The original Portal bridge was opened twice today (11/19) to prepare for the arrival. Both times it closed properly. It'll be intresting to see how it goes when the main span arrives.

I really hope the weather is great so we can see that whole maneuver getting the span up river of the swing span. Would not be surprised if the passage will be the heaviest ever transit thru the present bridge opening.

Dates for all the work for transiting and installing will need close attention to dates and times.

This span is one of 3 equal spans the other two can be seen in back of builder site.

This is the first of three tied-arch spans to be delivered from the fabricator located near Albany. Each of the three arches span 400 feet. To put things in scale, each arch is 86 feet high, 57 feet wide, and weighs about 2700 tons (5.4 million pounds). The channel width will expand from about 90 to 270 feet and clearance above the river will be 50 feet.

It is a huge advantage to be able to fabricate and assemble the arches off site then barge them to the work location rather than stick building the spans on site.
