Construction in Bethesda - Tower Cranes

There is a lot of construction going on in Bethesda, Maryland.  Eventually it will result in a lot of jobs and housing within walking distance of the Purple Line and Red Line stations.  In the meantime, the sidewalk closings are a major inconvenience for pedestrians, often requiring pedestrians to cross major streets multiple times to get to their destination.

For those who are curious, this is what the foundation for a tower crane looks like.  The four mounting points are set in several feet of concrete.

And here is the process of the tower cranes being erected at the site of the new Marriott International Headquarters Building.
