Another thought...
Once CSVT is complete, is there any reason for PA 61 to continue across the Susquehanna River via the Veterans Memorial Bridge? It would be concurrent with PA 147 on the bridge and new connector before arbitrarily terminating at US 15, while PA 147 would continue north concurrent with 15. Seems just as effective for PA 61 to terminate at 147 east of the river, leaving 147 as the sole designation on the bridge and connector. This would greatly simplify the signage on the bridge approaches and junctions with the new connector.
