The Karakoram Highway (KKH), also known as the Eighth Wonder of the World, is undergoing a massive transformation under the second phase of the China-Pakistan Economic Corridor (CPEC). As the primary land link between Pakistan and China, the modernization of this N-35 international route is essential for regional trade and energy security.
The focus has now shifted to the Thakot-Raikot Realignment project, a critical upgrade necessitated by massive hydroelectric developments in the region.
CPEC Phase 2: Transitioning to the Thakot-Raikot Realignment
In June 2024, during a high-level visit to Beijing by Prime Minister Shehbaz Sharif, both nations signed a formal framework agreement to expedite the KKH upgrade. This move signals a transition from CPEC Phase 1 (energy and basic infrastructure) to Phase 2 (industrialization and high-quality connectivity).
The centerpiece of this upgrade is the 250km Thakot-Raikot section. This part of the highway is being realigned to ensure that the transport of goods remains uninterrupted during the next decade of CPEC industrial growth. The realignment is not just a road improvement; it is a full-scale reconstruction of the high-altitude corridor.
Impact of the Diamer-Bhasha Dam on the N-35
The primary driver for the KKH realignment is the construction of the Diamer-Bhasha Dam. Once completed, the reservoir created by the dam will submerge several sections of the existing N-35.
To prevent a total disruption of the trade route, the National Highway Authority (NHA) and Chinese engineers have designed a new path that:
- Bypasses the projected reservoir levels.
- Utilizes advanced tunnel technology to navigate the steep Himalayan and Karakoram terrain.
- Includes high-load-bearing bridges capable of carrying heavy industrial machinery.
Year-Round Trade: The All-Weather Khunjerab Goal
Historically, the Khunjerab Pass has remained closed for four months during the winter due to heavy snowfall and extreme weather. However, the latest bilateral agreements have set a target to keep the border open 365 days a year.
Achieving all-weather connectivity requires the KKH upgrade to include:
- Anti-icing road surfaces in high-altitude zones.
- Construction of snow sheds to prevent avalanches from blocking traffic.
- Modernized customs and clearing facilities at the border that can operate in sub-zero temperatures.
Technical Specifications and NHA Design Updates
The NHA has finalized the technical design for the realignment, which involves significant engineering feats. The new KKH section will be built to international standards, accommodating an increase in heavy-duty logistics traffic.
Key technical highlights include:
- Wider Carriage Ways: Expansion to handle a higher volume of containers.
- Reduced Gradient: Realignment to make the climb easier for commercial trucks, improving fuel efficiency and safety.
- Advanced Monitoring: Integration of smart traffic management systems to monitor landslides and road conditions in real-time.
Economic and Regional Trade Impact
The KKH upgrade is more than just a domestic road project; it is a regional economic catalyst. By reducing the travel time between the deep-sea port of Gwadar and the Chinese land border, Pakistan aims to become a major transit hub for Central Asian Republics (CARs).
The upgrade is expected to:
- Lower Logistics Costs: More efficient routes mean cheaper transport for Pakistani agricultural exports.
- Boost Tourism: Improved road safety will open the Gilgit-Baltistan region to a higher volume of international and domestic tourists.
- Industrialization: The highway serves as the backbone for several Special Economic Zones (SEZs) planned under CPEC Phase 2.
Conclusion
The KKH upgrade project represents a strategic pivot toward sustainable and year-round trade between Pakistan and the global market. With the framework agreement for the Thakot-Raikot realignment now signed, the highway is set to reclaim its status as one of the most important trade corridors in Asia.
