King's Highway 402 -

Highway 402 is the main route between London and Sarnia.  Though most of Highway 402 is a fairly recent addition to the provincial highway network, the 402 was actually the third 400-series highway to be designated in Ontario.  Originally Highway 402 ran only through Sarnia, and had numerous at-grade intersections (including an at-grade rail crossing).  It was not until 1982 that the 402 was completely grade separated through Sarnia.  Coincidentally, Highway 402 was also officially opened in 1982, when the last stretch of new expressway was completed between Delaware and Strathroy.

King's Highway 402 Shield

  Western Terminus:  At the Customs facility for the Bluewater Bridge in Sarnia.

Eastern Terminus:  At the Highway 401 interchange south of London.

Length:  102.5 km.

Multiplexes:  9.3 km with Highway 21 near Reece's Corners.  Despite being obsolete, and no longer signed, this co-designation still legally exits.

Freeway:  Entire Length.

AADT (2002):  Highest: 25,600, from Indian Road easterly to Highway 40 in Sarnia;

                             Lowest:  15,700, from the Bluewater Bridge to the Bridge Street/Marina Drive interchange.

Road Info:  Most of Highway 402 is now in excellent shape, with one notable exception between Mandaumin Road and Highway 21-North.  The 402 has yet to be rehabilitated through this area.  On this short section, pavement conditions are poor, and lane widths are narrower then current freeway standard.  Also, motorists should use caution upon entering Sarnia from the east.  Because of some isolated lengthy backups on the Bluewater Bridge, the westbound Highway 402 speed limit drops to 80km/h west of Airport Road.  Police have actively been patrolling this section of highway, due to the abnormally low speed limit.
