249 construction near Hollister and Willowbrook Mall

Hey, does anyone know why 249 between Hollister and Willowbrook Mall is under construction?🥲 Plus any sort of timeline because traffic there is getting bad now and adds 10-20 mins to my commute since I need to use it to go to BW 8. I would use the back roads but sometimes it makes no difference because of all the schools on Fairbanks💀
