Summary[edit]

Description
English: Construction of the East River Tunnels, 1909. Safety screen, extending from the roof downward into the tunnel, maintained within 100 ft. of the working face to maintain a chamber filled with compressed air along the tunnel roof in case of water ingress and give access to the emergency lock. The wooden runway extended from the safety screen to the bulkhead.
Deutsch: Bau der East River-Tunnel, 1909. Höchstens 30 m hinter der Ortsbrust wurde eine Schutzwand errichtet. Diese von der Decke nach unten in den Tunnel hineinragende Wand hätte im Falle eines Wassereinbruchs dafür gesorgt, dass zwischen der Wand und der Orstbrust eine Luftblase unter der Kalotte entstanden wäre, sodass den Arbeitern ein Fluchtweg zur Verfügung gestanden hätte. Mit dem unter dem Schirm hindruchführenden hölzernen Laufsteg links im Bild hätten sie die Notschleuse in der hinter der Ortsbrust liegenden Schottwand erreicht.
