UPDATE: SR 190 lane closure at Success Lake extended through April

U.S. Army Corps of Engineers Sacramento District
Published March 31, 2023

The recurrent lane closure near State Route 190 post mile 23.39 will continue through April while the U.S. Army Corps of Engineers Sacramento District continues improvements of rock slope protection of bridge abutments along Success Lake. Aside from the timeline extension, no changes to the current traffic plan are planned. The extension is necessary because of recent rains that saturated the area.

The completion of the work will finalize a three-phase effort that started in January and is part of USACE’s Tule River Spillway Enlargement Project at Success Lake that will raise the spillway and the rock slope protection by 10 feet.

  • Phase 1 began on Jan. 23, with Southern California Edison removing overhead power lines and digging new pole holes along the slope.
  • Phase 2 began around Feb. 6, with USACE construction crews armoring the bridge abutments by installing rip rap stones to accommodate additional reservoir storage.
  • Phase 3 began in March and includes the installation of new SCE overhead power poles placed above the new high-water line, as well as other work by USACE.

Drivers should continue to expect delays until the end of April, as traffic control measures will be implemented to allow traffic to travel in both directions across the bridge. Any updates to the schedule or traffic control measures will be shared in advance and posted to the USACE Sacramento District website at https://www.spk.usace.army.mil/Media/News-Releases/.

The purpose of the Tule River Spillway Enlargement Project is to lower the flood risk for downstream communities by increasing the capacity of Success Lake by 28,000 acre-feet, which will also support the lake’s additional purposes of water storage and recreation.

Completion of the Tule River Spillway Enlargement Project is scheduled for September 2023. For more information about the project, visit https://go.usa.gov/xfQEd.
