Usui Bridge (Japanese: 碓氷第三橋梁, うすいだいさんきょうりょう) is the largest brick-masonry arched bridge in Japan, located over Usui river in Gunma prefecture. The bridge was built in 1892 for Usui railway line to travel between Yokokawa in Gunma prefecture and Karuizawa in Nagano prefecture. It was designed by a British engineer Charles Assheton Whately Pownall during the Meiji era,[1] with some of the piers reaching heights of up to 110 feet (34 m).[2]

The total length is 91 meters (299 ft) and used about 2 million bricks for its construction. Following electrification of the Shin'etsu Main Line, a new line was constructed in 1963.[3]

In 2001, it formed a part of walkway trail.[1] [4]

The bridge is also called Megane bashi meaning spectacles bridge because of its arch shape. [5]
