Document Description
The Water Authority is planning to implement the project, which would replace and realign an approximately 5,400-foot segment of the existing Crossover Pipeline that runs beneath and parallel to I-15. Development of the new realigned segment of pipeline would be constructed via a combination of trenching and tunnelling methods. During active construction, the affected segment of N. Centre City Parkway would be fully closed and all traffic would be detoured along Mesa Rock Road and Deer Springs Road. The section of N. Centre City Parkway where work is occurring would remain closed for the duration of work but would allow local traffic to access surrounding private properties. The proposed project would also develop new access structures to provide permanent access to this segment of the pipe for inspection and maintenance. Additional appurtenances, such as fiber optics, pull boxes, air vents, and a corrosion test system would be installed along the new segment of pipeline. The segment of existing Crossover Pipeline to be replaced would be removed or abandoned in place. New permanent easements are requested along portions of the realigned pipeline. No changes to the existing water supply would occur.
