Paving and sealcoating projects begin on state highways this week, as part of Idaho Transportation Department's ongoing maintenance of the state highway system. Here's the schedule:
- Aug. 26: Idaho 3, junction Idaho 3/Idaho 97 to Interstate 90.
- Aug. 27: Interstate 90, from milepost 30.9 (Fourth of July Creek) to milepost 40.11 (Exit 40 at Cataldo).
- Aug. 28 - 29: Fog sealing on above road sections. The speed limit will be reduced to 35 mph through the work zone area.
Seal coating is a process designed to prolong the life of the roadway surface. A thin layer of asphalt is laid down, followed by a layer of rock chips. Once the liquid asphalt has set up, excess rock chips that have not adhered are removed. Fog sealing is a thin layer of asphalt that will be sprayed over the completed, which will seal in the rock chips.
