Innovation  
A monthly bike ride celebrating the virtues of cycling and demonstrating alternatives to automotive transport.
Description  

Critical Mass, described by its participants as an "unorganized coincidence," is a celebration of cycling and a form of direct action against "car culture." Its goals include creating safer streets, reducing air and noise pollution, reaping the health benefits of cycling, reducing transportation costs and promoting cycling as a fun and sustainable alternative to driving. Begun in San Francisco in 1992, there are now 400 regular Critical Mass bike rides in every continent but Antarctica. The first Boston Critical Mass ride occurred in July 1999. Today, Boston rides leave from Copley Square at 5:30 PM on the last Friday of every month.

Innovation  
Ten lanes of traffic cross the Charles River on the world's widest cable-stayed bridge.
Description  

With its graceful lines and 270-foot towers, the Leonard P. Zakim Bunker Hill Bridge fuses Boston's future with its historic past. In addition to being the widest cable-stayed bridge in the world, it is the first "hybrid" cable-stayed bridge in the United States. The bridge is a stunning addition to Boston's skyline and the capping achievement of the "Big Dig," the largest construction project in U.S. history.  Swiss bridge designer Christian Menn conceived the bridge design to reflect, with its inverted Y-shaped towers, the shape of the Bunker Hill Monument in neighboring Charlestown. 

  • 1,432 feet long, 183-foot-wide main span
  • Designed to carry 10 lanes of traffic
  • Replaced a deteriorating six-lane double-deck br
