BROOKLYN - The MTA has released new video that highlights ongoing work to rebuild the Montague Tunnel after it was destroyed by Superstorm Sandy last year.

Officials say the repairs are being broken up into two phases, with the first focusing on the tracks, tube lighting, circuit breakers and substations. The second phase will fix signal equipment.

The tunnel, which connects Manhattan to Downtown Brooklyn, was shut down back in August, causing major disruptions to R train service.

The entire project is expected to last 14 months.
