The laboratory was practically abandoned after HKU researchers completed their experiments, as no other experiments of a similar nature made further use of the facility. However, in 2006, HKU and the

. Due to the high amount of traffic through the tunnel, researchers only have access to the laboratory 3 to 4 times per week, mostly during late night and early morning hours. During these experiments, maintenance and cleaning operations within the tunnel have to be suspended, and all traffic is rerouted through one tunnel tube.
