Street View 


The first bridge at this crossings appears to be a three span lenticular truss or possibly a bowstring truss. It is there in a picture from 1883 and has been replaced in a picture in 1899. The second bridge at this crossing is a three span Iron through truss. Earliest appearance I could find in pictures is 1899. Lengths are estimated.

Oh,apologies - It was unclear to me that the listing is for the second bridge in the photographed grouping.

This is a duplicate listing - And I do not know this bridge to have ever been known as the Steam Bridge.

See The McGregor for more photos and background. information.
