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.
Workers have begun constructing the pier caps and support piers, known as the substructure, for a bridge that will connect I-10 and SR 143.
Workers construct the concrete forms for building a pier cap on top of the support pier for what will be a bridge connecting SR 143 and I-10.
Once the crane sets a girder, other crew members use a lift to set lumber between the girders that helps stabilize them.
A crane lifts a concrete girder off a truck for placement on the substructure of what will be part of a bridge connecting Interstate 10 and State Route 143. Each girder is more than 100 feet long and weighs about 88,000 pounds.
Crews slowly lowered the girder into position, guided by workers at either end.
