Monday night marked the beginning of nighttime trash collection for Jersey City. Crews began collecting trash as early as 11p.m. and were off the streets by the morning rush. For many residents it may seem trash had always been collected at night. However, most trash collecting was a very early morning activity. With the population expansion in recent years, sanitation crews were causing traffic snarls as the trucks blocked the streets during the daybreak hours. In an effort to reduce traffic congestion, trash and recyclable materials will be collected during the late night hours.
