US-23 Flex Route Lanes Between I-96 & 8 Mile Now OperationalJuly 30, 2026Jessica Mathews / news@whmi.comYears in the making, the US-23 Flex Route lanes are now operational in the Brighton and Green Oak Township areas. MDOT says it will begin phasing in operations of the Flex Route lanes on US-23 between I-96 and 8 Mile beginning today, Thursday, July 30th. Flex Route technology helps manage congestion and incidents, as well as improve safety on highways that frequently experience traffic congestion during peak travel periods. The outside shoulders are upgraded to satisfy federal requirements to be used as temporary (flex) lanes during periods of heavy congestion. MDOT built the first Flex Route on US-23 between M-14 and 8 Mile Road in 2016 and 2017.
