Chip seals scheduled for Multnomah County rural roads

Multnomah County’s Transportation Division plans to lay down a chip seal paving treatment on a number of rural county roads in the next few weeks. Travelers will experience 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. Work is scheduled Mondays to Fridays, from 6 a.m. to 4:30 p.m.

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.

Road segments that will be chip sealed and work dates in our area are:

August 3 – 8: East Larch Mountain Road (milepost 5 to milepost 7) and East Haines Road (from Larch Mountain Road to milepost 1)
August 5 & 8: Sweep and add fog seal topcoat to Larch Mountain and Haines roads

* Dates are subject to change due to weather and equipment availability. Brief traffic delays will be needed when crews return to apply lane striping after the chip seal.

Motorists can use alternate routes to avoid delays, which could be as long as twenty minutes.  Traffic using side streets and driveways adjacent to the paving may experience brief delays during a rolling closure.

Multnomah County maintains 300 miles of roads and bridges.  For information, visit
