At night, a crew of about four workers are performing road maintenance using a heavy asphalt milling machine. The machine is in the process of removing asphalt from the road surface and depositing the material into a truck. The workers are using shovels to clean up the excess milled asphalt along the curb. The work is taking place in an urban area near a grassy parkway. The location is lit with street lights and the machine's own working lights.
