The Metropolitan Transportation Authority (MTA) today announced critical infrastructure work coming to its 6 Av and 8 Av lines in Manhattan this summer. The track renewal project on the 6 Av Line includes replacement of the downtown express track at 47-50 Sts- Rockefeller Center. The existing track has reached the end of its useful life and requires complete replacement, which will lead to improved reliability and better service in one of the busiest corridors in the system. To minimize service changes and future outages the work will occur concurrently with the 8 Av Line Signal Modernization project.

The signal modernization work along the 8 Av Line  will include the installation of axle counter technology which will improve the availability of the new signal by replacing less reliable components of the legacy signal system. Track switch diagnostics that will predictively gauge the health of switch machine movement and remotely report potential failures will also be installed. Once completed, the modern Communications-Based Train Control (CBTC) system signaling system will be installed between 59 St-Columbus Circle in Manhattan and High St in Brooklyn, making that busy corridor more reliable for thousands of daily customers.

Weeknight work will start at approximately 9:45 p.m. Mondays through Thursdays and end at 5:00 a.m., Tuesdays through Fridays, starting Monday, June 14. Weekend work will begin on Friday, July 2 with work starting Fridays at 9:45 p.m. and concluding by 5:00 a.m. on Mondays.
