The entire $12.6 million ($ in dollars) project was opened ceremoniously by Highway Minister James Snow on November25, 1977; Minister Snow was late to the ceremony due to a snowstorm. The old alignment was transferred to the St. Clair Parkway Commission between Sarnia and Sombra in 1979, and from Sombra to Dufferin Avenue (opposite Walpole Island) by 1982. The remaining along Dufferin Avenue to the new Highway40 was decommissioned between 1984 and 1986. Both Kent and Lambton counties designated their portion of the former highway as County Road33.
