New Jersey Governor Phil Murphy announced a new executive order that aims to further curb the spread of COVID-19 in the state.

The order will halt all non-essential construction in New Jersey beginning at 8 p.m. on Friday. For the past few weeks, while the majority of New Jerseyans were isolated at home, the state’s construction projects buzzed along.

New Jersey boasts some rather large construction projects, especially in Jersey City and Newark, which draw hundreds of workers every day. In addition to commuting, the workers often need to engage in activities where social distancing is impossible.

The new measures came during a press conference today where Murphy announced New Jersey saw its deadliest day yet of the pandemic.
