POLK COUNTY -- The gathering of trucks and heavy equipment next to Highway 22 near the interchange with Highway 99W isn't another paving project. It's maintenance work of a different sort.
NW Natural Gas crews are installing replacement main lines along Highway 22 and Rickreall Road in a project slated to run through the end of October.
Workers are replacing an old 8-inch main with a new 8-inch high-pressure coated steel main line along Highway 22. On Rickreall Road, crews are replacing and upgrading an old 4-inch non-coated steel line with an 8-inch, high-pressure coated steel main pipeline.
"(That) will increase our system capacity to the Rickreall, Independence and Monmouth areas," NW Natural Gas spokeswoman Jenna Cooper-Gross said.
Also along Rickreall Road, crews are putting in a 2-inch distribution line.
Cooper-Gross said the projects are part of a long-term bare, or non-coated, steel main replacement program. NW Natural is systematically replacing the non-coated lines.
Crews started work in August.
