Post-Sandy subway repairs are causing headaches for some commuters, but the now the Metropolitan Transportation Authority is giving the public a glimpse of the work being done in newly released video.
Since August, renovation work has taken place on the tunnel connecting part of Lower Manhattan and Downtown Brooklyn, causing riders of the R train to reroute their commutes.
The work is taking place in two parts -- one to repair tracks and power supplies, another to repair signal equipment.
One MTA worker who appears in the video says the overhaul is necessary.
"When Hurricane Sandy struck this entire section of the entire tunnel was flooded with sea water. The electrical cabinets you see behind me contained the signal equipment which control the motions of the trains, controls the fans in the tunnels, controls basically everything down here. It was all destroyed," said MTA Project Manager Jonathan Barnhart.
The repairs are expected to last until October of next year.
