ambulanceA truck driver crushed by a bundle of rebar on Monday was the second worker killed at the construction site for the new San Francisco 49ers stadium.

Sports Illustrated (SI) is reporting that 60-year-old Edward Erving Lake II, was severely injured by the rebar, which was being unloaded from his truck. He died at a local hospital. Lake was reportedly an employee of Gerdau Ameristeel's Napa Reinforcing Steel facility, a subcontractor working on Levi Stadium

In June, 63-year-old elevator mechanic Donald White was killed at the site when he was struck by a counterweight while working in a shaft. OSHA is investigating the accident.

Construction on the $1.2 billion stadium which will replace Candlestick Park is expected to be completed in July, “and crews have been working in high gear to meet that deadline,” according to SI. “Officials say the accelerated work plan involves a highly coordinated scheme to maximize efficiency and avoid delays.”

The 68,500-capacity stadium will host the 50th Super Bowl in 2016.
