Frequently Asked Questions
Find answers to common questions about the TKO Tunnel to Lam Tin
What is the TKO Tunnel to Lam Tin?
The TKO Tunnel to Lam Tin (TKO-LLT) is a major infrastructure project that provides a direct underground connection between Tseung Kwan O and Lam Tin. The 4.2-kilometer dual-bore tunnel significantly reduces travel time and improves connectivity between these two important areas.
When will the tunnel be completed?
The TKO Tunnel is scheduled to open in 2028. Construction began in 2024 and is progressing according to schedule. Regular updates on construction progress are available on our project progress page.
How much will it cost to use the tunnel?
Toll rates are currently under review and will be announced closer to the opening date. The pricing structure will be competitive and designed to encourage usage while supporting tunnel maintenance and operations.
What are the expected travel time savings?
The tunnel will reduce travel time by up to 60%. Current journey times of 25-35 minutes during peak hours will be reduced to approximately 8-12 minutes, providing significant time savings for daily commuters.
What types of vehicles can use the tunnel?
The tunnel is designed for cars, buses, trucks, and commercial vehicles up to 4.5 meters in height. Motorcycles and bicycles are prohibited for safety reasons. Vehicles carrying hazardous materials require special permits.
What are the operating hours?
The tunnel will operate 24 hours a day, 7 days a week. However, brief closures may occur during scheduled maintenance, typically during low-traffic periods between 2:00 AM and 5:00 AM on Sundays.
How do I pay the toll?
The tunnel will feature electronic toll collection systems supporting Octopus cards, Autotoll, and other electronic payment methods. Cash payment options will also be available at toll booths.
Are there any vehicle restrictions?
Yes, vehicles must not exceed 4.5 meters in height. Oversize vehicles require special permits and escort arrangements. Vehicles carrying dangerous goods must follow specific protocols and obtain advance approval.
What safety features does the tunnel have?
The tunnel includes comprehensive safety systems: emergency telephones every 100m, cross-passages every 250m, advanced fire detection and suppression systems, 24/7 CCTV monitoring, and emergency ventilation systems.
What should I do in case of an emergency?
In an emergency: turn on hazard lights, move to the emergency lane if possible, exit your vehicle and go to the nearest emergency walkway, use emergency telephones to contact the control center, and follow instructions from emergency personnel.
How is air quality maintained in the tunnel?
The tunnel features advanced ventilation systems with jet fans for air circulation and pollutant removal. Air quality is continuously monitored for CO, NO2, and visibility levels, with automatic adjustments to maintain safe conditions.
Is the tunnel monitored 24/7?
Yes, the tunnel control center operates 24/7 with trained personnel monitoring all systems. CCTV cameras provide complete coverage, and automatic incident detection systems alert operators to any issues immediately.
How long is the tunnel?
The tunnel is approximately 4.2 kilometers long, featuring dual bores with three lanes in each direction. It reaches a maximum depth of 60 meters below sea level.
What construction method was used?
The tunnel was constructed using Tunnel Boring Machines (TBM) with advanced ground monitoring systems. This method minimizes surface disruption while ensuring precise excavation and immediate tunnel lining installation.
What is the speed limit in the tunnel?
The maximum speed limit in the tunnel is 80 km/h. Variable speed limits may be implemented during peak hours or adverse conditions to maintain optimal traffic flow and safety.
How is the tunnel waterproofed?
The tunnel features a comprehensive waterproofing system including waterproof membrane systems, reinforced concrete lining, and advanced drainage systems to handle groundwater and prevent water ingress.
