 The northbound I-17 off-ramp at Bumble Bee Road will also be closed during this same time frame. The speed limit along the detour route will be 25 mph. To accommodate flex lane construction, there will be several overnight closures in this same area over the next couple of months. The entire I-17 improvement project is on schedule to be completed in 2025. School will be back in session soon and the Prescott Police Department wants to make sure motorists do their part to keep kids safe.
