Caltrans 07-343204 I-405 Slope Repairs at Rinaldi Street Project

Sukut will reconstruct the steep earthen slopes along Interstate 405 between Rinaldi Street and the interchange with Interstate 5.  Since its original construction, the slopes along this stretch of the freeway have eroded significantly.  Sukut will regrade the slopes, remove the old drainage systems, and at two locations install concrete-filled buttresses.  Sukut will also install about 550 linear feet of new drainage pipe and replace the damaged concrete ditches.  Nearly 900,000 square feet of a  wire mesh anchoring system will then be installed to protect the slopes from future erosion.
