We would like to bring to your kind notice that the vertical clearance of the constructedPedestrian Underpasses at Km 36+550(LHS),78+336 (Both sides) and 82+475(Both sides)were with 2.S0m ONLY. These structures were completed prior to 27 Aug 2012, when theIndependent engineer was mobilized to site. We would like to put on record that theseunderpasses do not conform to the condition that the minimum vertical clearance shouldbe 3.50m as per NHAI's Circular No. NHAI/2008/Road Safety/IRF/588 dated 12.07 .201~(enclosing MoRT&H Circular No. RW/NH-35072/04/2004-S&R(R)dated 27.04.2010),"Ensuring Road safety - Engineering Measures". The Circular is enclosed for your referenceand records. .

In view of the above, you are requested to please take appropriate action for incorporation ofEngineering Measures mentioned in the above sited Circular.

Yours truly,
