First up: The Walmart Distribution Center is growing. The Lewiston Planning Board on Monday night approved an 8,640-square-foot dispatch building and a 770-square-foot truck maintenance garage expansion at 31 Alfred Plourde Parkway, a combined $1.7 million project. The work will remove 54 parking spaces, but with 332 spaces left, the company indicated in its application that it has plenty of room left. Related A total of 532 people work at the center, 318 during the week and 214 on weekends, spread among three shifts. The garage expansion, which is adding a truck bay, is on the southwest side of the property and new dispatch building on the northeast, according to consultants Kimley-Horn and Associates.
