The latest Caltrans data that was given to "Toll Road News" (yes there is a journal dedicated to toll roads) is that there is an average of 1500 paying vehicles that use the express lane on commute days.
The improvements cost $195,000,000. This is $130,000 per paying vehicle. These vehicles will pay about $600 per car in toll fees each year. At this rate it will take 216 years to pay back the $130,000 that is owed by each paying express lane user.
Does it really make sense to spend this much money so a few executives from Lockheed can be at work 10 minutes earlier?
