How Columbia Island would have looked under 1990 proposal

Somehow I missed this map/proposal from the 1990 NPS Paved Trails Plan that I should have included earlier today. There are quite a few differences between today's reality.

1. A trail along the Boundary Channel from the LBJ Memorial to Washington Boulevard with an at-grade crossing of the GW Parkway southbound
2. The GW Parkway Crossing is farther south than it is now
3. There's a trail overpass over the GW Parkway to Washington Blvd ramp.
4. The Washington Blvd route under Memorial Bridge was to be removed and rerouted more on line with Washington Blvd on the south and to connect to Arlington Blvd in a different place on the north
5. The trail would go below the new Washington Blvd route through an underpass
6. Where Washington Boulevard meets Arlington Memorial Circle, the trail would go underneath through trail underpasses. 
7. A trail would go from the north side of Memorial Bridge to the MVT via a new at grade crossing of the GW Parkway near the north side of the island
8. Yet another at-grade crossing of the GW Parkway would be used to connect the trail to the Roosevelt Bridge's southside.

It would;ve been nice.

And the actual trail layout
