State Route 51 Northbound will be closed between
Bell and Union
Hills from 11 p.m. Friday to 5 a.m. Sunday. ADOT spokesman Doug Nintzel said crews
will be installing a Freeway Management System.“That includes
overhead message boards, but also crews are installing the ramp meters along the
on-ramps along that stretch of State Route
51 and then also freeway cameras are going in,” Nintzel said.
