You are looking at a part replica based on the Tien road bridge in OO Gauge with 2 piers, but could be used as a railway bridge.
Dimensions:
250mm L x 83.5mm W x 52mm H (bridge section)
72mm W x 25.8mm D x 57.5mm H (each pier)
Obviously the height from the ground to the bottom of the bridge would be 57.5mm
