This document summarizes the design and analysis of a river bridge deck slab located at Vangani-Karav-Pashane. The researchers designed a simple reinforced concrete deck slab using the working stress method and verified the results using STAAD.pro software. Key aspects of the design included considering IRC Class A loading, proposing a two-lane deck slab with a 6.8m carriageway width, and analyzing stresses, shear forces, and moments on the slab. Manual calculations were performed and compared to STAAD results. The design aimed to facilitate easy commuting across the Ulhas River by replacing a deteriorating existing bridge deck.
