The serviceability of upper structures of the Sangsang River Bridge during the designed period has decreased due to several factors such as environmental influences affecting the physical condition of the bridge, as well as the load that exceeds the designed capacity. Sangsang River Bridge needs to be maintained during the serviceability period in order to function optimally, safely and comfortably. The maintenance of the bridge begins with the examination of the existing condition of the bridge by utilizing Non-Destructive Test method using UPV Pundit PLLink 500 Digital tool. The data collected was then analysed to find out the serviceability of bridge structure. The analysed results showed that the value of concrete slab density was 17.8 MPa and of the concrete girder was 18.1 MPa. This values were classified as a deficient criterion and therefore the serviceability needs to be increased. Recommendations for enhancing the bridge serviceability was strengthening using Fibre Reinforced Polymer (FRP). Using 2 Layer SEH-51A or equivalent 2 Layer of E-glass fibre was suggested for concrete slab, meanwhile the use of 2 Layer SCH-41 or equal to 2 Layer Carbon fibre was suggested for concrete girder.
