preposition description

Between the barriers a lone car sits, enclosed by the glum fog, waiting patiently for the light to turn green. Beneath the bridge a cold grey river surrounds the remenants of the once inhabited city. Above, lost in the clouds a single pig flies upon the building searching for any sign of life. On the bridge guards await the unknown, prepared for battle. Within the building dust coats the lifeless factory, untouched since the war.
