Chao Phraya Sky Park
40,903 sf. Greenroof Bridge & Greenwall Planters
Greenroofs.com Featured Project January 20, 2023
We hope that your new year is off to a wonderful beginning, and we’re very pleased to be sharing the Chao Phraya Sky Park, an excellent example of adaptive reuse of a long-neglected city infrastructure. Keeping it interesting, the different levels of the vegetated bridge range from +0.5 to +4.5 meters from the structure and the plants and walkways are woven through the park.
Landscape architects LANDPROCESS, Kotchakorn Voraakhom and team who also designed the renown Thammasat University Urban Rooftop Farm (TURF), have contributed another important, successful, and beautiful project situated in Bangkok’s most significant historical area along the Chao Phraya River. Along with the architect and other designers, kudos to everyone’s persistence and fine work! And thank you to LANDPROCESS for once again sharing their video so we could include snippets into our own Featured Project Video.
Excerpt from the Greenroofs.com Project Profile:
Amidst the COVID-19 pandemic, the remarkable elevated public space, the Chao Phraya Sky Park (or CPSP), opened in 2020. Abandoned for almost 40 years, the halted infrastructure project was given a second life as the newest Bangkok landmark, and the nation’s first pedestrian bridge park spanning a river.
Designed by Urban Design Development Center, N7A Architects, and LANDPROCESS, the CPSP went from vacant to vibrant and its 360° view connects the city’s historic town and modern skyline.
In 1984, Thailand hoped to be the first nation to establish a sky train in Southeast Asia to carry commuters across the city’s main artery, the Chao Phraya River. But the project was cancelled shortly after completion of its structure, and Bangkokians named the abandoned infrastructure the “amputated bridge.”
In 2015, the Bangkok250 project was established for revitalization, led by the Department of City Planning and Urban Development, Bangkok Metropolitan Administration, Chula Unisearch, and the Urban Design Development Center, Chulalongkorn University. At one meeting, a community leader asked, “Why not put this useless bridge to good use, so our children can walk across the river to school?”
Located adjacent to the Memorial Bridge, a tribute to King Rama I, the founder of Bangkok, the CPSP emulates its curves in a contemporary manner. By merging two existing community parks across the river, CPSP becomes part of the 280-meter-long park’s connectivity on both ends. Squeezed between two sides of heavy traffic with just 8.5 meters of width, the designers split the linear park into two divided yet interweaving pathways to maximize space.
At the Sky Park’s midpoint, where the two divided pathways combine, a curved hilltop walkway is formed. Small cascading steps carve out sitting areas for a linear performance stage created for special events. The planting design consists of various low-maintenance plants—requiring less soil and having high resistance to wind and sun—with branches and forms that don’t widely spread and obstruct both roadways and driving viewpoints.
These native species promote urban biodiversity by providing a microclimate and green corridor for pollinators and insects. From the CPSP, pedestrians can enjoy views with the Memorial Bridge in the foreground, overlooking Bangkok’s postcard destinations like the Temple of Dawn, the Temple of the Reclining Buddha, and the Wichai Prasit Fort.
With a stunning panoramic vista of Bangkok over the River of the Kings, the vegetated Chao Phraya Sky Park provides a unique viewpoint from which to observe both the city’s past and present.
