Multnomah County’s Transportation Division will begin this summer’s chip seal paving program on several rural roads in west Multnomah County next week. Travelers will experience brief delays on days when layers of oil and gravel for the chip seal are applied and swept. Roads will remain open in both directions, with flaggers and pilot vehicles guiding traffic when a lane is closed. Typical work hours are weekdays 6 a.m. to 4:30 p.m. through August.
The schedule includes rural roads in east and west county. The work schedule is as follows, with dates subject to change, depending on weather and other conditions.
- July 17-18: NW Gillihan Road
- July 19-20: NW Morgan Road
- July 21: NW Morgan and NW Gillihan
- July 24: NW Sheltered Nook Road
- July 25: NW Gillihan, NW Morgan and NW Sheltered Nook
- July 26: SE Oxbow Drive, SE Lusted Road
- July 27: NE Mershon Road
- July 28: SE Lusted, NE Mershon, SE Oxbow and NW Sheltered Nook
- July 31: SE Oxbow Drive
- August 1-2: SE Lusted Road
- August 3: SE 282nd Avenue
- August 4: SE Lusted, SE Oxbow and SE 282nd
- August 7: SE 282nd
- August 8: SE 282nd, SE Lusted, SE Oxbow
- August 9: NE Mershon and SE 282nd
Major road segments to be chip sealed are:
- NW Gillihan Road, from Milepost .22 to Milepost 1
- SE Oxbow Drive, between SE Altman Road and SE Hosner Road
- NE Mershon Road, between NE Chamberlain Road and Historic Columbia River Highway
- SE 282nd Ave, from SE Division Drive to Gresham city line
- SE Lusted Road, from SE 302nd Ave to SE Pleasant Home Road
Brief traffic delays will be needed when crews return to apply lane striping after the chip seal.
Chip seals are a cost-effective paving treatment on rural roads with lower traffic volumes. Some roads require a two-step process of applying layers of gravel and oil. Until the final layer is applied, motorists should watch for “loose gravel” signs and drive cautiously.
Motorists can use alternate routes to avoid delays. Traffic using side streets and driveways adjacent to the paving may experience brief delays during a rolling closure.
