| 摘要： | Madam/Sir, The Two Laning Manual stipulates 2.5m wide paved shoulder and 1.5m wide earthen shoulder on either side of 7m wide carriageway. Accordingly, width of 2 lane bridge deck with footpath is 18m i.e., 7m (carriageway) + 2 × [2.5m (paved shoulder) + 0.5m (shyness) + 0.5m (steel crash barrier) + 1.5m (footpath) + 0.5m (New Jersey Crash Barrier)]. Ministry vide circular No. RW/NH-33044/22/2020-S&R(PaB) dated 17.07.2020. revised the width of paved shoulder and earthen shoulder in open country with isolated built-up area to 1.5m and 1.0m respectively. However, it is seen that in different 2 laning NH projects different deck width of bridges both with/without footpath are being adopted, which is not desirable. |
