King's Highway 406 - www.OntHighways.com

Highway 406 is a short commuter highway that runs along the west side of the Welland Canal, through Downtown St. Catharines, from Welland to the QEW.  Of note, Highway 406 is one of the three Ontario 400-series highways that is not fully a freeway -- the highway is two-lanes undivided south of Port Robinson Road in Thorold.

Road Info:  Highway 406 is generally in good condition for its entire length.  The southern portion of highway is currently a limited access highway, that at times can be quite congested.  There is an ongoing construction project that will see the freeway portion of the route extended southerly from Beaverdams Road to Port Robinson Road.  Through Downtown St. Catharines, because of some rather sharp curves, the highway has a posted speed limit of only 80km/h as opposed to the standard 100km/h limit seen on most freeways.  The rest of the freeway stretches of Highway 406 are posted at 100km/h while the two-lane portion is posted at 80km/h.
