Caltrans – March 8, 2017 –

UPDATE: Beginning Wednesday, March 8th, U.S. Highway 101 at Last Chance Grade in Del Norte County will be under intermittent full closures during NIGHTTIME HOURS ONLY to accommodate equipment working at the side of last night’s slide on the south end of the grade.

The closures are to allow large equipment to drive “micro-piles” (steel rods approx. 8 inches in diameter which will be filled with concrete) into the ground below the remaining lane to ensure that it stays stable. Crews will drive one pile at a time, remove the equipment to allow traffic to clear, then resume driving piles.

This work will be done between 8 p.m. and 7 a.m. until this portion of emergency repair work is completed. Motorists should anticipate 60-minute delays during nighttime hours. Daytime traffic remains under one-way traffic control, but should not experience further delays as a result of this work.

Our resident engineer at the slide snapped these photos for us this afternoon, which show how the southbound lane slid down the mountain.

One thought on “The latest update on Last Chance Grade. Be aware of nighttime closures.”
  1. Thank you, Crescent City Times for the continuous updates on Last Chance Grade.
