Crews under contract with the state Department of Transportation are busy installing a retaining wall to shore up an eroded bank along La Honda Road near the intersection with Friars Lane.
Work on at least one retaining wall further west and further uphill on La Honda Road had been underway after storm water runoff caused the roadbed to subside just east of Grandview Drive. But problems arose with utility lines, leading to a need to take down trees, which then led to a delay on the roadwork and the start of work on a second retaining wall about one mile to the east at Friars Lane, foreman Joel Duckworth of Granite Construction told the Almanac.
At Friars Lane, a section of the road's shoulder had eroded to such an extent that a vehicle traveling past at night could easily run off the road and descend 15 to 20 feet into mud deposited there from erosion by storm water runoff.
As the photos accompanying this story show, the heavy equipment is sitting on a flat earthen table. This new surface was built by crews to accommodate a mobile drilling rig and the drilling of post holes into the rebuilt shoulder to accept long pilings to form a skeleton for a retaining wall, Mr. Duckworth said.
