History of King's Highway 10:

King's Highway 10 is a major trunk highway which links the Greater Toronto Area with Orangeville and Owen Sound. The highway traverses a mostly rural portion of Southern Ontario, occasionally passing through some cities and small towns. The principal towns located along the highway are Brampton, Caledon, Orangeville, Shelburne and Owen Sound. The highway was first established in 1920 when the road from Brampton to Owen Sound was assumed as a provincial highway. The highway was later extended from Brampton to Port Credit. Canada's first cloverleaf interchange was completed in Port Credit at the junction of Highway 10 and the Middle Road Highway (later known as the Queen Elizabeth Way) in 1937. In 1998, a 29 km section of Highway 10 from Snelgrove to Port Credit was downloaded. This section of Former Highway 10 is now known as Hurontario Street. The highway currently ends at the Brampton City Limits, immediately south of the new Highway 410 Interchange.

The Highway 410 Extension was completed between Mayfield Road and Highway 10 in November 2009. This new freeway diverts through traffic off of Highway 10 before it reaches the heavily-urbanized portions of Brampton. Highway 410 has provided much needed relief on congested suburban roads in Brampton and Caledon, which previously carried through traffic between Highway 410 and Highway 10. The completion of Highway 410 has resulted in the final 500 metres of Highway 10 being severed from the rest of the route. This small discontinuous section of Highway 10 is accessible via the Valleywood Boulevard interchange on Highway 410. However, this discontinuous section is just signed as "Hurontario Street" and is no longer marked as Highway 10.

The southern section of Highway 10 from Brampton to Orangeville is now a continuous four-lane undivided highway. The last two-lane section between Caledon Village and Highway 9 was widened to four lanes during a major reconstruction project carried out in 2008 and 2009. Highway 10 is a four-lane undivided highway from Orangeville northerly for about 10 km to Camilla and from Primrose to Shelburne. The remainder of the highway is two lanes, with some short undivided four-lane sections near towns. Passing lanes appear periodically along Highway 10 from Orangeville to Owen Sound. Services along Highway 10 are generally quite plentiful, except in some of the rural areas between Shelburne and Owen Sound, where services are somewhat scarce outside of communities. The speed limit on Highway 10 is 80 km/h (50 mph), unless posted otherwise. Please visit the Highway 10 Mileage Chart page for a list of mileage reference points along Highway 10.

Winter Driving Tip: The northern sections of Highway 10 are known for poor winter road conditions. The highway is sometimes closed during periods of poor winter weather between Shelburne and Owen Sound, due to blowing and drifting snow. Blowing snow will often result in zero-visibility conditions. The weather conditions on this highway can deteriorate very rapidly when snowsqualls blow in from nearby Lake Huron and Georgian Bay. On cold, windy days, it is a good idea to check the Road Closures and Winter Road Conditions pages on the Ministry of Transportation's Website, or verify road conditions by telephone at 1-800-268-4686 before using Highway 10 between Shelburne and Owen Sound.
