The Ten Mile Road Bridge crossing I-84 in Meridian, Idaho was determined to be inadequate. A new interchange capable of accommodating traffic volumes through 2030 has been proposed. We will demonstrate through computer modeling that a Single Point Urban Interchange (SPUI) configuration is a safe and effective interchange option for managing the Ten Mile Road configuration. Design of the Single Point Urban Interchange (SPUI) will include a new six lane, composite, simple span bridge with four ramps converging on a single traffic control point. The bridge design is composed of two simple spans supported by piers and abutments. Reinforced concrete supported by steel girders will comprise the bridge deck. The foundations, retaining walls, and embankments will be designed. A stormwater management system will be incorporated with retention ponds for handling site runoff. All design will be completed in accordance with proper codes and requisite permits.
