Thompson Road South, between Louis St. Laurent Avenue and Britannia Road, is being widened to support growth in the community. This roadway is currently a two-lane rural road, which will be reconstructed to four lanes. The Environmental Assessment process involves four phases. Phases 1 and 2 of the Class Environmental Assessment (EA) process were addressed through the approved Boyne Survey Secondary Plan.

Phases 3 and 4 of the Municipal Class EA process for this project are now complete. The final Environmental Study Report (ESR) is available for public review online on Let's Talk Milton or in hard copy form at Town Hall, Engineering Services, 150 Mary Street.
