美原大橋, Cable-stayed bridge in Ebetsu, Japan

Mihara Bridge is a cable-stayed crossing spanning the Ishikari River and connecting the shores around Ebetsu. Two tall towers support a network of steel cables that suspend the roadway above the water.

Construction of the Mihara Bridge began in October 1995 and it opened on 26 March 2005 as part of the 3.9 km Mihara Bypass of National Route 337, a project costing 31.7 billion yen. The bypass cut about ten minutes from the trip between the Warabidaira district and the Ebetsu-Higashi interchange. A section of the Mihara road opened on 18 March 2009.

The bridge carries National Route 337's Mihara Bypass, opened on 26 March 2005, and its opening cut about ten minutes from the drive between the Warabidai district and Ebetsu-Higashi Interchange. Its 80 m main tower was lit at night and won the 2005 Lighting Popularization Award, excellent facility category, though lighting is currently suspended to save power.

The bridge has four traffic lanes for cars and wide walkways on both sides for pedestrians and cyclists. Anyone crossing on foot will find dedicated paths separated from vehicle traffic and can enjoy views of the river.

The bridge's 80-metre main tower was lit at night and received the 2005 Illumination Popularization Award (Excellent Facility Prize), but the lighting is currently suspended to save electricity. Its total construction cost was 31.7 billion yen.
