Our big reveal: Salt Lake City’s pioneering protected intersection at 200 West/300 South is open for business! The 300 South project originated as part of Salt Lake City’s commitment to provide transportation choices, improve our region’s air quality, promote healthy active transportation, and create a vibrant, economically sustainable city. The new design includes Utah’s first protected intersection layout at 200 West and 300 South to create a safer destination for people visiting downtown.
