Subway under Ground Zero reopens early

A STRETCH of New York's subway destroyed by the World Trade Center attacks is to reopen several months ahead of schedule.

Commissioning tests are currently under way and trains are due to start running again on 15th September, four days after the first anniversary of the atrocity and almost a year ahead of expectations.

The contract covered reconstruction of the 430m stretch of tunnel which carried subway lines 1 and 9 under the twin WTC towers. This was crushed under the weight of the structures when they collapsed on 11 September last year (NCE 13 September).

Joint venture contractor Tully/Pegno, whose $92M (£61.3M) bid was almost half the budgeted estimate, worked non-stop 24 hours a day seven days a week to complete the job.

Work was carried out along the edge of the WTC site and 'bathtub' foundation wall while recovery operations continued inside the site, and while new tiebacks and wall sections were built. The in-house design by New York City Transit kept to the original structural form dating from 1918, with the tunnel encased in concrete.
