The drill rig operator spins the augur to clear the spoils brought up from drilling the shaft.
In the Salt River bottom, a drill rig uses a large augur bit to drill a shaft 110 feet deep. A column of rebar will then be lowered into the shaft which is then filled with concrete to construct a support pier for widening the westbound I-10 bridge.
At State Route 143, a worker breaks up concrete by dropping a steel weight on the pavement. Eventually new fly-over ramps will be constructed to connect SR 143 to I-10.
After changing the drill bit the operator places spoils into the bucket of a loader.
A worker ties rebar in the 30-foot column that will eventually be lifted by a crane and lowered into the drilled shaft. The shaft will be filled with concrete and form the foundation for widening the I-10 Salt River crossing.
A concrete pump fills the drilled shaft of what will become the foundation of a supporting pier for a widened I-10 bridge over the Salt River.
Near the I-10/US 60 interchange, a grader moves the soil in preparation for constructing the westbound Collector-Distributor (CD) road.
A piece of equipment called a scraper works with the grader in preparing the soil for CD road construction near the I-10/US 60 interchange.
Workers continue construction of the multiuse bridge at Alameda Drive in Tempe.
In the Salt River bottom, crews construct another rebar column for the widening of the Interstate 10 bridge.
A loader delivers fill material to crews constructing the south retaining wall of the northbound 48th Street bridge over Interstate 10.
Workers apply the finishing touch to a recently poured concrete slab for part of the new Broadway Road bridge over I-10.
Workers maneuver the concrete bucket into position over the concrete forms.
A bucket of concrete is raised to the workers who will pour it into the Mechanically Stabilized Earth (MSE) retaining wall that is part of a bridge that will eventually connect State Route 143 to I-10.
A roller compacts the soil on what will be the approach to the new Broadway Road bridge over I-10.
