Over the past decade, Bangkok’s infrastructure and transportation network has developed extensively, with effective Skytrain and subway mass-transit systems.
But what the city lacks is the linkage between these systems and connections to release the pedestrian flow. One way to overcome this lack would be a system of elevated and underpass walkways, such as that that exists in other major cities such as Hong kong. A well-planned, elevated walkway system centred on mass-transit stations should be built in Bangkok’s central business district to seamlessly interconnect major shopping malls, office buildings and key tourist attractions.
Aside from the convenience and benefit of easing traffic jams, a system of elevated walkways would have a direct impact on real estate by affecting rents. In a typical retail centre, ground-floor rents are maximised due to access, but with direct access to higher floors, rents would grow in line with increased bypassing traffic. Similarly, office buildings with connected walkways would have ease of access and direct connectivity to mass-transit stations, which in turn would attract higher rents.
Beyond the real-estate benefits, a well-implemented system would provide ease of navigation for tourists. With clear signage and systemised walkways, tourists could easily navigate their way through the city by foot, and key attractions within the city could be promoted for sightseers.
Pedestrian safety and the quality of the pedestrian environment would improve, which would probably encourage walking and the use of mass-transit services, reducing the present traffic conditions. It would also bring lifestyle changes to Bangkok people, such as how they get to work and where they shop.
The key to implementation of such a system is to make it “seamless”, with cooperation from landlords and the authorities. Whilst Bangkok has attempted something like it at the Rajprasong Skywalk, and some office bildings are connected by foot-bridges to Skytrain stations, these are not enough to create an impact or deliver any benefits, and fall short of the properly planned and executed systems that can be found elsewhere.
Hong Kong provides a good example of an effective elevated walkway in terms of route planning, design and execution. Dating back to the 1980s, it was planned and built in several phases by the government in conjunction with developers such as Hongkong Land. The system effectively connects underground stations to major retail entres, offices and hotels and features escalators, moving walkways and staircases for access.
In Bangkok, such a system should be planned by taking into consideration the appropriateness of the route and design of the walkway. For example, the Rajprasong area should be connected throughout by covered elevated walkways from MBK into Siam Discovery, Siam Paragon, Central World and Gaysorn and from Central World to Platinum and the back of Siam Paragon. The Sathorn-Narathiwas intersection up to the Silom-Dusit Thani intersection is another area that should be considered. Existing walkways are partly old narrow footbridges without roofing and partly new, but built at different levels.
Design is an important issue, both in terms of aesthetics and functionality. To ensure maximum benefits for developers, landlords and individual retailers, the walkways also need to cut through office buildings and retail areas, and not bypass them with a single entry and exit points.
The project needs to be viewed as an overall scheme to derive an effective system. If not, we will end up with a series of disconnected projects. The most challenging aspect will be to amend the planning regulations and execute the project under one roof-that of the Bangkok Metropolitan Administration-with one centralised budget and full participation from public and private organisations.
It may be a far sighted dream for Bangkok, but I believe the benefits would be more certain than those from some other systems that require higher budgets but are not compatible with the city-such as bus rapid transit (BRT)!
