I-beam

Gamboa was placing an I-beam atop the plant’s paint building when he lost his balance and fell.

The center I-beam that ran the length of the house was twisted, and the two-by-four plate on top of it was only 7/8-inch thick due to being compressed.

The three then walked with dozens of others on a trail through the desert, crossed the Colorado River, and arrived at the I-beam barricades around 3 a.m.

Swain, 59, was a commercial electrician in Tampa when a collision with an I-beam on a construction site 10 years ago left him with severe neck and back injuries.

A side beam near the southbound lane showed a bent I-beam edge, which Cox said might have been hit by flying cargo Wednesday.
