Noticed two broken concurrencies in southern CA.
One is with CA111Pal and US99HisInd. The segment on CA111Pal between PalmSprLim and CA111Bus_S should be concurrent with US99HisInd. It may be as simple as adding adding a waypoint on US99His at PalmSprLim and removing the hidden shaping point there or changing the current hidden waypoint to a visible one (or something like that).
The other is with CA66 and US66HisAzu. Not sure which waypoint is causing the issue (PepAve at one end or MtVerAve/CA66_E at the other). Guessing one or the other is a NMP. Whatever the cause, the 2.29 mile segment should be concurrent.
