I haven't driven across (or wasted hours trying to) the GW in more than 25 years, and I didn't know that the tolls had gotten that high. So a reasonable question to ask might be, "where is all that money going?" Construction on the bridge began in October 1927. Surely, it must be paid off by now.
The ongoing project to replace the entire upper level roadway decking -- which began in 2012 and is supposed to be completed next year -- cost $82 million by itself.
The next major project to be undertaking on the bridge will involve the rehabilitation of the cable support system and the replacement of all the suspender cables (there are about 600 of them). The price tag on that project is approximately $1 billion.
You don't just build a bridge and walk away from it. It costs a fortune to keep it in good working order when it's more than 80 years old.
