Construction of Roosevelt Dam was a logistical nightmare because the site was so remote—nearly 60 miles from Mesa and 40 miles from the copper mining town of Globe. Although dam construction commenced on August 24, 1903, a supply/construction road first had to be built, along an old Indian pathway, in order to haul men, equipment, building materials, and supplies from Mesa to the dam site. The route presented challenges due to steep gradients and narrow right-of-ways; challenges that required more money than originally thought. Through special bond issues authorized by the Congress, Salt River Valley towns were able to bond themselves and borrow money to complete the road.
Apache Indians from the San Carlos Reservation provided the bulk of the labor for road construction. While there was initial skepticism about their ability to do the difficult road work, they soon demonstrated that they were up to the task. Louis Hill, Supervising Engineer, first said they were undernourished and too weak to work hard. He paid them only $1.50 per day ($2.00 was the average) until they became stronger. But it was not long before he rated Apache workmen above Mexican and Anglo workers. The Apache workmen lived apart from the other construction crews (who also lived in separated camps) and often had their wives and children living with them. Their talent and skill for building with dry-laid masonry resulted in a road bed that endures and portions of which can be seen today.
The new, 64-mile-long road was finished in December 1904, at a cost of over $200,000. Apache workers also built a sawmill road in the Sierra Ancha Mountains where lumber for construction of the dam was cut and milled, as well as new roads toward Globe and Payson. By the time Roosevelt Dam was finished in 1911, nearly $500,000 was spent building 112 miles of roads to the dam site at a cost of roughly $4,500 per mile. Today, this road is known as the Apache Trail.
