ACHD Crews Try to Stay Ahead of Icy Roads With 'Mag'

Posted By on Fri, Jan 10, 2014 at 9:50 AM

In the shadow of Jan. 9's terrible 44-vehicle pileup on Interstate 84, which sent multiple people to area hospitals, Ada County Highway District crews were out again this morning—beginning at 4 a.m.—spreading de-icer and sand on hilly roads, intersections and bridges.

ACHD officials said most major roadways remained passable this morning, but key areas needed treatment after near-freezing temperatures created some trouble spots. In particular, crews focused on the Boise Foothills near Table Rock and Seamans Gulch roads and the north side of State Street.

With particular concern over temperatures hovering just below or above freezing, an ACHD crew supervisor said, "If the temperatures drop, we could have some issues, so the mag (magnesium chloride) will keep those (roads) from icing up."

ACHD officials said the Jan. 9 melee included 12 accidents on I-84, the most serious occurring when a logging truck jackknifed, striking a number of vehicles and trapping one motorist for nearly an hour before he was extricated and rushed to a local hospital.
