About Us

Our Beginning…

Bob and Norine Canney founded Shamrock Construction Company in 1966 in Newhall, Iowa. In 1972 they moved the company to Coralville and became one of Iowa City/ Coralville area’s asphalt paving companies

In March, 2003 after the death of Bob Canney, River Products Company, Inc. of Iowa City purchased the assets of the company and formed a new entity called Shamrock Construction Company, L.L.C. They remain one of Iowa City/ Coralville area’s premier asphalt paving companies.

Many of the faces of the crew look familiar, as the employees of the old company were hired by the newly organized Shamrock Construction Company. Terry Miller, Supervisor of Field Operations, Lawrence Graper, Jim Weno, Toby and Josh King, Jerry Short, bring a combined 100 plus years of industry experience to Shamrock Construction Company and their customers.
