The Cement Masons

Union cement masons will be engaged whenever concrete is poured, placed, finished or repaired on the new East span. These skilled craftworkers also perform concrete finishing of the precast segments of the Skyway road deck.

Cement masons working on the East Span are members of the Operative Plasterers' and Cement Masons' International Association, Local 300, headquartered in San Jose. OPCMIA members are the proud carriers of a tradition that predates the Pharaoh's pyramids. As early as man was building shelter for himself, there was plastering - first with mud or clay and later with a lime mixture much like that used in present times.

Today, bridges, canals, dams, reservoirs, roads and many other engineering feats would be impossible without the skills of OPCMIA cement masons. Together with the plasterers and fellow tradesmen, they have played a key role in shaping the world that surrounds us.
