Over time, many jurisdictions <br /> have worke in the area so accurate infrastructure records were difficult to obtain. Instead, <br /> ground pen trating radar was used to locate the old bridge and to find underground utilities and <br /> voids Great d by the broken storm pipe. <br /> The bridge remnants were found to be 20 feet long and approximately 34 feet wide and <br /> mostly cont fined within the southbound lanes of Coburg Road. The uppermost remnants are <br /> approximat ly three feet below the asphalt surface of the roadway. It appears that repair work <br /> can be completed leaving the bridge remnants intact. <br /> The slumping area is being monitored for movement and has been moving since the <br /> investigatio began just a few weeks ago. The repair is a high priority and most likely will occur <br /> within then xt six to eight weeks. To minimize disruption it is anticipated the project will be limited <br /> to night wo k and will occur in phases to avoid major road closures. The repair should take less <br /> than a wee to complete. <br /> Eugene Public Works • www.eugene-or.gov/pw <br /> 858 Pearl St eet, Eugene, Oregon 97501 • 541-682-5523 • fax 541-682-6826 • e-mail pwadmin@ci.eugene.or.us <br /> <br /> I <br /> <br />
