State officials on Monday touted a public-private program that has installed thousands of brighter LED lights on Metro Detroit freeways that they say save money, promote safety and reduce energy use.

The Michigan Department of Transportation and Lt. Gov. Brian Calley made the announcement in connection with DTE Energy Co. and its Energy Efficiency Business program. Officials said nearly 13,000 new LED lights have replaced older high pressure sodium, metal halide and mercury vapor fixtures. The new lights are expected to last longer, shine brighter and are easier to install.

The lights have been installed on freeways — including Interstates 94, 75, 96, 696 and 375 as well as M-59, the Lodge and Southfield freeways — will save $2 million annually in operating costs as part of a 15-year agreement between MDOT and agencies that operate freeway lighting around Metro Detroit.
