You do not need to check if it is open. Hyperlink to it. If it is already
opened you will jump to it, otherwise it will be opened:

Sub anothre()
Dim s As String
s = "S:\_TRACKERS\NJ Daily Totals\CM Update Trackers\FCCONSTRUCTION
TRACKER_V2.xls"
ActiveWorkbook.FollowHyperlink Address:=s
Sheets("FC Construction").Select
End Sub
