Stopped by the Metro garage last night and chatted with a PL worker. The crane is a Manitowoc 450 ton model. Just getting it there in pieces required ~7 special permitted shipments. It's sitting atop a WSSC watermain that has many people nervous. It has a ballast that extends out automagically as required by the loading
They have bridged the Red Line with 2 of the 4 girders needed. (Seen in my previous post.) They must be installed in the right order to ensure they can be placed correctly. While the Red Line is shut, CSX is single-tracking on their SW track; a CSX employee was there to coordinate the movements. Manitowoc had several cameras on and around the crane over the weekend; maybe they'll release the bits at some point.
They will be taking a break of two weekends before bridging Colesville Rd; I'm not sure if they'll be installing the steel east of Colesville towards Bonifont in the interim but I doubt they'd leave an a$$et like the Manitowoc idle for more than a lunch break.
