520 has been pretty empty this week and last. I *think* I read some where that DOT estimated 10% or maybe 20% of traffic would stay off roads or use I90.... My morning and evening commutes have been as short as possible.

Seems like more motorists are avoiding 520 than previously thought. Just like Salmo G's post, a lower toll = more motorists, the standard price versus consumer willingness to pay curve we all learned in Econ....Seems like it may take longer to get this project paid off than previously thought if the road continues to be pretty empty...I sure know if tolls were only a buck or two I wouldn't care but for $3.50 (I have a pass) I think twice about crossing it...
