Projects include a full closure of the H-1 Freeway at night and heavy traffic on Oahu's North Shore this summer.

Signs are posted warning drivers of lane closures between 8:30 p.m. and 4 a.m. on weekdays. However, the contractors will only be allowed to do night work for one month. "From May through mid-December we have turtle nesting season and fledgling bird season that doesn't allow us to do night work anymore, so we're going to have to do day-time work," Sniffen said. "That being said in that area, day time work could be significantly impactful to traffic."

"If it's too bad, we'll pull off and wait until bird and turtle seasons end and start with night work again but we're definitely going to give it a try," Sniffen added. For now, the roughly six-mile repaving project is intended to be completed in December 2025. But Sniffen said if traffic is really bad, the repaving could be pushed back to December and go through May of next year when they are able to do night work.
