How will noise and vibration impacts be mitigated throughout the corridor?
Vibration mitigation measures will include installation of concrete floating slabs under the track on a section of Cedar Street in St. Paul to isolate vibration away from buildings. Track crossovers will be relocated in a few places to where they will not affect noise and vibration sensitive or historic buildings. A crossover is a track structure that allows continuous passage for trains between two nearby and generally parallel tracks. In some locations, Metro Transit will modify its practice of activating train horns each time trains meet at grade crossings. Resilient track fasteners will be installed in locations where several sensitive laboratories are located.
