New 2nd Ave Subway Exhibit Opens

Have you ever wondered about the construction techniques being used to build the Second Avenue subway?

Now you can learn more by visiting the MTA's Second Avenue Subway Community Information Center (CIC), which recently unveiled its new exhibit: En Route: The Techniques and Technologies Used to Build the Second Avenue Subway.

CIC Exhibit

The second of the CIC’s biannual exhibits uses interactive and static displays to demonstrate 13 of the construction technologies used to build the Second Avenue Subway.

Techniques such as tunnel boring, controlled blasting, cut and cover excavation, air scrubbers, and ground freezing are explained through photos, videos, and animations in an interactive exhibit using iPads to control wide screen displays.

An entire wall of the CIC displays a cross section of the project from 63rd Street to 104th Street to illustrate the bedrock profile under the surface and the techniques used to cut through it and excavate above it.

A virtual tour of the 86th Street cavern and tunnel is included in the new exhibit. Also part of the exhibit, the CIC showcases two new models: a replica of the tunnel boring machine and a scale model of the 96th Street station.

Want to learn more? Visit the CIC to see the exhibit first hand:

Mondays, Wednesdays and Fridays from 10 a.m. to 6 p.m.
Tuesdays and Thursdays from noon to 8 p.m.
2nd Saturday of each month from 11 a.m. to 3 p.m.

The CIC is located at 1628 Second Avenue, between 84th and 85th Streets.
The nearest subway stop is the 86th Street station on the 4/5/6 Lexington Avenue Line.
