It now costs more to take the Detroit-Windsor Tunnel from Canada to the United States, but traveling from the US to Canada costs the same.
The new fare, which took effect Saturday, is now three dollars and 50 cents (in US dollars) and four dollars (in Canadian dollars).
The cash fare from Detroit to Windsor is still three dollars and 50 cent (in US dollars) and four dollars and 75 cent (in Canadian dollars).
A spokeswoman with the Detroit-Windsor Tunnel says the increase is a result of Windsor replacing and modernizing project that will cost about 14 million dollars.
The last toll increase was in 2001.
Commuters on both sides of the border also are paying more for prepaid tokens and coupons.
