A movement to get concrete barriers installed on the 401 from Tilbury to London is gaining momentum. More than 100 Chatham-Kent residents attended a town hall-style meeting last night in Chatham hosted by MPP Rick Nicholls and the Build the Barrier group. Group member Alysson Storey says this issue affects everyone and they have worked so hard to get here. Jeff Yurek, MPP for Elgin-Middlesex-London announced a $67.8 million plan to widen the highway from four lanes to six, and install concrete median barriers between Tilbury and Merlin Road.
