The invention discloses a road network level bridge and tunnel maintenance method and device and a storage medium, and relates to the field of road network level road asset management. The method comprises the steps of calculating an initial technical condition distribution matrix and a state transition probability matrix of bridges and tunnels in a target area road network according to historicaltechnical conditions of the bridges and tunnels in the target area road network; according to the initial technical condition distribution matrix, the state transition probability matrix and the correction matrix, calculating to obtain a target technical condition distribution matrix of a bridge and a tunnel in a target area road network in a preset year; and obtaining a maintenance demand schemeof the bridge and tunnel in the target area road network in a preset year, and maintaining the bridge and tunnel in the target area road network according to the maintenance demand scheme and the target technical condition di
