My understanding is that heading east into downtown from the I-40/235 junction, the boulevard will not only have come down from grade by the time it reaches Stiles or so but must then be slightly below grade by the time it goes under the railroad tracks. This is to ensure 16’ plus clearances since the railroad will most likely have to stay at the same level. That does mean there will be no issue with clearances both for the streetcar itself plus its pantograph and the catenary (if that is the proplusion method). This will not so easily be the case for the rest of the bridges throughout downtown that were built as part of the 1930’s WPA embankment.

Much as I personally would like to see a line going straight east along Sheridan into Bricktown, everything I’ve seen for myself and am continuing to hear regarding the technical issues is making this less and less likely.
