was the first application of a commercialized earthquake early warning system (EEWS) to protect critical infrastructure in North America. Capable of detecting earthquakes with seconds to minutes of warning time the installation on George Massey Tunnel is designed to close the gates at either end of the tunnel so that no one can enter if a dangerous quake is inbound, and those already inside can exit as normal before shaking begins. The tunnel was constructed for the British Columbia Toll Highways and Bridge Authority, and is now administered by the British Columbia Ministry of Transportation. It has not had a toll on it since the 1960s, when tolls were removed from all of the bridges and tunnels in the Lower Mainland. The initial toll was 25 cents; on March 31, 1964, George Massey became the last person to pay the toll, which was then $1. Non-motorized tunnel use The tunnel is illegal for cyclists or pedestrians to traverse. A limited fare-free shuttle service is available year-round, during certain hours, and can carry tandems. Cyclists must wait at prescribed pickup points, but the van will make more than one trip if there are more than seven bicycles. Translink also provides year-round regular bus service through the tunnel with standard two-bike carrying racks. However, the lack of sufficient rack space translates to long waits for cyclists during peak hours. Cycling advocates have long advocated for improvement to this facility, as it is a major choke point limiting Vancouver-to-Tsawwassen Ferry bicycle traffic. Progress was made in June 2022 with the introduction of a "Bike Bus" route operated by TransLink. The bus had space for 9 bicycles and operated between late June until Labour Day on a route connecting Tsawwassen ferry terminal and Bridgeport station. Height limit The tunnel has a posted height limit of in both directions. The replacement bridge, which was to be constructed starting in 2017, would have likely eliminated the current height restrictions for over-height vehicles in the tunnel. Replacement On February 16, 2006, it was reported that the provincial government had plans to expand the tunnel's capacity, from four lanes to six, dubbed the "H99" project. On September 28, 2012, Premier Christy Clark announced plans to replace the aging tunnel within 10 years, addressing the congestion and safety issues currently plaguing the structure. On November 21, 2012, it was announced that the Ministry of Transportation and Infrastructure is leading
