BOISE COUNTY – Travelers along Highway 21 in Boise County can expect delays starting next Monday and into the fall of next year.
The Idaho Transportation Department announced a resurfacing project will cover 20.4 miles of the highway from Mores Creek Summit to Clear Creek Bridge near Lowman.
Crew will be adding a Stress-Absorbing Fiberglass Layer with Emulsified Asphalt (SAFLEA) on two adjoining sections of Idaho 21 (milepost 52.3 to 60 and 60 to 72.7), slope stabilization and upgrading guardrail at existing locations.
A SAFLEA road treatment is a seal coat with a coating of chopped glass fibers between the oil and the gravel aggregates to enhance durability and reduce cracking.
One lane of travel will remain open, with flaggers and pilot cars helping to guide traffic. Crews will work a 7 a.m. to 5 p.m. schedule Monday through Thursday and will work half days on Fridays. No work is allowed on the weekends.
The $3.9 million project is slated to finish in October 2013.
