Lanewood Street - pipeline construction progressing

Over the last few weeks, crews have been busy installing pipe along Lanewood Street. Next week as construction progresses, additional traffic detours will be in place around Lanewood Street, between Boones Way and Douglas Circle. The road will be closed during work hours (7 a.m. to 6 p.m., Monday through Friday). Access will be allowed for local residents and emergency vehicles within the closed area. For more information about construction and road closures, visit work underway.

Douglas Circle - pipeline construction

Crews will install pipeline along the southerly leg of Douglas Circle, then onto a portion of Upper Drive after work is complete along Lanewood Street. This is expected to begin in early April and take about a month to complete. Work along Twin Fir Road will begin in summer.

Upper Drive - water line relocation

Crews have installed a temporary bypass line on Upper Drive. Once work starts on Upper Drive for the large pipeline, the temporary line will be tested and water services transferred.

Iron Mountain Boulevard - irrigation line replacement

Next week, crews will begin replacing an 8” irrigation line serving the golf course on Iron Mountain Boulevard, near Mulligan Lane and Fairway Road. The work should take about a week to complete. Work hours are 7 a.m. to 6 p.m., Monday through Friday. During this time, the road will remain open but flaggers will guide traffic through the area.

Chandler Road - pipeline construction starting soon!

Next week, an additional crew will begin installing the large 42” pipeline along Chandler Road, near 10th Ave. Work will then progress west along Iron Mountain Boulevard. Work hours will be 7 a.m. to 6 p.m. Monday to Friday. During the work, there will be a single lane closure on Chandler Road. Please watch for flaggers and expect some temporary delays.
