Pengbu Bridge, Road-rail truss bridge over the Qiantang River in Hangzhou, China.

Pengbu Bridge is a 1,350.8-metre bridge over the Qiantang River between Shangcheng and Xiaoshan districts, 47 metres downstream of the old Pengbu Bridge. It is a catenary-stiffened continuous steel truss bridge with two levels: an eight-lane expressway on top and Hangzhou Metro Line 19 tracks plus a cycle and pedestrian path below. Its span arrangement is 72 + 122 + 4×240 + 122 + 72 metres.

Construction of the new Pengbu Bridge began on 31 May 2019, and its main structure was joined on 25 June 2021. The lower deck carrying Hangzhou Metro Line 19 opened on 22 September 2022, followed by the upper deck, the Airport Expressway, on 28 September 2022. It was built as part of the urban-section reconstruction of the Shanghai-Hangzhou-Ningbo Expressway, 47 metres downstream of the old Pengbu Bridge.

The bridge's design takes the waves of the Qiantang tide as its motif: the upper steel deck is a blue wave form, the lower truss a white lattice. It is the eleventh bridge over the Qiantang, hence the local name "Qianjiang Bridge No. 11".

The lower deck carries Line 19 of the Hangzhou Metro plus a walkway and cycle path, while the upper deck is the eight-lane Konggang Elevated Road, opened on 28 September 2022. The bridge stands 47 metres downstream of the old Pengbu Bridge, between Shangcheng and Xiaoshan districts. Pedestrians and cyclists use the lower level; the road deck is for motor traffic.

The bridge's 1,350.8 m span is arranged as 72 m + 122 m + 4×240 m + 122 m + 72 m, and it stands just 47 m downstream of the old Pengbu Bridge. It is described as China's first multi-span, long-unit road-rail continuous steel truss bridge with a catenary-shaped upper stiffening system.
