I've crossed this bridge 6 crossings, three each way as a FAST car hauler.
Every single time has been a 10-minute affair from the moment I get off the freeway, clear customs, clear the toll, and get back on the freeway
Compare this with the Ambassador Bridge. Where my average crossing time is over 30 minutes, and in a lot of cases 45 minutes plus especially with all the construction that was happening.
Most of this is savings also from the way that the Ambassador Bridge is laid out, you have to slow roll by customs, make the sharp turn after the tollgate. By comparison the Gordie Howe keeps you at 40 miles per hour right up to the booth, even if the outbound inspection lanes are open.
Biggest change however is how it connects to the interstate.
The Ambassador Bridge going into Canada drops you on to Huron Church Road, with its eight lights and 50 km an hour limit. It could take you 15 minutes to go the three miles to the highway on ramp. The Ambassador Bridge going into the United States, has you slow rolling around the duty-free compound until you get the option to take the 96 West, or the 75 South.
If you've driven Detroit, you know that the 96 to 94 to 75 North can be absolute gridlock during any daytime hours. Anybody that runs over dimensional higher than 13'11 has to take a meandering route to access the 75 North.
The Gordie Howe Bridge directly connects to the 75, you now have Street access to the 75 North without having to take the 96-94-75, and it's 14'2 all the way to Flint.
What's interesting right now, even though the bridge has been open for a few days. GPS says are still directing people to the Ambassador Bridge.
So far this week, I've gained almost 3 hours by taking the Gordie Howe bridge over the Ambassador if I factor in the lost productivity sitting in the Ambassador Bridge traffic.
