Photograph taken 17 Sept 2009. The initial 4.5-mile section of The South Jetty at the mouth of the Columbia River was completed in 1896, with a 2.4-mile extension completed in 1914. Eight subsequent repairs have also been completed (last one in 1982). Jetty stone placement at the South Jetty, to date, totals approximately 8.7 million tons. Approximately 0.8 mile of the outer tip of the jetty has eroded since initial construction and is no longer functional. On Feb. 16, 2006, the Corps awarded a contract for the Mouth of the Columbia River South Jetty Interim Repair to Kiewit Pacific, of Vancouver, Wash. The interim repair contract will last two years with scheduled completion in October 2007. The Corps expects Kiewit to place about 130,000 tons of jetty stone over the 5,300-foot-long repair area on the south jetty. The base contract was awarded to Kiewit for $11.4 million to repair the inland reach of the jetty, which should be completed by October 2006. The second phase of the contract, in which the seaward reach will be repaired, should be completed in 2007. The Corps expects the contractor to place up to 130,000 tons of jetty stone in the two areas that extend over a 5,300-foot-long section on the south jetty.
