Sections of Garden Highway will be closed to all traffic beginning July 8

The U.S. Army Corps of Engineers announced that major levee improvement construction in the Lower Natomas Basin will require extended road closures on Garden Highway beginning July 8.

Garden Highway will be completely closed to all traffic in both directions, requiring drivers to take alternate routes, at the following project areas:

  • Underneath the Interstate 5 overpass for up to three weeks beginning July 8 through July 29. Interstate 5 on- and off-ramps at Garden Highway will remain open, but drivers will not be able to cross under I-5.
  • Between Northgate Blvd and Truxel Rd, starting July 8 until October 31.

Other traffic information include:

  • Beginning this Thursday, June 27, Garden Highway will be closed underneath I-5 between the highway ramps during the overnight hours of 9 p.m. to 5 a.m. This will be a full closure in both directions but will reopen during the day before major morning commute hours. Overnight closures will continue until the full closure begins on July 8.

Project Background

Construction crews are improving the levees surrounding the Natomas Basin, which in some locations includes installation of a seepage cutoff wall approximately 50 feet deep into center of the levee. In the lower basin, Garden Highway sits atop the levee in some areas, which means the only way to construct levee improvements is to shut down the roadway.

This work will significantly disrupt traffic in the area. Sections of Garden Highway will be closed through this summer and fall, and additional shorter closures will be required in 2020.

“This construction project will deliver a 21st century flood reduction system for the Natomas Basin,” said John Hoge, Senior Project Manager for the Corps’ Sacramento District. “It’s going to be inconvenient for a bit but this work will lower the flood risk for the communities behind the levee.”

Staging areas located along Azusa Street will also result in additional truck traffic in the area.

“Though this work requires closures of Garden Highway, the City of Sacramento has a strategic traffic control plan and public information campaign in place to help minimize the inconvenience,” said Councilmember Jeff Harris. “The result will be greatly improved flood protection for the Natomas Basin. It will also help keep flood insurance rates in the area low as they could increase up to 400 percent without this critical levee improvement.”

This work is part of the “American River Common Features – Natomas Basin” project authorized by Congress in 2014. It will ultimately reinforce 42 miles of levee surrounding the Natomas Basin in partnership with the State of California and the Sacramento Area Flood Control Agency. Levee improvements will continue for the next several years and may require additional road closures. The project is scheduled for completion in 2024.
