In our digital age, people are looking into blockchain tech to boost openness and faith in public processes. This includes government contract awards for road building where unfair methods, favouritism, and tampering often happen during bidding. Many setups using blockchain have been suggested to make contract awards clear and safe. But most of these plans end at giving out the contract and don't deal with what comes after. This later stage still has problems like poor money handling slow project progress, and little public insight. This research paper puts forward a system built on blockchain that manages clear and secure road tender allocation and offers transparency after the tender process. Our system logs every phase of the project on the blockchain, from when the tender is published to when bids are submitted, the winner is announced, and the project is carried out and finished. We also bring in smart contracts based on milestones and use storage that's spread out to make sure all reports proof of payments, and updates cannot be messed with and are open for everyone to see. This system allows government groups, people who check things, and the public to keep an eye on how things are going and how money is being used as it happens making road building open from the beginning to end.
