This weekend, May 10-12, ITD operations crews will make changes to the right-turn lane into the east entrance of Aht’Wy Plaza to improve safety for turning drivers. These improvements will precede construction of the planned interchange.

Crews will sealcoat the turn lane on Friday to mask existing striping and will return over the weekend to sweep away any loose rocks. The turn lane is scheduled to be repainted on Monday, May 13. Drivers can expect the turn lane to be closed for a few hours each day while crews are on site.

The turn lane will be shifted to provide more separation from the through lanes of traffic, and the stop bar for exiting drivers will be moved closer to traffic to improve line of sight.

Modifications will prevent vehicles turning into the plaza from obscurring other vehicles passing through the area. A joint road safety audit with the Nez Perce Tribe in January determined that this blocking effect was a factor in recent fatal crashes.
