Queensway approximately east of the present interchange. However, when it came time to construct this section, public attitudes had shifted and environmental concerns had come to the forefront of everyday life; new roads were now subject to intense public scrutiny. Suburbs grew along Merivale Road, prompting the Region of Ottawa–Carleton to request the MTO decommission the right-of-way along the road in 1977, which it did. The passing of the Environmental Assessment Act in 1975, however, meant that new projects were subject to a lengthy investigation of social and environmental concerns. In 1981, the MTO began an environmental assessment into a new alignment for the northern connection with the Queensway. It was approved in mid-1987, with Cedarview Drive chosen as the ideal alignment for the new freeway. The MTO set out to design a four-lane route to connect the Queensway with Highway 16 New, including a three-level free-flow interchange. A contract for construction of this interchange was awarded in late 1989 and construction began in 1990. During the 1991 construction season, contracts were awarded to construct several overpasses along the new route. This contract was completed in 1993, after which budgetary restraints prevented the awarding of further contracts. As a result, aside from the interchange at Highway 417 and some overpasses, construction activity on Highway 416 came to a standstill for two years. It was during this period that the MTO undertook an engineering review of the entire route in search of cost inefficiencies. Highways 416 and 407 were constructed during a recession in the mid-1990s. Highway 407 became a tolled highway and for a time it was mentioned in legislative debates that Highway 416 would also be tolled, but ultimately this never happened. Instead, a hiatus in construction allowed engineers to evaluate inefficiencies in bridge and cross-section designs, as well as sensitive clay soils near Ottawa. This initiative led to a cost savings of over $7 million and several of the unique design features located along the length of the freeway. Twinning and completion Work resumed on Highway 416 North following the review. It was opened from Century Road to Hunt Club Road on July 16, 1996, and completed on July 31, 1997, with the opening of the interchange with Highway 417. The cost of this section was $196 million. On December 8, 1995, in North Gower, the provincial and federal governments announced a financing deal to ensure Highway 416
