Reply to "Size for Standard gauge tunnel portal, using Hellsgate bridge"

A modicum of searching reveals this information copied from here:
The "original" 300 Hellgate Bridge is 28-1/2" long overall, 10-3/4" wide, and 11-1/2" high. The clearances of the bridge opening are 5-7/8" wide and 7-1/2" high at the center point of the arch (7" above tubular track rail).

The re-issue 305 Hellgate bridge is 30" long overall, 12" wide, and 11-1/8" high. The clearances of the opening are 7" wide and 7-1/2" high at the arch center point - still 7" above the track rails.

NB: emphasis added for clarity.
