The Diamond Bridge suspended across Dashbashi Canyon opened in 2021 as Georgia's first transparent walkway, engineered with 1,200 square metres of reinforced glass panels anchored to volcanic basalt cliffs formed 800,000 years ago.
The 240-metre span hovers 280 metres above the Khrami River, which carved this eight-kilometre gorge through successive eruptions of the Javakheti volcanic plateau. Soviet geologists mapped the canyon's layered tuff and ignimbrite in the 1970s, but the site remained inaccessible until Georgian investors commissioned the bridge from Italian structural engineers specializing in alpine suspension systems.
Dashbashi Canyon sits 110 kilometres southwest of Tbilisi in Tsalka Municipality, where the Khrami cuts through highland steppe at 1,400 metres elevation. The gorge holds endemic Caucasian flora — dwarf oak, Colchic boxwood, and wild cherry clinging to cliff ledges — alongside seasonal waterfalls fed by snowmelt from the Lesser Caucasus. The bridge itself weighs 42 tonnes, distributed across four steel cables embedded nine metres into bedrock. Walk paths extend beyond the glass section into forested canyon trails, passing stone ruins of medieval watchtowers that once monitored trade routes between Tbilisi and the Armenian highlands.
The diamond bridge Georgia from Tbilisi tours depart year-round, connecting the capital's Didube station to the canyon via paved highway through Tsalka's volcanic tablelands. Morning light enters the gorge from the east, illuminating the canyon's red-brown tuff walls and the Khrami's braided channels below. The site's name derives from the bridge's faceted steel supports, which refract sunlight into prismatic patterns across the glass deck. Conservation fees fund trail maintenance and endemic species monitoring conducted by Tbilisi State University's geology department.
Architectural documentation shows the bridge's deck panels measure 40 millimetres thick, laminated in five layers with polymer interlayers that distribute load across the span's three support towers. Engineers designed the structure to flex 15 centimetres laterally in high winds, common in the canyon's exposed position above the Javakheti plateau. The walkway opened after two years of construction and seismic testing, meeting European Union standards for public pedestrian infrastructure in seismically active zones.
