 MDOT unveiled plans on March 31 , 2009 , to rebuild the intersection between Front Street and the eastern end of the Marquette Bypass during 2010 as a roundabout , replacing several intersecting roadways that connect the north and south sections of Front Street with US 41 / M @-@ 28 through the existing intersection . The previous intersection configuration dated back to November 1963 . It had been labeled as " dangerous and [ causing ] significant traffic delays " by the designers of the replacement . A traffic study concluded in 2007 that the intersection would need either the roundabout or a traffic signal with several turning lanes to accommodate the traffic needs in the area . MDOT decided in favor of a two @-@ lane , 150 @-@ foot @-@ wide ( 46 m ) roundabout retaining the right @-@ turn lanes from the previous intersection layout . These lanes will be used by right @-@ turning traffic to bypass the circle at the center of the intersection .
