| Image # | Visual Focus | Engineering Insight | |--------|--------------|---------------------| | 1‑3 | (entrance and exit) framed by forested slopes | Shows alignment with minimal surface disturbance; portal design incorporates reinforced concrete arches with waterproof membranes. | | 4‑6 | TBM (Tunnel Boring Machine) launch – massive steel shield entering rock | Demonstrates use of a EPB (Earth Pressure Balance) TBM, suitable for mixed ground conditions (hard granites interspersed with laterite). | | 7‑9 | Segmental lining installation – precast concrete rings being hoisted into place | Highlights the “segmental lining” method, which allows rapid advance (≈ 12 m per day) while maintaining structural integrity. | | 10‑12 | Ventilation shafts – steel latticework with temporary scaffolding | Indicates planning for continuous airflow and emergency egress, essential for a tunnel longer than 5 km. | | 13‑15 | Geotechnical monitoring – sensors on rock faces, inclinometer readouts | Reveals an intensive instrumentation regime (piezoelectric stress meters, laser scanners) to detect ground movement. | | 16‑18 | Water ingress control – grouting rigs injecting polymeric sealants | Confirms that hydrogeological challenges (groundwater table > 2 m) are being mitigated with high‑performance grouting. | | 19‑21 | Construction workforce – diverse crews (engineers, masons, local labor) | Illustrates skill transfer and community involvement; many workers are from nearby villages, supporting local employment. | | 22‑24 | Safety drills – mock evacuation, fire‑suppression system testing | Shows compliance with National Tunnel Safety Standards (NTSS‑2022) , a prerequisite for eventual operational certification. | | 25‑27 | Environmental mitigation – temporary wildlife crossing, re‑vegetation of disturbed areas | Reflects the environmental management plan (EMP) required under the Western Ghats Conservation Act. | | 28‑30 | Progress markers – distance‑to‑target signage, digital dashboards | Provides a transparent project‑tracking dashboard for stakeholders and the public. | | 31‑33 | Night‑time illumination – LED floodlights on portal walls | Demonstrates energy‑efficient lighting that will later serve both construction crews and, eventually, tunnel users. | | 34‑36 | Finished tunnel cross‑section – clear view of the final lined tunnel, road deck under construction | Gives a preview of the operational geometry : a twin‑lane roadway with a 7.5 m internal clearance, provision for future rail‑track insertion. |

The word (ತುಲ್ಲು) in Kannada translates to “hole” or “cave”, and it is often used locally to describe natural or man‑made openings that cut through the landscape. In recent months a series of 36 newly released photographs of a little‑known tunnel system—colloquially called the Kannada Tullu Tunnel —has been making rounds among photography enthusiasts, heritage bloggers, and travelers who are curious about the hidden gems of Karnataka. kannada tullu tunne images 36 new
