The doc posted is announcing an RFP to study a "grade separated" crossing. (Grade separated means either a bridge or a tunnel.)
This just means a study might happen at some point in the future. This doesn't mean that construction of a crossing will be starting anytime soon.
Any sort of major construction around the 78 & the UP tracks would draw out all of the enviro wack jobs to oppose the necessary ground disturbance.
I am hopeful that this means that "someday" we might be able to access the trails on the East side of the tracks and Boardmanville. But the odds of it happening in less than 10 years are pretty slim.
I don't mean to be a Debbie Downer on this but at least it's a first step showing that our voices are being heard about access issues like this one.
