Douglas Loop Reconstruction

Oregon City, Oregon
Clackamas Community College Education

With almost no structural base under the existing road, Douglas Loop had become cracked, worn, and well beyond its design life.  Replacement was necessary and was completed in phases.  For the northern-end replacement, a modified version of Full Depth Reclamation (“FDR”) was utilized, which does not require as much haul off and import of soil and rock as more traditional methods.

Replacement of the NE and NW quadrants was completed in two phases to allow continued access to the campus.  Work was completed over the summer in time for the start of school in the fall.  In total, 3,478-LF of roadway was replaced in this phase of development.

The Southern portions of the loop road were replaced in phases as well, in conjunction with other facility updates and campus improvements being completed.  The replacement was part of the College’s bond program, with the new loop road now having a 40-year design life.
