The Ministry of Transport and Communications announced on Apr. 29 that construction work on the ventilation shafts for Line 2 of the Lima and Callao Metro has made significant progress, with nineteen out of twenty-eight shafts now fully completed.
These ventilation shafts are essential for ensuring air circulation, removing smoke or gases, providing emergency exits, allowing natural light into tunnels, and regulating temperature. Of the nineteen finished shafts, four are part of Stage 1A which is already operational. The remaining fifteen belong mainly to Stage 1B and are currently undergoing architectural work such as wall finishes, roofing, flooring, windows, and enclosures.
According to the ministry’s update, seven of the nine remaining shafts in Stages 1B and 2 have surpassed ninety percent completion in civil works and have started architectural phases. The last two are nearly seventy percent complete in civil works. Additionally, nine ventilation shafts for Branch Line 4 show progress between eighty and ninety percent; only one shaft is about to begin construction.
The Ministry said these structures contribute to efficient railway operations. “The main function of a ventilation shaft is to guarantee fresh air circulation and evacuation of stale air or gases in underground tunnels,” according to the release. The Ministry also highlighted that “Line 2 will be Peru’s first underground train system with a length of twenty-seven kilometers and thirty-five stations including Branch Line 4.” This new metro line is expected to reduce travel time between Callao and Ate by approximately forty-five minutes compared with current public transport options.
