Here is the 401 on extremely-rare good days (traffic-wise)
!!!!
The King's Highway No. 401 (also known as the Macdonald-Cartier Freeway) is a freeway that extends across Southern Ontario, Canada. It is the longest 400-Series Highway in Ontario, the busiest highway in North America and among the busiest in the world. (wikipedia)
The 401 is widely considered to be North America's busiest highway, with an estimated Annual Average Daily Traffic (AADT) of over 425,000 in 2004, between the Weston Road and Highway 400 interchanges in Toronto. This surpasses the Santa Monica Freeway in Los Angeles, and several Interstate freeways in Houston, Texas. Due to its triple use as the main trade, commuting and recreational corridor in Ontario, 24-hour traffic volumes can exceed the 500,000 level on some days. The just-in-time inventory systems of the highly integrated auto industry in Michigan and Ontario have made the highway the busiest truck route in North America. Highway 401 also includes the continent's busiest multi-structure bridge at Hogg's Hollow in Toronto (four structures for the highway's four roadway beds).
Today the stretch of Highway 401 that passes through the Greater Toronto Area ranges from 6 to 18 lanes, and the stretch between Highway 403 and Brock Road in Pickering is thought to be the world's longest continuous stretch of highway having 10 or more lanes.
