Highway 21 (Ontario)
Encyclopedia
King's Highway 21, commonly referred to as Highway 21, is a provincially maintained highway in the Canadian
province of Ontario
that begins at Highway 402 mid-way between Sarnia
and London
and ends at Highway 6, Highway 10 and Highway 26 in Owen Sound
. The roadway is referred to as the Bluewater Highway because it remains very close to the eastern shoreline of Lake Huron
.
Highway 21 is often subject to winter closures due to lake effect caused snowsquall
, which can create sudden whiteout
conditions along the Lake Huron shoreline. Several Emergency Detour Route
s have been established further inland to guide drivers around such closures. Care should be taken during the winter months, as these storms can progress rapidly and unexpectedly.
Highway 21 is a long lakeside route through southwestern Ontario
which serves numerous communities along the eastern shoreline of Lake Huron. Once over 100 kilometres (62.1 mi) longer than it is today, the highway now begins at Highway 402 near the community of Warwick
, where it progresses north through the towns of Forest
, Grand Bend, Goderich
, Point Clark, Kincardine
, Tiverton
, Port Elgin
, and Southampton
. At Southampton, the highway veers away from the Lake Huron shoreline and travels east to Owen Sound.
The route is generally smoothly-flowing, but can be somewhat congested near main towns in the summer from tourists and cottage
rs. During the winter months this trend is reversed. Highway 21 is often subject to closures at various points as it lies on the lee shore
of Lake Huron
. Lake effect snow squalls frequently subject motorists to poor visibility and slippery conditions, leading to the closure of the highway. Highway 23 provides an alternative inland route.
circa 1860. When James Miller Williams
, a Hamilton
businessman set out one day from during a drought to dig a well, he chose a spot downhill from an existing oil seep in the village of Black Creek. Instead of encountering water, Williams hit a shallow oil deposit. As a result of the ensuing oil-boom, which would begin the petroleum industry in North America, Williams laid out the village and changed its name to Oil Springs. Two competing plank road companies were formed, the Black Creek Plank Road Company (of which Williams was a principal investor) and the Sarnia to Florence Plank Road Company, both of which aimed their roads through Oil Springs. Although both roads were constructed, the former company was more prosperous in its endeavours; in 1886, a significant portion of the Sarnia to Florence Plank Road was closed up and turned over to local property owners. The Black Creek Plank Road Company meanwhile had transformed the muddy quagmire
of a path into a well-maintained road. By 1863, three miles of road south of Wyoming had been paved, and the remainder south to Oil Springs planked (the Sarnia Road followed two years later). However, as the oil boom faded, so too did improvement to the road. The Black Creek Plank Road
On May 23, 1927, the Department of Highways assumed the unpaved road between Highway 7 at Reece's Corner and Highway 3 at Morpeth, via Dresden
, Thamesville and Ridgetown as Provincial Highway 21; this was changed to the current King's Highway 21 in 1930.
That year, the department set out to improve the new highway. Concrete slabs were laid between Petrolia and Highway 7, as well as along a 7.25 kilometres (4.5 mi) section between Thamesville and Dresden. The following year, the route was paved between Dresden and Edys Mills before the effects of the Great Depression
forced the department to concentrate on paving Highway 22. The election of a new government in mid-1934 led to the resumption of work in June as a depression relief project. New equipment (namely a Caterpillar Excavator), as well as the expertise of Andy Newman, an engineer who was hired when he demonstrated his abilities with the machinery upon passing a construction site on his drive home. Newman, who helped design the machine that nobody else could operate, allowed work to proceed at a much faster rate than before. The machinery could dig quicker than 50 men, and this effort showed when the gap between Petrolia and Edys Mills and the remaining gaps between Dresden and Thamesville were graded and paved by the end of the summer. On October 19, 1934, Highway 21 was officially opened by Robert Mellville Smith, deputy minister of the Department of Highways.
On April 4, 1934, Highway 21 was assumed through Huron County as far north as Goderich. This was followed by the assumption of a section through Bosanquet Township
on April 18, creating a 40.6 kilometres (25.2 mi) concurrency with Highway 7 from Reece's Corners to Thedford. From there, the route travelled through Thedford to Port Franks, where it merged into the present highway.
A final 137.4 kilometres (85.4 mi) extension to Owen Sound was assumed on May 15, 1935,
bringing the highway to its greatest length of 333.1 kilometres (207 mi).
Meanwhile, on April 11, 1934, the department assumed control of a road connecting Highway 7 with Forest as Highway 21A. It was later extended to connect with Highway 21 at Port Franks on August 19, 1936.
By 1938, Highway 21A had been renumbered as Highway 21, and Highway 21 through Thedford renumbered as Highway 82.
During the late 1950s, a small bypass of Highway 21 was constructed north of Goderich, avoiding a nearby hairpin turn
.
During the early 1980s, the construction of Highway 402 east from Sarnia resulted in a shift in the route of the highway. The route was extended north from Reece's Corners to Exit 25, while the section from Highway 7 north to Exit 34 was "downloaded", or transferred to the local municipality in which it resided.
Further transfers were performed in 1997 and 1998. On April 1, 1997, the section of Highway 21 from Highway 401 south to Morpeth was transferred to Kent County
.
On January 1, 1998, the section between Highway 401 and Highway 402 was transferred to Kent and Lambton counties.
