Was there ever a land bridge between Europe and America?
"No. The distance is far to great to drive even if their was a bridge. With the modern world's easy access to the plane their is no need to build one today."- Godot-59
The question doesn't ask about a physical man-made bridge, but a land bridge. An example of a "land bridge" might be the area currently beneath the North Sea that cuts the United Kingdom off from mainland Europe. This has been named "DoggerLand", as the area is known as Dogger Bank, and in shipping terms as Dogger. It's known to have been in use for animal and human passage due to the bones dredged up by Dutch trawlers. Remember though that this area is all part of the European continental shelf, and not as deeply submerged as the ocean bed beneath the Atlantic.
So to answer the question - No, there probably has never been a land bridge between Europe and America. They sit on two separate continental shelves, and the oceanic depths are too great in vast areas to have ever been exposed by falling sea levels during ice ages. It is theoretically possible that a crossing over the polar caps could have been made during ice ages, though the complete lack of vegetation and the distances involved, not to mention the sheer hostility of the environment make the actuality all but impossible. It would be an epic task for humankind with modern knowledge, let alone in prehistory.
However with all this said, it is projected that there may have been a time when earth was young that the continents were very close, and perhaps conjoined in places. At this time, if indeed it existed as reflected in contemporary projections, it would have been possible to pass from one point to another that later became separate continents, however this time would pre-date most known forms of life on this planet, let alone mankind.

What is covered with verdigris?
Verdigris is a greenish-blue pigment that forms on copper, bronze, and brass due to the oxidation process when these metals are exposed to moisture and air over time. It can cover surfaces like sculptures, roofs, and architectural elements made of these metals, often resulting in a distinctive patina that can be both aesthetically pleasing and protective. While verdigris is commonly associated with art and design, it can also indicate corrosion and deterioration of the underlying metal if left untreated.
Why arn't solgers and bands allowed to march over bridges?
Soldiers and bands break step so as not to reinforce the fundamental vibration frequency of the bridge. For an example of wind reinforceing the fundamental frequency look up the Tacoma Narrows Bridge.

I have uploaded an accompanying photo of Ambleside's Bridge House; essentially a covered bridge.
Some bridge houses are merely built alongside a bridge and act as place to house guards for the bridge.
Nautically speaking, a bridge house is a housing that is raised above top deck level, from which navigation orders may be directed.
