The Eshima Ohashi Bridge (Japanese: 江島大橋, Hepburn: Eshima Ōhashi) is a rigid-frame bridge in Japan that connects Matsue, Shimane Prefecture, and Sakaiminato, Tottori Prefecture, over Nakaumi lake. It was built from 1997 to 2004, and it is the largest rigid-frame bridge in Japan and the third largest in the world. Images of the bridge have been widely circulated on the internet, owing to its seemingly steep nature when photographed from a distance with a telephoto lens, but in actuality, it has a less pronounced, 6.1% gradient in the side of Shimane and a 5.1% gradient in the side of Tottori.

Eshima Ohashi Bridge replaced the previous drawbridge, since traffic was obstructed often by ships for about 7 to 8 minutes, only vehicles under 14 tons were allowed and only 4000 vehicles could cross it per day.

The structure is a prestressed concrete (PC) five-span continuous hinged rigid-frame box girder bridge. To ensure smooth passage of ships under the girder, and for construction and earthquake resistance reasons, the bridge has a gradient of 6.1% on the Shimane side and 5.1% on the Tottori side, rising to a height of 44.7 m. With a central span of 250 m, it is the second longest girder bridge in Japan as of 2014, the longest concrete bridge in Japan, and the third longest PC rigid-frame bridge in the world.

Previously, a road bridge built over the Nakaura Water Gate, located just to the south, connected Sakaiminato with Eshima, which could only be reached by boat until then, and was used by approximately 14,000 vehicles daily. However, because the area over the lock was built as a drawbridge, traffic was cut off for about 7–8 minutes when ships passed, creating a traffic hurdle, and large vehicles over 14 tons could not pass through. Therefore, Eshima Ohashi Bridge was built to solve the traffic problems at Nakaura Water Gate. In conjunction with this, work to remove Nakaura Water Gate began around October 2005, and was nearly completed in March 2009.
