The invention belongs to the technical field of wind power generation, and in particular, relates to a new energy expressway road wind power plant. The new energy expressway road wind power plant comprises bridge piers, a two-way expressway for separation driving arranged above the bridge piers, guardrails positioned on two sides of lanes of the expressway, and isolation strips positioned between the guardrails in middle of the expressway, wherein small drum type wind driven generators are arranged in the isolation strips; the small drum type wind driven generators in the isolation strips are arranged in two rows in a staggered manner; stand column type generator sets are arranged between the adjacent bridge piers; multiple small drum type wind driven generators are arranged in the transverse direction of the guardrails on the guardrails on the outermost side; all the small drum type wind driven generators are transversely placed; and the adjacent small drum type wind driven generators are connected end to end. The new energy expressway road wind power plant uses the landscape characteristics of the expressway for introducing the small drum type wind driven generators, effectively uses new energy, dose not pollute the environment and beautifies the road landscapes when generating electric energy, and is excellent in economic value and application prospect.
