Levee improvements prompt long-term Garden Highway closures

A busy section of Garden Highway will be closed through October while crews make improvements to levees around the Natomas Basin.

The U.S. Army Corps of Engineers announced that starting Monday, Garden Highway will be closed between Northgate Boulevard and Truxel Road through Oct 31.

The Garden Highway underpass at I-5 will also be closed for three weeks starting Monday.

The work is part of the ongoing American River Common Features-Natomas Basin project, authorized by Congress in 2014.

The project aims to improve 42 miles of levee surrounding the Natomas Basin.

Contractors are placing a device called a seepage cutoff wall in the existing levees. The wall is formed out of concrete 50 feet deep into the levee to prevent water from seeping through and eroding the flood protection barriers.

Because Garden Highway sits atop the levee, crews need to close the road to excavate and construct the wall.

Drivers are asked to use West El Camino Avenue as an alternate route around the closure of Garden Highway between Northgate Boulevard and Truxel Road.
