On the other side of the river, between the interchanges with Mavis Road and Hurontario Street (formerly Highway 10), Highway 403 skirts to the north of Mississauga City Centre, as well as the Square One Shopping Centre. After a split with Eastgate Parkway, the freeway abruptly curves to the north. As the curve straightens, Cawthra Road's lanes converge with the freeway to form a collector-express system as it approaches the interchange with Eglinton Avenue. After crossing Matheson Boulevard, this segment it begins to diverge into a sprawling interchange, with the collector lanes forming the effective beginning of Highway 410, which runs northward to Brampton, and having connecting ramps to Highway 401 westbound. At this point, Highway 403 curves east and ends soon after by feeding into both Highway 401's eastbound collector and express lanes.
