Southbound I-75 traffic in Oakland County will begin shifting to newly constructed lanes on Thursday evening. Southbound I-75 traffic has been sharing the northbound side of the freeway between Adams and 13 Mile roads due to road and bridge reconstruction. Beginning at 7 p.m. Thursday, one lane will be closed on southbound I-75 between Adams and 13 Mile roads to prepare for the switch. Officials say that southbound I-75 traffic will be utilizing the newly constructed southbound lanes by 5 a.m. on Friday. Officials say there will be two lanes open for both directions on I-75 between 8 Mile and Adams roads during Labor Day weekend.
