I-70 Mountain Corridor Right-of-Way Monumentation
Golden to Silver Plume, Colorado

Section Breakdown/ Control Network

In 2001 the JFSA Survey / Right-of-Way group along with staff from the Colorado Department of Transportation Region 1, was required to create a static survey along Interstate 70, from Golden to Silver Plume. Our team used a 5700 and a 4800 GPS system along with 4 one-man GPS survey crews to accomplish this task.

Existing Right-Of-Way Plans

In 2001 the JFSA Survey / Right-of-Way group was required to determine the existing right-of-way of a portion of Interstate 70. What made this project challenging was the length of the project, the mining claims that checkerboard the area, along with illegible Colorado Department of Transportation Right-of-Way plans, subdivision plats, and mountainous terrain. The mild winter made it possible for our crews to work nonstop until the project was completed. Much of the control that was found was initially set in the mid 1950's when this portion of the highway was monumented and built. Using a Trimble 5700 GPS, and the control network developed in the beginning of this project, we tied out existing right-of-way monuments, which were then used to develop search coordinates and finally to set the missing right-of-way corners with CDOT type II monuments.
