 M @-@ 6 starts at exit 64 on I @-@ 196 in Ottawa County near Hudsonville . The freeway runs southeast from the interchange through the rural Georgetown and Jamestown townships toward the county line . Through this area , MDOT traffic surveys measured a traffic count of 27 @,@ 117 vehicles on average per day , the lowest along the freeway , in 2010 . At <unk> Avenue , the South Beltline crosses into Byron Township in Kent County . The freeway corridor is bounded on each side by farmland , scattered subdivisions , and small pockets of woodland . Near the Wilson Avenue interchange , M @-@ 6 curves to the northeast around the edge of the <unk> Golf Course and heads for the interchange with Byron Center Avenue . On either side of the freeway at Byron Center Avenue , there are two hospitals , Metro Health and St. Mary 's Southwest , the former located on the very southern edge of the city of Wyoming . Continuing east , the <unk> curves to the southeast and into the cloverleaf interchange complex at US 131 . This " <unk> " interchange stretches over a half mile ( 0 @.@ 8 km ) in one direction and over a mile ( 1 @.@ 6 km ) in the other , encompassing 27 bridges and 18 retaining walls . This makes it the largest freeway interchange in Western Michigan . There are four overpasses which carry M @-@ 6 over the US 131 freeway : two for the main <unk> in each direction and two for the collector @-@ distributor lanes on each side . The auxiliary lanes funnel the traffic using the interchange off the main <unk> to eliminate conflicts between merging streams of traffic . In the eastbound direction , the collector @-@ distributor lane also has access to a ramp for traffic bound for 68th Street , which runs parallel to , and south of , the M @-@ 6 freeway . No such access to 68th Street is provided for westbound M @-@ 6 traffic , although 68th Street traffic can access each direction of M @-@ 6 or US 131 .
