Width of N scale Kato truss bridge

Hey guys,
I’m designing my N scale layout based on a track plan published in MR and the plan calls for 2 kato single track truss bridges placed side by side. I need to know how wide the bridges are so I can space the track correctly. Also, is it possible to keep the track center spacing at 1¼” or are the bridges too wide for that? Thanks in advance for any help.

Anyone?

Kato bridge is 34mm or approx 1 1/4 inches wide. They do a double track version as well just for interest. Had to wait to get home to measure it so sorry for delay.
