SALT LAKE CITY (AP) — The Utah Department of Transportation has started making safety improvements near a homeless resource center where cars killed three men. The Salt Lake Tribune reports the department has installed electronic message signs to urge drivers to be alert for pedestrians near the South Salt Lake center. City leaders called for immediate pedestrian safety improvements after the men were fatally struck. Police believe the men were homeless and seeking shelter at the center. Four crashes have occurred in the area since the November opening of the 300-bed men’s resource center. Additional improvements are scheduled over the next several months.
