Sir,

The failure of bridges can result from various factors, including design flaws, construction negligence, collapse from impact or explosions, flood-related failures, seismic activity, false work issues and scouring. Recently, a unique and concerning phenomenon has emerged in Mysuru, with peepal tree plants growing extensively on the Hinkal-Mysuru flyover, the city’s first flyover (as reported in SOM dated Nov. 29 titled “Over 90 peepal tree plants grow on city’s first flyover at Hinkal”).

In my analysis, this unusual growth can be attributed to inadequate compaction and the use of soil conducive to tree growth, exacerbated by a lack of maintenance. The potential risk involves the displacement of side slabs, posing a threat to the structural integrity of the flyover.

To address this issue, it is imperative to excavate and refill areas where peepal trees have taken root on the top layer, using high-quality soil and ensuring proper compaction. In instances where peepal trees have grown below the surface, careful removal, including roots, or the application of acid to prevent regrowth may be necessary.

Despite these precautions, continuous monitoring of areas affected by peepal tree growth is crucial. Additionally, accountability measures must be enforced against those responsible for the current state of affairs. The article also highlights the chaos caused by service roads, emphasising the need for prompt attention and resolution.
