90-degree downhill bend bridge

The so-called 90-degree bridge in Bhopal actually bends at 118–119 degrees, not a true right angle, and has sparked safety concerns and public controversy.

Overview

The bridge, located in Bhopal's Aishbagh area, became viral for its sharp bend, initially described as a 90-degree turn. However, an expert report from the Maulana Azad National Institute of Technology (MANIT) confirmed that the actual bend measures 118.4 degrees, closely matching the approved General Arrangement Drawing (GAD) for the project . The bridge was constructed under government supervision between 2021 and 2024, with the design revised in 2023-24 to accommodate site constraints .

Design and Construction Challenges

The bridge was intended to connect Mahamai Ka Bagh and New Bhopal, easing congestion for up to 300,000 daily commuters. Due to limited land space, proximity to railway tracks, and a nearby Metro line, the final layout included a sharp bend, which appeared abrupt in photographs and videos . The unusual curvature was not part of the original design but was incorporated during construction to navigate these constraints .

Safety and Public Reaction

The sharp bend raised serious safety concerns, particularly for two-wheelers and heavy vehicles, as navigating such a curve at speed can be hazardous . Images and videos of vehicles struggling to negotiate the turn went viral, leading to widespread public ridicule and trending hashtags like #BhopalBridge and #90DegreeTurn . The controversy prompted the suspension of seven engineers and the blacklisting of the construction firm M/s Puneet Chadha, although the firm argued that the bend was consistent with the approved design .

Legal and Administrative Actions

Following the expert report, the Madhya Pradesh government sought additional time to reconsider its decision to blacklist the construction firm. The High Court scheduled further hearings to review the matter, ensuring that all parties received copies of the technical report . The case highlights the importance of coordination between government agencies, proper planning, and public communication in infrastructure projects.

Key Takeaways

• The bridge is not a true 90-degree turn; it bends at 118–119 degrees.
• Sharp bends on bridges can pose significant safety risks, especially in high-traffic areas.
• Construction adjustments due to land and infrastructure constraints can lead to unconventional designs.
• Public scrutiny and legal oversight play a crucial role in ensuring accountability and safety in civil engineering projects. This bridge serves as a cautionary example of how engineering, urban planning, and public perception intersect in modern infrastructure projects.
