SACRAMENTO, Calif. (AP) - A state proposal to construct two huge water diversion tunnels beneath the Sacramento-San Joaquin Delta includes plans for rerouting and reconfiguring three California highways to handle ten years of heavy construction traffic.
Engineering documents obtained by the Sacramento Bee (http://bit.ly/Y6mEnh ) outline possible detours on Highway 160 in Sacramento County around each of three water intakes proposed for the project.
The newspaper says other documents illustrate the need for new interchanges on highways 4 and 12.
According to preliminary estimates by the state Transportation Department, the costs of the rerouting could cost at least $265 million.
The Bay Delta Conservation Plan involves building two tunnels, each 40 feet in diameter and 35 miles long, to divert a portion of the Sacramento River's flow to existing water supply canals near Tracy.
