ODOT will clear brush and small trees along the southbound side of U.S. 101 in the area south of the Chetco River Bridge in Harbor. This will improve safety by removing trees that could fall in winter storms, improve visibility by allowing more sunlight to reach the roadway, allow pedestrians easier travel due to brush encroaching on sidewalks, and prevent autumn foliage from blocking catch basins and causing flooding.
From Monday to Friday, Sept. 14-18, watch for southbound lane and shoulder closures during daylight hours. Southbound traffic may be shifted into the center lane. Expect congestion and delays during peak travel times.
The southbound sidewalk will be closed when work is taking place. Pedestrians are advised to use the sidewalk along the northbound lanes.
DOUGLAS COUNTY
INTERSTATE 5 (Pacific Highway), MP 95, Canyon Creek area hazard tree removal ($50,000)
This project will remove hazard trees (dead or visibly dying) on state right of way along the southbound curve at and around milepost 95. These trees were damaged in a fire a few years ago.
Work will start on Monday, Sept. 14, and is scheduled from 7 a.m. to 3:30 p.m. each Monday through Friday. This project is scheduled for completion by the end of September.
Rolling slowdowns will be used in both directions of I-5, affecting northbound traffic from MP 87 to 95 (Azalea to Canyon Creek) and southbound traffic from MP 103 to 95 (Tri City to Canyon Creek). Flaggers will hold traffic at the following on-ramps: NB Exit 88 (Azalea) and SB Exit 103 (Tri City), Exit 102 (Gazley Road), Exit 101 (Riddle Road), Exit 99 (North Canyonville), Exit 98 (Canyonville) and Exit 95 (Canyon Creek). Most delays will be less than 20 minutes.

Watch for weeknight (6 p.m. to 10 a.m., Sunday night to Friday morning) lane closures in the southbound directions. At night, watch for traffic control devices and workers in the closed lane of travel.
Construction may require intermittent nighttime and morning (6 p.m. to noon) closures of the southbound on-ramp at Exit 129 (Del Rio Road). Use alternate routes.
INTERSTATE 5 (Pacific Highway), Exit 140 and Exit 142, Maintenance paving ($390,000)

This project will resurface a five-mile section of Oregon 42 between Winston and Interstate 5, install a new traffic signal at Rolling Hills Road, add safety features to help reduce crashes through the Green District, and upgrade sidewalk curb ramps to better accommodate wheelchair users and other pedestrians. The project is scheduled for completion in September.
In September, contractors plan to perform miscellaneous work throughout the project area. This may require day and night lane closures on Oregon 42. Construction is usually scheduled from 6 p.m. to 7 a.m., Sunday night to Friday morning. Watch for roadside message boards and flaggers.
When the new striping and new white pavement arrows are applied, a “zipper merge” will be introduced to eastbound Oregon 42 as traffic approaches the bridge over I-5 and the northbound ramps. Oregon 42 drivers heading to Roseburg and northbound I-5 are asked to use both eastbound travel lanes through the Green District, then take turns merging when the highway narrows to one lane. Please drive with caution and be patient with other drivers as they learn the new merging process. Watch for new signs, striping and pavement markings that encourage drivers to take turns merging.
At Exit 119, watch for intermittent nighttime closures of the northbound on- and off-ramps. Watch roadside message boards and construction signs for updates.
Nearby residents should expect nighttime construction noise throughout the work zone.
OREGON 138E (North Umpqua Highway), MP 29-31, Paris Reservoir Landslide repair project ($6,989,262)
