Generate for me a spooky scene outside a canyon with an arch, a bridge, and a serpentine creature.

An arch of pale stone straddles the crests of both crevice walls as their union approaches to the north, closing above a narrow tunnel that flickers in and out of vision in time with the wavering torchlight. The bridge above has been worked along its under-surface with the design of a serpentine creature, its blind eyes watching all who pass beneath its visage.
