Here's something for you bridge aficionados out there (including members of the WCLB). Massachusetts is on a bridge-building blitz, replacing 14 bridges this summer on a busy stretch of I-93 north of Boston. The schedule is truly ambitious, with each bridge slated to be demolished, rebuilt and opened for traffic within 55 hours.
According to this article at the Boston Globe, the project incorporates significant precast elements and includes penalties of up to $1.15 million per week for late delivery and a possible $7 million bonus for meeting all weekly deadlines.
Now we just need to find a way to replace this and this in 55 hours!
