either ride the sidewalk (what i do everyday, two way traffic is common and there is enough room for two bikes side by side).
or take a right at the green lane bridge and then make your first left. that road will also take you to he same spot.
the second option seems to be favored by roadies as the sidewalk is a little rough in spots but nothing a bike can't handle.

related topic #2: if you didn't know, they cloes mlk blvd (the road on the otherside of the river) to vehicles on weekends in the summer.
