BREAKING THE BARRIER, Island Eastern Corridor (東區走廊), Hong Kong
In Canada, there has long been a debate of tearing down the elevated Gardiner Expressway in Toronto waterfront. Maintaining the deteriorating and somewhat underused infrastructure has become a burden for the city. As the trend of urban sprawl reversed in recent two decades, land in downtown Toronto, especially along the waterfront of Lake Ontario, has become precious asset for the city. Since 1960’s, the Gardiner has been a prominent barrier that cut off the city from its waterfront. The uninviting wasteland underneath the expressway has prevented most pedestrians walking to the waterfront especially at night. Since 1990’s, studies have been made for replacing the expressway, such as turning it into a tunnel or an urban park like the Highline in New York. Despite all the studies and debates, most of the Gardiner Expressway still remains in Toronto waterfront today. On confronting an aging waterfront expressway that hinders urban development and pedestrian connection, Toronto wasn’t alone. Negative aspects of these waterfront expressway are quite universal: poor waterfront access, wasteland below the structure, discontinued harbourfront, undesirable air ventilation, unattractive streetscape, high maintenance cost, etc. Since 1990’s, a wave of waterfront revitalization projects and demolition of elevated expressways have sprung up across the globe. Double decker Embarcadero Freeway in San Francisco was torn down in 1991, and so did Rio de Janerio’s Perimetral Elevated Highway in 2014, and Seattle’s Alaskan Way Viaduct in 2019.
In Hong Kong, sections of elevated expressways flank the Victoria Harbour in Western Kowloon and Eastern Hong Kong Island. The idea of building an expressway in Eastern Hong Kong Island was brought out in 1968 to tackle the traffic problems of King’s Road. It wasn’t until 1980’s that an elevated expressway, namely Island Eastern Corridor (東區走廊), was erected between Causeway Bay at the centre of Hong Kong Island and Chai Wan (柴灣) at the eastern end. The expressway includes a viaduct along the harbour between Causeway Bay (銅鑼灣) and Quarry Bay (鰂魚涌), passing by North Point (北角) along the way. East of Quarry Bay, the expressway shifts slightly inland from the coast, leaving a strip of waterfront promenade between Quarry Bay and Shau Kei Wan (筲箕灣). Designating the waterfront for public enjoyment was never the top priority in the 1980’s. From Causeway Bay to Quarry Bay, there are only a few boat landings and viaduct pillar supports where the public can walk out to have a peek of the harbour. In 2008, the authority proposed to construct a waterfront promenade between Causeway Bay Typhoon Shelter and Shau Kei Wan. In the past decade, stretches of waterfront promenades have been built to connect the harbourfront from Central to Causeway Bay, up to East Coast Park Precinct. East of Causeway Bay however, the waterfront promenades remain fragmented. After years of speculations, boardwalk constructions under the expressway have finally commenced in North Point. If the works can really deliver a continuous walkway below Island Eastern Corridor, then sooner or later we can walk along the north coast of Hong Kong Island all the way from Central Pier to Aldrich Bay Promenade (愛秩序灣海濱花園) in Shau Kei Wan, via a 9.5km pedestrian path. Then the barrier that separates the harbour from Eastern Hong Kong Island would finally be broken.
