General Road and Highway Discussion

[GtwoK]

I noticed they've built the edge of the 85 bridge out another 3 feet or so - what advantage is gained by this?

That width was required to account for the new ramps needed for the new parts of the interchange. One small piece in a large puzzle.

That's what I had thought, but upon looking at this, the ramp there will require and entire other bridge to be built!
