SPL-2021-04-14-NLH State Route 71/91 Interchange Improvement Proj

Los Angeles District
Published April 15, 2021

A Supplemental Environmental Assessment has been prepared for use by the U.S. Army Corps of Engineers  to supplement the EA that was prepared for the previously approved Project in 2014. As addressed in the 2014 EA, the previously approved Project would improve the SR-71/SR-91 interchange by constructing a new direct flyover connector from eastbound (EB) SR-91 to northbound (NB) SR-71. The Project also included bridge widening and restriping of SR-91 EB lanes, modification or construction of new drainage facilities, grading of hillside slopes, construction of retaining walls, SR-71 realignment and widening, and modification of access driveways. Some components of the Project are proposed on Federal land west of and downstream of the Prado Dam and Reservoir along the Santa Ana River, which is part of the Federal levee system.
