Tunnel entrance

Hi, I've tried to map the retaining wall around a tunnel entrance as follows: The wall is mapped as a way with <barrier=retaining_wall> which crosses the node where the tunnel starts. To make sure that routers don't have any problem with this barrier, I've additionally tagged the node where the tunnel starts with <barrier=entrance>. Here's a link to an example where two tunnels start at one retaining wall: . Does anybody have comments or recommendations on this usage of the tag? --Biff (talk) 07:18, 8 June 2016 (UTC)
