Air carrier Captain reported the repainted Taxiway Y1 at BNA visually reduced the wingtip clearance with outbound traffic on Taxiway Y2. Reporter also stated the charts incorrectly depict Taxiway Y1's change of position after the repainting.

Narrative

BNA Taxiway Y1 has been repainted and shifts to the left abeam Spot 25 resulting in perceived lack of wingtip tip clearance with outbound traffic on Taxiway Y2. BNA Ramp Control cleared us to Gate D1 via Y1 with no concern for outbound traffic on Y2. The BNA 10-9 page; both Chart and AMM (Airport Moving Map); and BNA company information page incorrectly depicted the change to Taxiway Y1. The GPS tracking on the 10-9 showed us well left of the original Y1 taxiway. We held right of the new line abeam Spot 25 to ensure a safe passage. After reaching the gate; I reached out to a BNA ground operations supervisor to voice my concern and also spoke with the chief pilot. I spoke with the BNA Ramp; they believed the current taxiway configuration ensures 20 ft. wingtip for which it appears to be otherwise. It warrants another look by BNA personnel to ensure the new taxiway configuration ensures proper wingtip clearance.Suggestions: Under the current taxiway configuration; air crew should be cautious for conflict near Spot 25. Additionally; the current taxiway configuration abeam the terminal near Spot 25 needs to be reevaluated to ensure proper wingtip clearance for all aircraft.
