|June 2011 (38.414 Degrees, 141.141 Degrees) Naruse Arch Bridge|
The Naruse Okumatsushima Bridge carries the Sanriku Expressway over the Yoshida and Naruse Rivers. The bridge includes a tied arch segment between the two river spans. The arch appears to be slightly kinked, it is tied to the closer pier with a steel cable, but this is apparently a design or construction problem.
When I first saw this bridge during a recent trip around Miyagi Prefecture I assumed the tilt to the arch was due to the earthquake. However, three or four different engineers assured me that this bridge has always been this way. I guess that a twisted arch is just as stable as a symmetric arch but it does seem odd.
