MI SB0136

Increases the vehicle traffic threshold for abolishing existing grade crossings from 100 to 500 vehicles per day when a new roadway crossing is permitted.

Prohibits new public or private at-grade street, highway, farm, bicycle, or pedestrian crossings across high-speed rail corridor tracks after federal corridor designation, except for crossing consolidation or relocation approved by the department.

Requires the department to investigate proposed crossings and determine if locations are necessary, feasible, and reasonably safe; denies permission if grade crossing cannot be made safe.

Specifies that the party requesting a crossing bears full construction costs, including roadbed, track structure, pavement, traffic control devices, and drainage materials and labor.

Requires railroads to remove abandoned tracks and active traffic control devices within one year, while road authorities must remove passive traffic control devices; both parties maintain crossings until removal is complete.
