The Kurushima-Kaikyo Bridge system was the first in the world to implement a triple-suspension bridge design.
The strait beneath the bridge is famous for intense tidal currents that can reach speeds of up to 10 knots.
The bridge deck is engineered with a steel box-girder design to minimize vibration and structural sway from high winds.
Construction of the bridge foundations required the use of massive underwater caissons submerged at significant depths in the strait.
The bridge serves as a vital segment of the Shimanami Kaido, which is widely considered one of the premier cycling routes in Japan.
The 2nd Kurushima-Kaikyo Bridge is one of three interconnected suspension bridges forming the Kurushima-Kaikyo Bridge system, which spans the Kurushima Strait in Ehime Prefecture. Completed in 1999, this structure is a critical component of the Shimanami Kaido, a 60-kilometer road connecting Honshu and Shikoku via islands in the Seto Inland Sea. The entire three-bridge system spans a total length of 4,015 meters, making it one of the world's longest suspension bridge systems. It utilizes a continuous suspension design supported by massive steel towers anchored in the strait's strong tidal currents. The bridge features dedicated lanes for cyclists and pedestrians, isolated from motorized traffic by physical barriers. The deck height provides significant clearance for large container ships navigating the busy shipping lane below. Engineering features include wind-resistant stabilizers designed to withstand the region's frequent typhoon activity.
The observation areas at Itoyama Park offer the best elevated perspective of the bridge's suspension cables and the strait.
Use the dedicated cycling path rather than the motorized vehicle lanes for the best view of the strait.
Wear wind-resistant clothing, as the open expanse of the bridge is subject to constant, strong gusts.
Check local weather reports for high wind warnings, as cycling paths may be restricted during severe weather.
Do not attempt to walk or cycle the bridge during heavy rain or high-wind advisories.
Stay within the designated pedestrian and cycling lanes; do not stop in the middle of the path to block traffic.
