The
first of its type in India, this eight-lane tunnel features two parallel tubes,
with four lanes each. The tunnel’s overall length is 4.9 km, of which 3.3 km is
underground and the remaining 1.6 km is being built using the cut-and-cover
technique.
The excavation for Tube-1 of the tunnel, connecting Kota to Chechat, has been
completed. Around 60 meters (m) of excavation remains for Tube-2 (Chechat to
Kota). This is expected to be completed within a month. Furthermore, the entire
excavation process is expected to be completed by June 2024.
The width of both tunnel tubes will
be expanded. The height will be increased from 8 m to 11 m, while the width
will be increased from 9 m to 19 m.
The
tunnel will also feature complex technologies such as sensors, light, pollution
control, data collecting, supervisory control, data acquisition and AI-based
monitoring.
The estimated completion timeline for the
tunnel project is December 2025.
