King's Highway 21 -  www.OntHighways.com

Before downloading, Highway 21 ran from Highway 3 at Morpeth northerly to the Highway 10/26 junction in Owen Sound.  In 1998, all portions of Highway 21 south of The 402 were decommissioned.  The new names for the downloaded portions of road are: Chatham Road 17, Chatham Road 21, and Lambton Road 21.  Most of the remaining (non-downloaded) sections of Highway 21 make up the historical Bluewater Route that follows the shores of Lake Huron.  Traffic levels vary a lot on this long stretch of highway as many of the communities the route passes through are based primarily around their respective beaches.  Some of these beach communities, while bustling in the summer are quite barren in the winter months. 


Old Style King's Highway 21 Shield

 

Southern Terminus:  Pre-1997:  Highway 3 junction in Morpeth.

                                         Current: Highway 402 interchange near Reese's Corners.

Northern Terminus:  At the Highway 10 and Highway 26 junction in Owen Sound.

Length:  Pre-1997: 327.0 km.  Current: 227.0 km.

Multiplexes:  Before 1998, Highway 21 was multiplexed with Highway 6 near Owen Sound for 16.7 km and also multiplexed with Highway 402 near Forest for 9.3 km.  In 1998, Highway 6 was more logically rerouted via Highway 70, which shortened the multiplex to 5.1 km.

Freeway:  Concurrent with Highway 402 only.

AADT (2002):  Highest: 20,900, from Owen Sound to the Grey County Mall;

                             Lowest: 1,900, from Belgrave Road northerly to Highway 86.

Road info:  Highway 21 is in respectable shape for its entire length.  Of course, due to the route's long length, its condition does vary a fair amount, from excellent to mediocre.  Traffic volumes for virtually the entire length of this highway are moderate, and due to the seasonal nature of Lake Huron, traffic is notably heavier during the summer months.  Highway 21 has a rural speed limit of 80km/h.
