Kachemak Drive to open Tuesday night

With the last bit of work to be done this afternoon, the west end of Kachemak Drive should open tonight. Kevin Jones, the local manager of the Alaska Department of Transportation and Public Facilities, Homer area, said another load of rock and jute matting needs to be put in on a rebuilt slope where a 70-foot section of road collapsed on April 19, but after that’s done, the road will open.

Officials had said last week it might take two weeks to repair the road, but it took just nine days to dig out the mudslide, put in new drainage and repair the road. Warm, clear weather and a good crew helped, Jones said.

“Everything just came together,” he said.

DOT&PF used pavement milling — ground up asphalt from last summer’s road repaving — as the top layer for the repaired road. After the road has set up, crews will pave the stretch. Jones said there will be some flagging, but the road won’t be closed again.

A mudslide about 8 a.m. April 19 took out the road on the hill about a half-mile from the intersection with Homer Spit Road. The side of the hill slid into Mud Bay, including a clump of 100-foot tall spruce trees. Engineers left the toe of the slide where it landed to keep silt from washing into the wetlands — important shorebird and animal habitat — and to hold repairs. Already alders have started to bud and devil’s club grown back.

Jones said workers redid a drainage ditch on the uphill side, putting in cobble rock wrapped in filter fabric. As soon as that went in, the mud below it dried up, Jones said.

Jones said he thought a series of causes and not just one thing made the slope collapse. Saturated soils, a warm winter with no real frost and remnants of a World War II era corrugated road all contributed.

“I truly think it was a perfect storm,” he said. “Everything lined up.”
