City crews will begin major overnight roadworks for the E.C. Row Expressway that will see nightly delays across the month of June. On Monday, the $5 million project will see milling and paving of the east-west route get underway between Central Ave. and Walker Rd. beginning at 8 p.m. and running until 6 a.m. with the help of a noise bylaw exemption. The work will also touch ramps at Central Ave., Howard Ave., and Lauzon Pkwy. Overnight work is being done to limit daytime disruption with crews expected to wrap up for the end of June or early July.
