R.W. Giertsen

In the 1950’s, Walter’s son, Richard W. Giertsen, took the helm of the company. He began the heavy construction division that focused on bridge and road construction. While growth continued on the restoration side of the business…

this new division worked on the expansion of the turnpike system throughout the Midwest. Projects completed in the Twin Cities included the Mendota and Lafayette bridges, in addition to the Highway 5 tunnel. Giertsen Company also completed bridges throughout the Midwest, and into Ohio, Kentucky, and Illinois and developed causeways as far south as Florida.

In the 1970’s Giertsen Company continued to expand and started a remodeling division to further service the growing Minnesota population. Giertsen Company’s focus also shifted to major restoration construction, with the development of tornado and storm work that sought to get customers back on their feet when disaster strikes.
