Waterloo Regional Road 15
King Street, or Waterloo Regional Road 15, is the major northwest-southeast arterial road in Kitchener, Ontario, as well as Waterloo, Ontario, where it runs north-south. In Waterloo, King Street divides the city into east and west sides, and in Kitchener, it divides the city into north and south sides. At the Conestoga Parkway, in southern Kitchener, King Street becomes the Highway 8 Expressway. King Street "resumes" about four kilometres to the east, where Weber Street is renamed to King Street and then continues to Cambridge, Ontario.
Downtown Kitchener
In Kitchener, the main segment of King Street starts at the Highway 8 Freeport Diversion, also known as Highway 8 Expressway, bend in an interchange with the Conestoga Parkway. After the Freeport Diversion passes under the Conestoga overpasses, the Highway 8 designation continues on the Conestoga west of the junction on the loop ramp, but going straight ahead defaults to King Street, which continues northwesterly through Downtown Kitchener and eventually to the boundary with Waterloo. East of the interchange, Conestoga Parkway serves as a bypass of King Street.
Although it runs southeast-northwest, King Street is labelled east-west since Kitchener was originally planned relative to the Grand River (?), which runs north-south. The same is true for the other major north-south routes in the city (such as Weber Street), and the reverse is true for the major east-west arteries in the city (although they run east-west, they are labelled north-south). The intersection of King Street and Queen Street (which was the nucleus of the early community that would become Kitchener) in Downtown Kitchener is the point from which the city's street directions are determined. King Street divides Kitchener's streets into north and south, and Queen Street divides streets into east and west.
King Street is the major street of Downtown Kitchener, with such buildings as the Kitchener City Hall and Market Square. Throughout downtown, the street is also lined with shops, boutiques, and nightclubs. Northwest of downtown, King Street is home to Grand River Hospital. It also contains television studios (for CKCO) and radio stations (96.7 Chym FM, for instance). 91.5 The Beat studio was relocated to the southern end of Kitchener/Cambridge in the Sportsworld plaza in 2010.
In 2004, when the Highway 8/Conestoga Parkway interchange was realigned to increased traffic capacity, the number of lanes headed towards King Street was reduced from two to one because of the need to accommodate the new flyover ramp from the Conestoga to Highway 8.
Kitchener to Cambridge
Another King Street, in southern Kitchener, runs north-south. It originally began at Wilfred Avenue (a residential street) and ran southward into Cambridge, wedged in between the Freeport Diversion and Weber Street.
That road was initially part of King Street downtown until the portion between Wilfred Avenue and Weber Street became the right-of-way for the Highway 8 Freeport Diversion freeway, with its terminus being redirected towards Weber Street. When the Diversion was completed in the late 1960s, travel between the two segments of King Street required one to use either the freeway's Fairway Road interchange or Weber Street and Montgomery Road.
South of Weber, the street "resumed" again and continued to Cambridge to intersect with the Freeport Diversion a second time at an at-grade Y-intersection, with the Freeport Diversion traffic being given priority. King Street continued on eastward as a divided at-grade expressway carrying the Highway 8 designation, south to Highway 401 and Cambridge. The road is often referred to as Old King Street or King East to distinguish it from the downtown thoroughfare. King East provided a link between Highway 401 and the Freeport Diversion.
In 1987, the at-grade intersection was replaced with a two-ramp interchange, when the freeway extension (secretly designated Highway 7187) of the Freeport Diversion was constructed to provide a direct freeway link to Highway 401 eastbound to Toronto. Highway 401 eastbound traffic, however, continued to use King Street East to reach the Freeport Diversion.
In 2001, the Highway 401 exit signage at King Street East was changed from Highway 8 to Shantz Hill Road since that section of Highway 8 had been downloaded from the province to municipal authorities in 1998. The Highway 8 designation was later given to the Freeport Diversion extension to reconnect it with Highway 401.
Waterloo
Upon crossing into Waterloo, King Street turns northeastward and continues until it exits the city into Woolwich Township. As in Kitchener, King Street crosses Weber Street in Waterloo (it intersects a third time at the north end of Weber Street) and also has an interchange with the Conestoga Parkway, which is now designated as Highway 85.
A major difference between King Street in Kitchener and in Waterloo, however, is that the street, upon entering Waterloo, is labelled north-south (the dividing line being Erb Street) instead of east-west as in Kitchener, like for all other major north-south thoroughfares in Waterloo.
King Street is the main thoroughfare in Downtown Kitchener but also Uptown Waterloo (the central district of Waterloo). Shops and pubs line the street roughly from the border with Kitchener until Bridgeport Road. Also, two major shopping malls are situated on King Street: Waterloo Town Square in Uptown Waterloo and Conestoga Mall at the junction with Highway 85 (both are currently in the midst of major redevelopment projects).
Woolwich and Wellesley
North of Waterloo, King Street intersects Weber Street once again, at Weber Street's northern terminus at St. Jacobs Farmers' Market.
Waterloo Regional Road 15 also continues west at the T-intersection of King Street N and Lobsinger Line that is locally known as Wagner's Corners. "Lobsinger Line" is named after a local community figure in the village of St. Clements, Ontario.
Lobsinger Line is the main road for the communities of Heidelberg, Ontario, and St. Clements, Ontario, as well as the Old Order Mennonites. Along Lobsinger Line, it is common to see signs for produce, eggs, firewood, and "No Sunday Sales" from each of the laneways.
Lobsinger Line ends at the T-intersection of Lobsinger and Waterloo Regional Road 5, in the hamlet of Crosshill, Ontario.
