About 1.5 km of Hamilton Street and Queenston Road were proposed for the traffic calming initiative, streets that both run parallel to King Street.
These proposed streets were brought forward by city staff, but are being criticized by councillors.
Mike Mann, Ward 3 Councillor told the Mike Farwell Show on 570 NEWS that these proposed streets are not ideal timing or location wise.
"King Street as you know has been under construction for probably about four years from the top of Shantz Hill, and now at the end of King Street and Bishop, so it has always been difficult to traverse that part of King Street, or any part of King Street for that matter while its been under construction."
He said many people have become very frustrated with the construction on King Street and adding slow streets around it would cause a lot of headaches.
Now, city councillors aren't against slow streets in Cambridge, but they are cautious about the location.
Mann said the city should consider waiting until the construction of King Street is complete, and to consider a consultation with residents, as they are likely to be the most impacted.
"If you want buy-in from people you have to let them know what we are going to do, and I think it's important that when we do the slow streets that we let the public know and we let them know what we are going to do, how we are going to do it, and give them some lead time before we are going to do it."
He also suggested a revaluation of slow street location after they discuss their cycling master plan.
"It will be interesting to see that and to try and work the slow streets and the cycling master plan together and come up with the ideal solution for cyclists, motorists, and pedestrians walking the streets, for a speed that will be appropriate for our communities."
For now, the decision about the slow street locations has been deferred by city council.
