The newYichang-Wanzhou Railway crosses the northwestern part of the county, with two stations -Langping andHejiaping - located near the eponymous towns of the county.
TheChina National Highway 318, and the newly constructed Shanghai-Chongqing Expressway (G50) run roughly parallel to the railway. Building the expressway in this area required the construction of a number of tunnels and remarkable bridges, such as the Longtanhe Bridge just outside Langping Town.[8]
