Why only one bridge?

I have a large property with lots of metal sheds. I need to setup another bridge to be able to reach an additional out door smart plug. The Smart Plug I want to install is out of reach from my current bridge. Why can’t I use more than one bridge? Is there a way around this? Why does the smart plug that connects via Wi-Fi need a bridge anyway? FYI, I did try to move my bridge in between both smart plugs but still to far to reach both at the same time. Thank you in advance!!BigGreen
