Rebuilding & Improvements
Our Approach to the Rebuilding Process
The magnitude of the work needed in the Canarsie Tunnel is too great for a closure on nights and weekends only. That left us with two options for getting the work done: closing the entire tunnel for 18 months or running one track at a time for three years. A robust public outreach process was conducted to engage with and obtain input from community stakeholders — customers, business owners, and elected officials. Concurrently, we performed an internal assessment of the two options in terms of efficiency, alternative service, risk and other factors.
Based on the needs of the system and the impact to our customers, we decided that the best way to accomplish this critical work is to close both tubes in the tunnel beginning no sooner than 2019.
In March of this year we were pleased to announce that the closure period has been shortened from 18 to 15 months, due to contractual provisions included to expedite demolition, encourage acceleration of the tunnel work, deter delays, enable traffic mitigation work, and the testing and commissioning of systems.
The two-track closure option offers the following benefits over keeping one track open between Manhattan and Brooklyn:
Prior to the 2019 closure, preparatory work will be required, some of which will require weekend closures of the tunnel.

The wide scope of the rehabilitation project not only involves the tunnel, but also the stations near them, and three new power substations, which will allow us to increase line capacity by 10 percent.
Bedford Av station in Brooklyn and 1 Av station in Manhattan will receive significant accessibility and capacity upgrades.
