10,000 people constructed a 380 mile road in just one hour!

In 1909, Iowa experienced heavy rainfall, that combined with an increase in automobile use, created the need for a new road. Officials, as well as the community supported the creation of a new road. 

Governor Carroll was especially instrumental in convincing people along the proposed path of the road to support its construction. The result of this support raising was the creation of the River to River Road (RRR). The idea was to create a road that was 380 miles long, and, like the name says, that stretches from river to river. 

Up to the summer of 1910, preparations were made. This included preparing machinery and materials and gathering around 10,000 men to work on the road. 

They made repairs to all the bridges, so that when they began work, they’d be ready to finish it quickly. All the men, coordinated together began work in early summer. 

They began at 9 a.m. on a Saturday. The exact date is unknown, probably in May or June, but what is known is that the road was completed by 10 a.m. that very day. Street signs went up later that day!
