Leah Hogsten | The Salt Lake Tribune l-r Brent Jakobson, wife Elena Jakobson and Tiffany Skelton, who live on New Heritage Drive in West Jordan protested during a ceremony, Monday, Nov 19, 2018, celebrating completion of a $208 million project that converted four intersections into freeway-like interchanges at 5400 South, 7000 South, 9000 South and 11400 South. They complain that while a new sound wall being built at the 9000 South interchange will tower 11 feet above Bangerter, it will only be a couple of feet tall in their back yards which are at a much higher elevation — saying that creates a danger for children in the area, and also may not do much to reduce noise.
