Overhead Conveyor Belt Moves Concrete Over Moving Traffic

Workers have installed a conveyor belt over the eastbound lanes of Denver’s C-470 as part of an expansion project, moving nearly 150,000 square yards of concrete over highway traffic. The concrete is then dropped into trucks and fed to a giant paving machine.

The $276 million project will expand a stretch of the highway between I-25 and Wadsworth Boulevard.  

According to the Colorado Department of Transportation (CDOT), the belt over C-470 is the first of its kind in the state. Prior to the conveyor, trucks would have to carry cement across traffic lanes to deliver loads to the paving machine. This slowed, and sometimes even stopped traffic while raising the potential for accidents. With the new system, concrete moving through the conveyor is deposited to a center lane.

Free flowing public traffic will also help cut down on emissions and fuel consumption, CDOT officials said.

According to the Denver Post, the conveyor belt stretches 18 feet high, 16 feet wide, and 85 feet at length.
