where it now stands closed to traffic.

Rishel Covered Bridge — Northumberland County, Pennsylvania

Rishel is a 110-foot Burr truss over Chillisquaque Creek, dated 1830, and its National Register documentation states plainly that it "may be the oldest covered wooden bridge in the United States."

That is a remarkable sentence to find attached to a bridge dated five years after two others. It tells you how little confidence anyone has in anyone else's dates.

Why nobody can settle this

Three problems, and they compound.

A bridge and a bridge site are not the same thing. This is the big one, and it produces most of the bad numbers you will find online. Neff's Mill in Lancaster County is routinely dated 1824, which would make it older than every bridge above. A bridge was indeed built at that spot in 1824, by Christian Brackbill, and it was called Bowman's Mill Covered Bridge. It is not the bridge standing there now. The current structure was built in 1875 by James C. Carpenter, the year after Henry Neff bought the adjoining mill and gave the bridge its present name. The 1824 date describes a crossing, not a structure, and once that distinction blurs, a fifty-year error travels quietly from source to source.

Fire and flood reset the clock, or don't, depending who you ask. Roberts burned in 1986 and was rebuilt. Moscow Bridge in Indiana was destroyed by a tornado in 2008 and rebuilt to its 1886 design by 2010. Is a faithfully reconstructed bridge still the original? Covered bridge societies, the National Register and state tourism boards do not answer this the same way, and the answer moves bridges up and down every ranking.

The primary sources disagree with each other. The World Guide to Covered Bridges, the National Register, HAER and HABS are the four authorities everyone cites, and on Hyde Hall alone they produce two different years. Sugar Creek in Sangamon County, Illinois is the extreme case: its documentation places construction at either 1827 or 1880. Not a year apart. Fifty-three.

What can actually be said

Strip out the contested claims and a short list of pre-1835 survivors holds up reasonably well:

Two things stand out. The oldest survivors are overwhelmingly Burr arch spans, which makes sense: Theodore Burr patented the design in 1817, and its combination of arch and truss is simply more durable than the lighter forms that followed. And New Hampshire, which is nobody's idea of the covered bridge capital, quietly holds three of the seven.

The honest answer

If someone asks you which covered bridge in America is the oldest, the defensible reply is that Hyde Hall in New York and Hassenplug in Pennsylvania are both dated 1825, both are standing, and no surviving evidence separates them. Hyde Hall gets cited more often, largely because it sits in a state park with an active preservation society and a bicentennial to celebrate. Hassenplug gets cited less and is arguably the more impressive survivor, because it is still carrying vehicles across Buffalo Creek two centuries later.

Pick whichever one you can drive to.

Dates reflect National Register, HAER and World Guide to Covered Bridges documentation. Where sources conflict, the conflict is noted rather than resolved.
