Just a little FYI, the Portland Streetcar service south of Market St. will be interrupted from March 28th through March 30th 2008. They will be laying the tracks for the MAX line that runs along SW 6th Ave., which will intersect with the Streetcar track. Therefore the Streetcar will not run any further South during that weekend. However there will be shuttle buses that will service the streetcar line.
Here are a couple of fliers provided by Portland Streetcar to help you navigate during that particular weekend.
