The 40-ft cylinder in the picture is used to cut a hole beneath the bridge at South 250th Street and 16th Avenue South in Des Moines to place rebar for a cement footing to support the bridge. The project is slated to continue through the end of the year and into next year. Additional information can be obtained online at http://www.desmoineswa.gov/dept/pub_works/pdf/NT_Bridge_Photos.pdf
