The opening of the Central Kowloon Route’s Yau Ma Tei section marks the completion of a tunnel, but it represents much more: a long-awaited release of pressure from the congested traffic structure in Kowloon. This project is not about speed; rather, it is a fundamental infrastructure initiative aimed at diverting traffic from the surface and redistributing urban space. Though it has taken time, it is progressing in the right direction.
This road was not a spur-of-the-moment decision. The concept of the Central Kowloon Route emerged as early as the 1990s, receiving official approval in 2016 and commencing construction in 2017. Its purpose has always been clear: to serve as a core component of Route 6, connecting Yau Ma Tei, Kai Tak, and Kwun Tong, with future links to Tseung Kwan O. The goal is not merely to alleviate congestion on a single road but to address the structural issues stemming from Kowloon’s long-term reliance on surface roads that interfere with one another.
The true test of engineering capability lies in the Yau Ma Tei section. The tunnel runs beneath a densely populated old district, with residential buildings, major roads, and public facilities above, including the vital Queen Elizabeth Hospital. To avoid impacting the hospital’s sensitive equipment and patient safety, certain blasting operations were strictly limited to designated time slots, with actual operational windows lasting only about 15 minutes. This is not a matter of inefficiency but a reflection of urban realities, where public safety must take precedence over expediency.
Simultaneously, the tunnel had to avoid the MTR structures, with some sections dangerously close to active railways, precluding conventional blasting techniques. Instead, low-vibration, slow methods were employed. This meant that progress could not be hastened by simply adding more workers or shifts; it relied on meticulous planning and disciplined execution.
The surface works were equally challenging. To accommodate the tunnel’s alignment and road restructuring, the multi-storey car park building in Yau Ma Tei, which spans the road and integrates with elevated roads, needed to be demolished. Such old layered infrastructure, once construction begins, triggers a chain reaction affecting not just a single building but also traffic rerouting, structural resets, and community adaptation. Completing this without causing long-term chaos reflects a high level of engineering management maturity.
In terms of outcomes, the opening of this section deserves positive recognition. The Yau Ma Tei section is set to open by the end of 2025, without major safety incidents or catastrophic delays, which is commendable. Regarding costs, the government has yet to release final audit figures, but overall expenses remain broadly within the original estimates, showing no signs of structural overspending.
Of course, this does not mean that Route 6 is complete. The remaining sections connecting Kai Tak, Kwun Tong, and Tseung Kwan O are still under construction, and the full benefits of the corridor will only be realized once it is entirely connected. However, the completion of the Yau Ma Tei section at least proves that the most difficult and error-prone segment has been successfully navigated.
Hong Kong has long been criticized for its slow and expensive infrastructure projects, but the issues often lie not in technology but in trade-offs. The Central Kowloon Route’s Yau Ma Tei section demonstrates that with clear objectives and a willingness to tackle the most challenging aspects, infrastructure can still serve as a tool for repairing urban structures. This opening is not the end but rather a turning point towards the completion of Route 6.
