Due to weather-related damage, westbound Interstate 84 closed between Nampa and Caldwell on Wednesday so that crews could conduct critical repairs to the pavement, the Idaho Transportation Department announced about 7:40 a.m. Wednesday.
Crews were on site all day. At 7 p.m., the right lane of westbound Interstate 84 was blocked. ITD was reporting delays in the westbound as well as eastbound lanes.
ITD also cautioned drivers throughout the Valley on Wednesday to watch for potholes and other pavement problems, and provided a video on how potholes form.
“During times of high moisture and multiple freeze-thaw cycles, ... older sections of roadway often show sign of stress with potholes and broken pavement,” ITD said in a news release. “Water seeps into cracks and saturates the base material below the roadway surface. Ice expands in the cracks and base material, loosens the road surface, and it collapses as it melts and traffic drives over the top.
Never miss a local story.
“There is usually enough time during most winter storms for our road maintenance crews to complete repairs,” ITD Chief Highway Engineer Kimbol Allen said in the release. “So far this winter season, however, crews have had little time between storms to do much more than prepare for the next storm to hit.”
