Cross-city line, section 1

Ecological Site Su­per­vision

Section 1 of the cross-city line covers the Zurich main station track area from Altstetten to the Langstrasse underpass. Two bridges (Letzigraben and Kohlendreieck) are to be erected on the over 3 km long section. SBB places strong emphasis on environmentally acceptable construction methods under professional supervision in compliance with statutory environmental requirements and planning approval stipulations. The most crucial areas include:

  • Air pollution control for construction vehicles and equipment
  • Water protection, storage of water-polluting liquids
  • Excavation supervision and waste disposal management
  • Supervision of landscape planning
