The invention provides an underpass expressway channel traffic keeping device and a construction method.The underpass expressway channel traffic keeping device is characterized in that traffic keeping trestles are arranged on the two sides of an expressway, two adjacent channel arch boxes are arranged at the bottoms of the traffic keeping trestles, and the two adjacent channel arch boxes at the bottoms of the traffic keeping trestles are connected in the mode that long bolts penetrate through the traffic keeping trestles; and the two pairs of channel arch boxes at the bottoms of the communication-keeping trestles on the two sides are communicated with each other. By building the unobstructed trestle, a complete working face is provided for channel construction, and construction quality control is facilitated; the construction method of the unobstructed trestle is mature, the construction progress is accelerated, the construction difficulty is reduced, and the safety risk is reduced; and meanwhile, the unobstr
