The central span that crosses over the railway includes a precast concrete slab supported by steel beams, which acts as the formwork for a cast in-situ reinforced concrete slab on top. The main span is supported by piers, while the rest of the bridge sections are each supported by two bearings. The new bridge was designed using prestressed concrete slabs for the bridge spans, which vary in length from 15m to 27.5m. engineering consultants, is one of their first projects designed entirely in 3D using Allplan Bridge and exploits the benefits of parametric bridge design. The bridge, which was designed by Sagasta s.r.o. The new seven-span bridge will have a total length of nearly 145m, with a 27.5m span over the railway. Not only will this enable the separation of the road and railway traffic, but the existing road alignment could be improved at the same time to provide a safer and more comfortable ride. In keeping with the design of the latter post-war plywood invention in which all functions are housed in a single form, the Drift Bridge also incorporates the roadway, seating, and railings as one structure, so to speak.In Kynšperk nad Ohří in the Czech Republic, a new bridge will soon replace the existing level crossing. Another source of inspiration was the surrounding ranch-style homes as well as Eamesian leg braces.
Incidentally, the name of the small wood-steel hybrid bridge comes from its design concept, which in turn is based on the driftwood that accumulates in the bed of West Creek depending on seasonal water levels. Volkan Alkanoglu calls the interplay of prefabrication and rapid installation “plug-and-play urbanism” and an economical method for erecting medium-sized infrastructure structures – assuming accurate digital planning. Installation on site took just a few hours thanks to prefabrication. The 19-meter pedestrian bridge borrows from shipbuilding with a steel-reinforced substructure clad in CNC-cut and turn-milled wood planks. The fact that this has now changed may also have something to do with the way it was designed and built by architect Volkan Alkanoglu. At the point it now spans, there was traditionally no overpass and thus no way across the not-so-narrow creek for a length of seven apartment blocks. Since 2021, the shapely Drift Bridge in Fort Worth, Texas, has graced – and run across – West Creek.
The Drift Bridge in Fort Worth is not only extraordinarily beautiful, but also a successful example of economic plug-and-play urbanism.
