Gearhart was the Linn County Engineer at the time, and Ford Paving Company of Cedar Rapids, Iowa, constructed the project. Northwestern States Portland Cement Company of Mason City donated 3,000 barrels of cement, and Linn County provided grading, draining, and construction of the 16 ft wide pavement.
