Highway 417 entering the west end of Ottawa looks considerably different these days – and McIntosh Perry played a huge role in that upgrade.
The engineering and related professional services firm successfully provided contract administration work for the expansion of Hwy. 417 from the junction of Hwy. 7 easterly to Eagleson Road. This multi-
Totalling about 10 kilometres, the project included many aspects, such as an advanced traffic management system which provides traffic cameras along Hwy. 417 from the 416 interchange out to Hwy. 7.

“This project involved a difficult amount of traffic and volume,” MacHardy said, noting the team worked around peak periods with most of the construction being completed at night and on weekends.
Interestingly, significant samples of sandstone were removed from an ANSI-
MacHardy said he was satisfied with completing the project on time, while still being able to minimize the impacts to the community and provide a quality product. “All our staff are local and will be able to benefit from the widening in the future,” he said, noting it enhances the community. “I’m proud of the way the job turned out considering the amount of staging and external pressures we faced.
