What is the speed limit on all tunnel ramps and the HOS between B and C piers?

The speed limit on all tunnel ramps and the Highway of Service (HOS) between B and C piers is set at 15 km/h. This speed limit is in place primarily for safety reasons, as these areas can be congested and may have various types of vehicle and pedestrian traffic. Maintaining a lower speed helps ensure that drivers have sufficient reaction time to respond to any unexpected situations that may arise, such as people moving quickly or other vehicles changing paths.

Lower speed limits in these types of environments also contribute to reducing the risk of accidents and minimizing the severity of incidents should they occur. Additionally, enforcing a consistent speed limit helps regulate traffic flow and maintains overall safety for everyone in the vicinity, including airport staff and passengers.
