The Geosynthetic Reinforced SoilIntegrated Bridge System Technology (GRS-IBS) could reduce cost between twenty five to sixty percent and maybe more from conventional construction method. This report evaluated the cost and time between two bridge projects with comparable characteristics, one using GRS-IBS technology and the other using a conventional bridge construction method. Time and costs from each construction project was gather for analysis purposes. The time of construction using GRS-IBS technology represents a 14% of a total time spent for a conventional bridge construction method and the 21% of the total cost of a conventional construction method. Because this technology needs less equipment, different materials construction, less use of labor and can easily be constructed; provides more advantages than a conventional bridge construction method. Key Terms- Cost Reduction, Easily Fast Construction, Geosynthetic Reinforce Soil (GRS), Integrated Bridge System (IBS).
