Problems with Burn Stream slope and DEM Reconditioning

I'm trying to delineate watersheds for a project using ArcHydro 10.1 beta.

Both the Burn Stream Slope and DEM Reconditioning run successfully, but the resulting DEM has hardly changed.  The stream I'm dealing with runs under a bridge and so when I run through the whole process the drainage lines end up running along the road instead of actually following the stream path. But I need to have the stream burned into the DEM so that it follows the correct path.  Unfortunately I'm not seeing that happen.  I've tried increasing the Buffer for the DEM Reconditioning and increasing the drop rates, but nothing seems to be making a difference.

I'm using NHDFlowline for my stream and a 1m DEM.

I'd really appreciate if anyone has any ideas on how I can get the stream burned into my DEM.
