Ok, I had a hunch it would be that way myself but all available sources to me didn’t have any such indication so I left it there from when I had mapped it previously and the latest imagery didn’t show anything under the bridge and according to that imagery it looked like that the connection to the ramp was going at that location. I still think that there will be a connection from the HEFT southbound to Dolphin easthbound ramp to this new ramp so that traffic can go from HEFT northbound to southbound directly. 

Happy mapping,
