Throughout the months of July, August and September, Idaho Transportation Department striping crews will be laying down a fresh coat of paint on large sections of highways across the Panhandle. The following schedule will help drivers to be aware of upcoming temporary work zones that may affect them and plan ahead. Every year crews stripe hundreds of miles, and on heavily traveled routes like I-90, apply two coats of paint.

During striping operations teams are organized into a line of pace cars flanking the paint truck and are followed by a crash cushion trailer to ensure the safety of the crew.  This configuration of vehicles travels slowly as they paint the roadway markings to ensure lines that will last through the year. While the paint itself is very bright, retro-reflective beads are also mixed in to help catch and reflect light to improve nighttime visibility.

Pace cars alert motorists of the operation and slow down traffic so drivers do not go over the paint before it dries. It is important for drivers to avoid drifting over the lines on either side of their lane or trying to pass where striping is in progress.

Striping operations occur primarily during daylight hours and are performed in the summer when temperatures are consistently warm enough to ensure the paint dries quickly and adheres securely to the road. Most frequently these operations are carried out during weekdays, but there are occasional needs for weekend work. Crews start as early as 5 a.m. to avoid peak commute times and try to pull off so others can pass where they have room to do so safely.

Drivers who encounter the mobile paint operations are asked to be patient for the safety of motorists and crews, and to follow the guidance of all work zone signs, especially for no passing.

Updated information will be available throughout the summer on Idaho 511.
