Part of the 12.824 km Package L2B-C101, the Shunya Bridge features an 80-meter main span, a 50-meter anchor span, and a prominent pylon (pier #478), where concrete was poured for its pile cap in October 2023.

Comprising 35 precast segments, each 12.9 meters wide, the bridge components are cast at a yard situated across from the Mumbai – Ahmedabad Bullet Train project’s BKC Station site, currently being constructed by HCC – MEIL JV.

The conceptualization of the Shunya Bridge in 2020 by MMRDA pays homage to the historic invention of ‘zero’ in India during the 5th century. The design of the bridge serves as a tribute to the profound significance of ‘zero’ in the technological world.
