Laborers Local 309 • Rock Island, IL

Built on Strength. United in Work.

Our members are the skilled men and women who build the roads, bridges, schools, and hospitals that connect and strengthen our communities. From public infrastructure to private development, the work of Local 309 touches every corner of the region.

But we’re more than just builders.
