The antonym for the word "bore under" could be "build over" or "construct above". These words imply creating structures above the ground level rather than digging underground tunnels or pathways. Building over can include constructing roads, bridges, buildings, and other infrastructure without disturbing the underground surface or degrading the environment. Unlike boring under, building over involves directionality above ground, and it is a way of catering to the needs of modern urbanization. Building over also ensures that the ecological balance of the area remains intact, and natural habitats, wildlife, and water resources are preserved.
