A chip seal is a low-cost paving treatment used on lightly traveled rural roads. The seal requires a multi-step process in which layers of oil and gravel are applied on different days, and then topped with a final oil layer called a fog seal. The full width of the road will be treated, but traffic delays should be limited to 15 minutes or less.
The schedule is as follows:
- Monday and Wednesday, July 14 and 16: NE Grange Hall Road (from Historic Columbia River Highway to SE Littlepage Road) and SE Littlepage Road (from Historic Columbia River Highway to SE Rickert Road)
- Tuesday and Thursday, July 15 and 17: E Larch Mountain Road from Milepost 3 to Milepost 4
- Monday, July 21: Add fog seal layer to all the roads treated
Multnomah County maintains these rural roads and 300 miles of roads and bridges. For more information, visit www.multco.us/roads.
