You have reached the Stone Viaduct of the Children's Railway, carrying the narrow-gauge tracks across a rushing industrial spillway canal. Constructed between 1937 and 1938 from hand-hewn blocks of grey river basalt, this graceful railway bridge features three soaring semicircular arches spanning twenty-five meters. The architects skillfully integrated utilitarian hydraulic engineering with romantic landscape aesthetics, creating an eye-catching stone landmark that harmonizes perfectly with the rugged topography of the gorge.

Beneath the central arches of the viaduct, excess river water from an upstream hydroelectric bypass canal rushes down stepped stone cascades into a wide foaming basin before rejoining the main channel of the Hrazdan. The cascading water produces a cooling spray and a rhythmic roaring sound that echoes off the surrounding basalt cliffs. Beside the bridge, carved stone stairs lead to shaded observation terraces popular with local fishermen casting for river trout.

Building this railway viaduct in the late 1930s required immense physical labor from local master stonecutters, who chiseled each basalt voussoir by hand so the arches could support heavy locomotives during intense springtime floods. The stone has weathered nearly nine decades of mountain winters without showing a single structural fracture, standing as a testament to the timeless durability of Armenian stonework.

Standing beside the thundering cascade while looking up at the stone viaduct framed by weeping willows, one appreciates the thoughtful balance between industrial ambition and natural beauty that characterized mid-century Yerevan urban planning. The arched basalt viaduct stands as a noble example of harmonious Soviet Armenian engineering, gracefully bridging industrial water transport with the natural topography of the rugged canyon landscape. The soothing spray of water, the sturdy arches of hand-carved stone, and the gentle breeze sweeping through the canyon create a magnificent spot to admire both nature and human artistry.
