Trigon served as the prime engineer on this project, which consisted of the design of improvements to transfer all existing water pipeline connections, laterals and private metered service lines from an existing 8-inch water main, on East 70th Street from Creswell Road to East Ridge Drive, to an existing parallel 20-inch water main that is remaining in place. Approximately 1,500 feet of the 20-inch main was also replaced/relocated, and portions of it were installed by horizontal directional drilling.

The existing 8-inch water main was abandoned in place upon completion of all potable pipeline transfers.

This utility relocation project was performed in strict coordination with the Louisiana Department of Transportation and Development’s (DOTD) roadway project, (SP#102-02-0031) Route LA 511, Line Avenue to Fern Avenue Roadway Widening.

The project was designed and constructed in accordance with both City of Shreveport and DOTD standards. Construction was completed in 2013.
