The 2nd Avenue Cavern Plan

This article describes New York City’s Second Avenue Subway project which will run from 125th Street down the east side of the city to the Financial District. The project, the first major subway extension in more than 60 years, includes 13.7 kilometers of bored tunnels, sixteen subway stations, six cross-over caverns, and eight ventilation shafts and emergency exits. The project is divided into four phases. The article describes the type of rock that will be bored, fault zones, and areas of groundwater. It includes a discussion of cut and cover versus the shallow caverns construction methods, and the constraints imposed by the maze of sewer lines, power lines, water pipes, and steam lines.
