As of March 8, 2026, the contractor has completed the installation of the crushing plant equipment and is now carrying out material testing before commencing large-scale crushing and screening of aggregates for project supply. Accordingly, the excavated soil and rock will be transported to two crushing and screening plants to create crushed stone aggregate for road embankment construction, roadbeds in tunnels, and as material for spraying concrete to reinforce the slopes and tunnel arches.
