A construction worker was killed at the Gilcrease Expressway expansion site in Tulsa, Okla., on August 16 when a piece of heavy equipment rolled down a steep hill and crushed him. Noe Mendoza, 45, an employee of Plains Bridge Contracting of Yukon, Okla., was found by emergency responders. Mendoza was hit by a 120,000-lb road spreader, with a big diesel-driven scraper to pick up pavement, and declared dead at the scene, says Bill French, spokesman for the Tulsa Fire Dept. Tulsa Police Dept. public information officer Leland Ashley said the machine that killed Medoza was a Caterpillar 621G wheel tractor-scraper.
