I-35W Bridge Beginning to Age

Seven years after the Minneapolis I-35W bridge collapse occurred, the replacement bridge is starting to age. Bridge inspectors recently found cracks in concrete girders, a clogged drainage hole, and rust above the bridge’s piers. The new I-35W bridge over the Mississippi River was built in 2008 after the after the old bridge fell into the river on August 1, 2007. The collapse killed 13 people and injured 145. Improperly designed gusset plates were ultimately determined to be the reason for the collapse. Federal regulators also discovered that the gusset plates were not given proper attention during inspections.

Minneapolis Green Line Nearly Complete

The 26.8-mile METRO Green Line project, connecting Minneapolis and St. Paul, Minnesota, is nearly complete.  Construction on the $957 million light-rail line started in 2010 and is now 98 percent finished.  The line will open for service on June 14th.  In the mean time, the Metropolitan Council will begin testing the new train cars and training 61 operators during the weekdays.   Siemens Industry Incorporated has already delivered over half of the line’s 47 cars.  The cars cost around $3.3 million each, with a total contract value of $153 million.  Siemens is also delivering 12 new cars for the Blue Line, the cities’ other light-rail line.  The Siemens LRVs will be the second generation of light-rail cars that the Metropolitan Council has purchased, and the cars will allow higher capacity trains to run at a greater frequency during rush hour.
