Walmart customers across America will soon notice more changes at stores.

One-way aisles.

To further minimize the spread of COVID-19, the retail giant plans to have one-way aisles in all its more than 4,700 U.S. stores by the end of May, Walmart spokesman Casey Staheli confirmed Thursday.

The plan is already being rolled out in some stores, such as in Center, Texas, which announced the change on its Facebook page.

According to the post, the policy is designed to increase social distancing and give customers more space in each aisle.

There will be floor decals in place to help indicate the direct traffic flow and customers will find green “Shop This Way” decals indicating the entrances of each aisle as well as red “Do Not Shop This Way” decals to tell opposing traffic not to enter the aisle.

Walmart and Sam’s Club began requiring all employees to wear face masks to work on April 20.

Walmart has also been limiting the number of shoppers in stores.
