So my take on this is that the whole thing should be looked at more in context. I did the access to the little residential across from the Mint to be a sort of combined diamond with Fermor. The Patterson access is closed completely as is Cottonwood. I maintain the crossing over Lag at Cottonwood so that it's still possible to go back and forth - and in retrospect probably can leave the
Patterson to Springs crossing too, just no access to Lag itself. The plan would also require some substantial upgrades to the surrounding smaller roads to help with access from certain properties, but all in all, shouldn't require a huge amount of property acquisition.
My plan would have Lag dug down several meters and have MSE walls and embankments to allow for the steep slopes required for the road to be that low. The idea would be that all the crossings would not require building up and be essentially at grade.
