When heavy rains triggered a massive landslide that blocked the entrance to one of the Pali Highway tunnels in February 2019, the Hawaii Department of Transportation (HDOT) had to get travelers back on this road as quickly as possible. The highway is the sole connector for many between Honolulu and Kailua. HDOT initially began by removing loose material and stabilizing the slopes above the highway. Rather than immediately reopening, HDOT also designed and constructed an innovative 80-foot long concrete “rock shed” structure adjacent to the tunnel to provide additional protection for travelers. While the 10-month closure was tough for some travelers, the public supported the project for a safe solution to protect drivers. HDOT kept the public informed throughout its progress, ensuring safety as the top priority.
