Work under way includes micropiling, reinforced cement concrete retaining walls, river training measures, rockfall barriers and hillside stabilisation systems aimed at reducing slope failure. Engineers presented technical measures and the sequencing of interventions to allow construction while keeping traffic moving. Attention was reported on improving drainage and benching to reduce hydrostatic pressure on slopes.
Tamta reviewed proposals for a 240-metre cut-and-cover tunnel included in the NH-10 upgradation programme to bypass a vulnerable stretch. Officials described the tunnel as a structural solution intended to improve safety and limit disruptions from landslides and severe weather. The scheme forms part of a package that combines hard engineering with road safety enhancements.
The projects are designed to strengthen connectivity across Sikkim and to provide reliable all-weather access for residents, tourists and transport operators. Complementary measures include signage, slope monitoring and targeted resurfacing to improve travel conditions. Coordination between central and state agencies was noted as essential for timely completion.
Officials said the works form part of broader efforts to modernise and secure the state road network and to support regional economic development. Funding allocations and tendering timelines were reviewed during the visit to ensure alignment with project milestones. Follow-up inspections were indicated to track progress and address emergent technical challenges.
