King's Highway 3 -

Before several sections of Highway 3 were downloaded, the Highway 3 designation extended from Sandwich Street at the Ambassador Bridge in Windsor easterly to the QEW at the Peace Bridge in Fort Erie.  This is notable, as no other Ontario highway has had the distinction to have both of its termini at international crossings.  In 1997 and 1998 several sections of Highway 3 were decommissioned leaving three discrete sections of provincially maintained highway today.  These sections now run from Sandwich Street in Windsor easterly to Highway 77 at Leamington; from Highway 4 at Talbotville to Townline Road just west of Port Colborne; and from Highway 140 to Rose Hill Road just west of Fort Erie.  The decommissioned portions of Highway 3 have since been designated by the counties that now maintain the route.  From west to east, the county roads that fill in the discontinuous segments of Highway 3 are: Essex Road 33, Essex Road 34, Chatham-Kent Road 3, Elgin Road 3, and Niagara Road 3.

Old Style King's Highway 3 Shield

  Western Terminus:  At Sandwich Street in downtown Windsor

Eastern Terminus:  Pre-1997:  At the QEW interchange in Fort Erie.

                                      Current: Rose Hill Road just to the west of Fort Erie


Discontinuity (since 1998):  Highway 3 is now discontinuous in two places.  Most notably, all of Highway 3 was downloaded between Highway 77 at Leamington to Highway 4 at Talbotville.  Highway 3 is also discontinuous in Port Colborne as the connecting link has been repealed by the MTO.  Fortunately within Port Colborne there are sporadic signs directing through traffic through the discontinuity.

Length:  Pre-1997: 411.0km.  Current: 115.7 km.

Multiplexes:  None

Freeway:  Highway 3 is a super-2 expressway through St. Thomas

AADT (2002):  Highest:  29,100, from Howard Avenue easterly to Highway 401 in Windsor;

                             Lowest:  2,750, from First Avenue easterly to Centennial Street on the St Thomas Expressway.

Road info:  Highway 3 is generally in fairly good condition.  The western segment of the route is in excellent condition but is quite congested.  The central and longest segment has the most variance in condition but is in for the most part, good or fair shape.  The eastern segment is once again all in good condition.  The downloaded portion between Leamington and St. Thomas is at times fairly rough, but is for the most part quite lightly traveled.  Highway 3 has a rural posted speed limit of 80km/h.
