This is an image of a covered bridge, a structure built to improve the lifespan of otherwise exposed timber bridge elements, which typically would only last a decade or so without cover. This example is the Fallasburg Bridge near Lowell, Michigan.

The description states:
FALLASBURG COVERED BRIDGE
In Kent County, a short distance north of Lowell, the Fallasburg Bridge crosses the Flat River. Still in use today, this is one of several covered bridges near Grand Rapids, Michigan.
–While they are no longer ideal for heavily used transportation routes, these bridges are maintained and renovated for their scenic and historical interest. This image likely dates from the 1950s.
