(OP)
Just a cool photo of a view down the Chain Bridge over the Potomac at Washington circa 1865.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

If you're ever in the Allentown PA vicinity, go to Covered Bridge State Park. There are two well preserved Burr Bridges from the 1850's - and still open to traffic.

Those were some fun shop drawings to check.

Aren't a bunch of the surviving covered bridges around the US made with the Burr design? Many aren't open to traffic, but many still are (for instance, western Indiana). Remarkable design-use the natural strength of the arch, combined with the practicality of a standard truss design. Does the bridge collapse without the arch?

Thanks.
