On April 28, 2021 (Wednesday), the Incheon Free Economic Zone Authority (IFEZ) signed a win-win cooperation agreement at G-Tower to expand the participation of local construction companies in the Cheongna Sky Bridge (Third Link Bridge) construction project. The event also featured a networking session between bidders and local companies. Through this agreement, local companies with strong technical capabilities are expected to have greater opportunities to be reflected in design proposals and registered as partner contractors, thereby increasing the participation of local firms. The Cheongna Sky Bridge project is being carried out using a design-build proposal bidding method, with completion targeted for 2025.
