About the project

As part of the project to construct the Red Line for Tel Aviv’s mass transit system, Gash designed a 5/8 drive shaft located between the Geha interchange and the Em Hamoshavot bridge. The drive shaft was designed to launch a pair of TBM tunnels and receive an NATM tunnel that penetrates the shaft at a very sharp angle. The shaft is approximately 28 m deep and has an area of about 2,000 sqm. The shaft was built in an environment with a high groundwater table.
