Expanding Highway 400 at King Road

McGuinty Government Improving Ontario's Transportation Network

Ministry of Transportation

Ontario is widening a section of Highway 400 to make room for future High Occupancy Vehicle (HOV) lanes and rebuilding the King Road interchange. The project will ease congestion and improve safety on the entry and exit ramps.

Work on Highway 400 will take place in both directions from 1.1 kilometres south to 1.6 kilometres north of King Road. The commuter parking lot currently located in the southeast quadrant of the interchange will be moved to the northeast quadrant, with space reserved for a future GO Transit bus bay. 

The $35-million construction contract was awarded to Fermar Paving Limited of Rexdale. Construction will wrap up in 2010. Lane closures on Highway 400 are expected to cause minor delays. Drivers are reminded that speeding fines are doubled in construction zones.

Quick Facts

  • Everyday approximately 100,000 drivers use this section of Highway 400.
  • Since 2003, the McGuinty government has committed $9 billion to highways, roads, and bridges, and invested $7.4 billion in public transit.
