Usui 3rd Bridge 碓氷第三橋梁（めがね橋）
A bridge to a bygone era, now a nature trail
The nickname of this bridge is Meganebashi because the arches resemble spectacles (megane in Japanese).
In 1993, it was designated a National Important Cultural Asset
It is the largest arched brick bridge in Japan
How to Get There
With limited public transport, the easiest way to visit the Usui 3rd Bridge is by car.
Follow the Nakasendo Highway toward Karuizawa, and you'll see it just after Lake Usui . You can also take the Shinetsu Line from Takasaki to Yokokawa Station. From there it takes about one hour and 30 minutes on foot.
East meets West engineering
Your first impression may be that the bridge looks almost European in design, especially with the use of red bricks. In fact, it was built under the guidance of British engineer Charles Assheton Whately Pownall, becoming one of the first collaborations with non-Japanese engineers in the early Meiji era.
Nature hike over a former railway
In 2001, a six-kilometer nature trail was built along the disused railway lines and given the name Apt Road. Follow this path and you will understand what a feat it was to create such a pass, and appreciate the beautiful scenery that surrounds it.
