Infrastructure development has the potential to have an important influence on various aspects of regional development. One important piece of infrastructure is a bridge. This study aims to analyze the influence of the construction of the Ocarina - Bengkong Bridge on economic and social aspects in Bengkong sub-district. This research uses quantitative methods by distributing questionnaires to the community around the Bengkong bridge. In the economic aspect, the research results show that the construction of the bridge has made a positive contribution to economic growth in Bengkong sub-district. The availability of better accessibility between Ocarina and Bengkong has increased population mobility, enabled the growth of the trade sector, and supported the development of the tourism sector in the region. Apart from that, the construction of the bridge also triggers an increase in property values and investment around the area.

Better mobility increases social connectivity between regions, facilitates cultural exchange, and strengthens community integration.
