阿賀浦橋, Concrete bridge in Agano, Japan.

The Agaura Bridge is a 942.4-meter, 14-span through Langer truss bridge on National Route 460, crossing the Agano River between Shimozato in Agano and Nakashinden in Akiha Ward, Niigata. It carries two traffic lanes and has a pedestrian walkway on each side. The current structure opened in 1958 and was extended to the east bank in 1976.

The bridge was first built as a wooden structure. Floods in 1947 washed away about 80 m of the bridge deck, prompting residents to campaign for a permanent replacement; the prefecture began construction, and the current bridge opened in 1958. It initially had a Langer girder section only on the west bank, and in 1976 the bridge section was extended to the east bank, completing its present form.

The name comes not from the river but from Agaura village, once on the west bank and absorbed into Niitsu town in 1925. The bridge carries National Route 460 across the Agano River between Shimosato in Agano and Nakashinden in Niigata's Akiha ward.

The bridge is easily accessible on foot and features broad, well-maintained pedestrian pathways that safely guide walkers across the river. Visitors should note that conditions can change with the weather, so planning your crossing time is helpful.

The bridge's name comes from Agaurа village, which was absorbed into Niitsu town in 1925 and no longer exists. The western end once met the Uetsu Line at a level crossing, abolished after an August 29, 1961 collision between a trailer and a water tower that killed two train drivers.
