National Highways Authority Of India [NHAI] — Obstruction on NH-16

The NH16 is the route from Kolkata towards Jamshedpur in Jharkhand, and beyond. On the Bengal side of the highway there are a number of metal structures which have been placed on the highway by the local residents and local police.
These are slowing down and obstructing the highway traffic. They are a menace to highway safety specially at night as there is no reflector attached to these metal structures which block 2 lanes out of 3 at many highway crossings.
Pls see the pictures attached which show the problem clearly.
Maybe the intent is to slow down the cars for safety reasons but actually the effect achieved is the exact opposite. Because these obstructions are a menace, and cars often collide with them at high speed causing needless accidents and Damages.

I believe these are not authorised by NHAI and just placed without any permission from anyone by local residents and/or local police.
It’s my sincere request to NHAI to act stringently against these obstructions and have them removed for safety of both pedestrians and vehicle travelers on highway
