List of numbered roads in Waterloo Region

Waterloo Regional Road 4 is an arterial road located in the Region of Waterloo, Ontario, Canada. It is a major east-west thoroughfare through the city of Kitchener, where it is known as Ottawa Street. Despite running east-west, Ottawa Street is labeled north-south, with King Street being the dividing line. Upon passing Trussler Road westward out of Kitchener and entering Wilmot Township, Waterloo Regional Road 4 is renamed Bleams Road.

In Kitchener, Ottawa Street intersects the Conestoga Parkway at two points. However, only the first intersection on Ottawa Street North (between the Freeport Diversion and Highway 7) is served by a full signed interchange. The second intersection, on Ottawa Street South west of the Freeport Diversion, must be accessed via the Homer Watson Boulevard interchange.

Three major shopping centres are located along its route. Stanley Park Mall is situated on Ottawa Street North at the intersection with River Road. Ottawa Street South is the home of two power centres: the Sunrise Shopping Centre is located at the intersection with Fischer-Hallman Road, while the Laurentian Power Centre is at the intersection with Homer Watson Boulevard. Ottawa Street South is also the site of the Concordia Club, a major festhalle which hosts up to 4,000 revelers during Oktoberfest each year.

An expansion of the eastern end of Ottawa Street is planned; it will cross the Grand River toward Breslau and the Region of Waterloo International Airport.

Waterloo Regional Road 6 is an east-west arterial road in the Region of Waterloo, Ontario, Canada. It passes through both Wilmot Township and the city of Kitchener, with its course and name changing several times.

Waterloo Regional Road 6 begins at Waterloo Regional Road 51 (Foundry Street) in the village of Baden, where it is known as Gingerich Road. Travelling northeastward, it merges with Waterloo Regional Road 1 at the eastern edge of the village and takes the name of Waterloo Regional Road 1 within Baden, Snyder's Road East. From this junction its course changes east heading towards Kitchener, passing through the village of Petersburg along the way.

Upon entering Kitchener, Waterloo Regional Road 6 takes the name Highland Road and becomes a major thoroughfare through the western half of the city. It has major intersections with Waterloo Regional Road 58 (Fischer-Hallman Road) and Waterloo Regional Road 50 (Westmount Road) before meeting with Queen Street South near St. Mary's General Hospital.

From here, Waterloo Regional Road 6 turns left onto Queen Street South and enters downtown Kitchener. At Waterloo Regional Road 53 (Courtland Avenue), it turns right and briefly has a concurrency with R.R. 53 before turning left onto Benton Street, which is the heart of the city's Oktoberfest celebrations each year.

At Waterloo Regional Road 15 (King Street), Benton Street becomes Frederick Street; it is here that the headquarters of the Regional Municipality of Waterloo are located, as well as several provincial court houses and the Frederick Mall. After passing Waterloo Regional Road 56 (River Road), Frederick Street curves northeastward again, before it (as well as Waterloo Regional Road 6) ends at Waterloo Regional Road 55 (Victoria Street), also known as Highway 7, which continues eastward to Guelph.

Waterloo Regional Road 10 is an arterial road located in the Region of Waterloo, Ontario, Canada. It is a major north-south thoroughfare through from Wallenstein, Ontario (Line 86) to St. Clements, Ontario (Lobsinger Line), where it is known as Herrgott Road.

Waterloo Regional Road 10 also used to run from Lobsinger Line to Weimer Line, along Moser Young Road. This has since been downloaded to the Township.

Waterloo Regional Road 15, or King Street is the major north-south arterial road in Kitchener, Ontario, as well as Waterloo, Ontario. In both Kitchener and Waterloo, King Street divides the city into the east and west sides. King Street "resumes" in southern Kitchener and continues to Cambridge, Ontario.

Waterloo Regional Road 39 is an arterial road in the Region of Waterloo, Ontario, Canada. It runs entirely within the city of Cambridge, just south of Highway 401.

Regional Road 39 begins in the Preston section of Cambridge at Highway 8, where it is known as Eagle Street North. Eagle Street runs a somewhat hilly course and intersects with three railway lines before leveling out, where car dealerships begin to line its northern edge.

At the junction with Highway 24, Eagle Street changes its name to Pinebush Road. It is here that a large Home Depot store (which used to be a Knob Hill Farms supermarket) is located, as well as a shopping centre containing a Wal-Mart, among other things. After its intersection with Waterloo Regional Road 36, better known as Franklin Boulevard, Pinebush Road enters an industrial area, through which it traverses before ending at Waterloo Regional Road 33 (Townline Road), just west of Puslinch Lake.

Waterloo Regional Road 57, also known as University Avenue, is an east-west arterial road located in Waterloo, Ontario, Canada. It gets its name from the two major institutions of higher education, Wilfrid Laurier University and the University of Waterloo, that are situated along its route.

University Avenue begins at Northfield Drive in the northeastern corner of the city. From there it curves southward, paralleling the Grand River before turning west again prior to the intersection with Bridge Street. After an interchange with the Conestoga Parkway, it goes on to meet many of the major north-south arterial roads of Waterloo. The campus of Wilfrid Laurier University is just past the intersection with King Street, and the University of Waterloo campus can be found between Albert Street and Westmount Road.

After passing the University of Waterloo, University Avenue turns southwest to meet Erb Street (another major east-west road in Waterloo), then curves west again to meet Fischer-Hallman Road. It ends at a roundabout at Ira Needles Boulevard on the western edge of the city.

University Avenue's circuitous routing creates the unique situation of being parts of both the northern and southern municipal boundaries of the City of Waterloo.

Waterloo Regional Road 69, or Manitou Drive is a north-south road in the southern part of the city of Kitchener, Ontario, Canada.

Manitou Drive begins at Fairway Road and Courtland Avenue; the Manitou Drive intersection delineates Fairway Road from Courtland Avenue.

From this intersection, Manitou runs southward, passing through mainly industrial areas, including an intersection with Bleams Road. (Plans to extend Bleams Road easterly to Wilson Ave and the planned River Road extension may include converting this intersection to a roundabout.)

Homer Watson Boulevard is Manitou Drive's southern terminus, although the street itself continues beyond Homer Watson as Doon Village Road, the main artery of Kitchener's Pioneer Park neighbourhood.
