On this week’s Talking Michigan Transportation podcast, a look at transportation-related legislation being debated.

Aarne Frobom, senior policy analyst at the Michigan Department of Transportation (MDOT), and Troy Hagon, MDOT director of government affairs, break down the proposals.

Among those discussed:

• House bills 4132 and 4133. These bills, resurrected after very nearly making it to the governor’s desk in 2022, would allow the use of cameras to enforce speed limit violations in state trunkline work zones. As discussed on a previous podcast, the cameras have had a positive impact in other states.
•  Senate bill 43. This legislation, also debated and nearly adopted in the previous legislature, would:
  • Require the Michigan Department of Transportation (MDOT) to use concrete barriers or equivalent crashworthy temporary traffic barriers when closing a freeway or a portion of freeway for construction, improvement, or repair.
  • Specify that the requirement would not apply if the freeway or portion of freeway were closed for not more than three days for an emergency repair, utility crossing, maintenance, or other short-duration operation.
  • Allow MDOT to exercise its engineering judgement in designing and placing concrete barriers or equivalent crashworthy temporary traffic barriers and associated traffic control devices for each closure of a freeway or portion of freeway. 
• House bills 4352 and 4353 would allow for MDOT to restrict highway lanes to high occupancy vehicle (HOV) lanes and allow road agencies to open a HOV lane to other classes of vehicles (trucks or automated vehicles). The legislation also allows enforcement of I-75 HOV lanes and Detroit and Grand Rapids bus lanes.
