The Gillespie Dam was constructed circa 1920 by a local rancher, Frank Gillespie (Gillespie Land and Irrigation Company), [3] to replace an existing structure.[4] [5] As the dam was located at an important river crossing that would later become U.S. Route 80, the Arizona Highway Department – the predecessor to the Arizona Department of Transportation – constructed a concrete apron at the ...
Truck aprons are between the road portion of the roundabout and the inner circle of the roundabout. [2] On slip lanes, the truck apron is located between the road surface (bitumen) and the sidewalk. Both in roundabouts and slip lanes the truck apron is raised slightly, in an attempt to keep light vehicles on the main road surface.
After plans for a bridge across the dam fell through, the Highway Department decided instead to build a temporary concrete apron at the foot of the dam to allow cars to drive through the river until the state could build a dedicated bridge across the Gila. The apron was completed and opened to traffic in 1922.

However, the apron is not usually open to the general public, and a permit may be required to gain access. An apron's designated areas for aircraft parking are called aircraft stands. [4] By extension, the term apron is also used to identify the air traffic control (ATC) position responsible for coordinating movement on this surface at busier ...

As part of the same renovation, a 450-foot stilling basin was installed, replacing a deteriorating concrete apron. [18] [19] There have been proposals to restore power generation at the dam. [20] Proposals by the park district from 2009 proposed a $30 million plant which would generate 44 megawatts per year. [21] The proposals have not gained ...
