| 摘要： | The mountain is also home to a number of transmission towers which have served as central hubs for the city's wireless and VHF networks since 1965. But when the existing towers could not safely support new equipment while also complying with loading standards, the city made plans to construct a new 36.6m-high tower at the mountain's summit. However, the access road leading to the construction site was in a poor state of repair due to its many blind spots and steep grades. This meant that getting the materials and equipment required for the construction of the new transmission tower would be impossible. The existing road was also too narrow to cope with the 91 tonne crane needed to erect the tower. The city tasked Hunter Contracting, a heavy civil construction company based in Gilbert, AZ, with improving the 1.34km stretch of winding road to make it safe to use and also to provide enough space for the crane. |
