The confusion about type probably comes from the fact that modern pedestrian bridge companies typically call anything with a curved top chord a "bowstring."

I agree with Royce, the design description was taken right from the magazine article, which was obviously written by someone without a knowledge of truss types. This is a 3-span continuous Warren truss; the outer spans have horizontal upper chords and the center span has a curved one. This is certainly not a bowstring truss, mainly because the curved upper chord does not connect to the lower chord at the piers. Also, the Warren configuration does not fit with the bowstring definition. In my opinion, it's much nicer looking than your typical MOB, as it's made of laminated wood rather than weathered steel. This community already is joined at the west end by a preserved historic truss bridge.

Is it me? This doesn't look like a bowstring truss to me.

But this one is made of wood

I would have added it if I could

My previous comment was wrong

This bridge does truly belong

A MOB of such great size

Will make you shield your eyes

Our bodies have such great reflexes

Not everything's bigger in Texas
