I was out in Muskegon yesterday, and stopped by the Norton Shores store to see how the renovation is going there. The northern addition with the new grocery section is already nearing completion. Looking through the wall inside, It appears that the addition is maybe a couple weeks away from being ready for the move. The lights are on and coolers are installed.
You can see from this view how much of the old building will be demolished once the grocery section moves. The former seasonal area has already been demolished.
In addition, interior renovations of the retail area are starting (removing tiles and painting the ceiling, replacing floor tiles, etc.).
