| The Shin-Minato Bridge is part of a 3.6-km-long port road connecting the eastern and western areas of the harbor entrance to the Toyama New Port. As the main bridge of the harbor road, the 600-m-long Shin-Minato Bridge possesses 127-m-high main masts and a central span of 360m. The bridge was designed as a double deck structure with bicycle and pedestrian access under the roadway. Concerning the bridge design, the A-form of the main masts and uniform white finish produce an attractive and sharp appearance that harmoniously blends with Tateyama Mountain Range in the distance. |

| Located about 2km from the mouth of the Yoshino River, the Awa Shirasagi Bridge is part of the Tokushima Outer Ring Road Project. This particular section of the construction involves the erection of the 575m superstructure comprised of the four-span continuous “Cable Egret” plate-girder bridge. A long span was used due to the presence of a tidal flat at the base of the bridge that serves as a habitat for rare species. As a measure to avoid obstructing the flight paths of birds, this bridge form was employed with its low height for the main masts and minimal amount of cable strands. |

| Fifty years since the construction of the Ondo Bridge, the Kegoya Ondo Bypass connecting Kegoya of the city of Kure with the town of Ondo is under construction in order to mitigate the increasing chronic traffic congestion of the Ondo Bridge. As a section of this bypass, the Second Ondo Bridge is located approximately 350m to the north of the Ondo Bridge. Once completed, with a total length of 292m and 280m between the arch supports, it will become the forth longest arch bridge in the nation. The largest domestic industrial-sized floating crane was used to construct the large block of the center span in a single section, requiring the adoption of an aerial joint construction. |
| 4.Sanagawa Bridge |
 |
| Central Nippon Expressway Company Limited Kajima Corporation |
| The Sanagawa Bridge in Aichi Prefecture has been constructed under a design-build contract for a package of substructure and superstructure. The Sanagawa Bridge is a 699m long 6-span continuous rigid frame PC box girder bridge with a main span of 142m long and a maximum pier height of 89m. High-strength rebar and concrete were used for the piers, and high-strength concrete with ordinary Portland cement was used for the superstructure for enhanced durability. A “Cut-Bamboo” type structure has been adopted for the construction of foundation to minimize environmental modifications. The considerations for durability and construction method made in this bridge that will contribute significantly to the development of future bridge technology deserve the Japan Society of Civil Engineers Tanaka award. |
