According to an article in the Seattle Times the Feds [are] OK with I-90 tolls to help pay for new 520 bridge. What's even more interesting is the last statement, "The federal letter said excess toll money could be used to pay for transit, if it's used for the Lake Washington corridor."
Apparently the Feds are all about giving out cash to implement electronic tolling and using variable fares to manage traffic. So, even though the SR520 bridge project is no where near shovel ready the State can bring home a nice slab of pork if they start tolling now rather than after construction as has always been the case in Washington.
So, my question is why not expand this to convert the I-5 Express Lanes (an oxymoron if you ever look at the traffic reports during rush hour). More money for more buses that could actual operate at the speed limit funded by drivers that choose to use the Lexus Lanes. The fat cats using the Lexus Lanes get to work faster and probably write it all off on their federal income tax anyway, right? A win win for everybody. Go HOT Expresso Lanes!
