The Marshall County Commissioners will consider a change order request from USI Consultants’ Bart Trester when they meet today. Trester oversees the 7th Road project and the roundabout project on North Michigan Road in Plymouth. Trester indicated earlier this month that crews are waiting for word from the state to move ahead, barring any more issues with the HMX mix design. The mix of aggregate and asphalt binder is causing buckling pavement in other locations across the state. Crews are awaiting final approval of the combination to install the mix.
