Hirakata Bridge, Steel bridge in Hirakata City, Osaka Prefecture, Japan

Hirakata Bridge (Hirakata Ōhashi) carries National Route 170 and Osaka prefectural routes 6 and 139 across the Yodo River, linking Ōtsuka-chō in Takatsuki with Sakura-machi in Hirakata. The current second-generation span is 689 m long with four lanes, two upstream completed in 1967 and two downstream in 1971. Immediately downstream stands the Hirakata water-supply pipe bridge.

Before the 1930s a ferry crossed the Yodo River near Hirakata-juku; no bridge had been recorded upstream of the O-kawa and Naka-tsu river fork since the Middle Ages. The first Hirakata Bridge opened on 10 October 1930, 694 m long and 6.64 m wide, with 15 reused straight-chord truss spans moved from Keihan Electric Railway's former Uji and Kizu river bridges and two newly built curved-chord trusses at the centre. The current bridge is the second: the upstream two lanes opened in 1967, the old span was removed, and the downstream side was added in 1971 for four lanes.

The name Hirakata comes from the former Hirakata-shuku, a post station on the Kyōkaidō near which a ferry crossed the Yodo before the first bridge opened in 1930. Today Keihan Bus routes linking Hirakata-shi Station with Ibaraki and Takatsuki cross the bridge frequently.

The bridge carries National Route 170 and Osaka prefectural routes 6 and 139, with four lanes after the 1971 downstream widening. At its southern end it meets Osaka Prefectural Route 13, the old National Route 1, so traffic between Kyoto and Osaka is heavy; Keihan buses run frequently across it between Hirakata, Takatsuki and Ibaraki. The downstream west side is immediately flanked by the Hirakata water pipe bridge.

The first Hirakata Bridge, completed on 10 October 1930, was 694 m long and 6.64 m wide; its 15 end spans were straight-chord trusses moved from Keihan Electric Railway's former Uji and Kizu river bridges, while two curved-chord trusses were newly built for the centre.
