A class of children watch the large backhoe at work.

The curb was pulled up in big pieces. Here the large backhoe tilts with one track off the pavement as it pulls the concrete out of the ground.

Then the sidewalk is broken up.

Big pieces of sidewalk are broken into smaller pieces so that they fit into the bulldozer's scoop.

The bulldozer takes the concrete, dirt, and grass off to the dumptruck.
