As a lot will be happening at this gateway site, I have set up a separate blog site to follow the Arch: http://www.ottawachinatownroyalarch.blogspot.com/. It has a RSS button at the top of its page, so you can elect to have the new posts sent directly to you.
I anticipate there will be only one or two posts per week. At quiet times, there will be picture posts of arches in other world cities. I have found about 20 such pictures thus far.
You are unlikely to ever experience another royal arch construction in your lifetime, so be sure to pop over to Chinatown to inspect the progress, and follow the blog postings when you cannot be there. If you send me photos, I will try to use them: mailto:EricDarwin1@gmail%20(dot)%20com.
