Completed I-494 Design-build Reconstruction project makes commutes faster and safer

Newly opened lanes of I-494 near Excelsior

This $137.5 million, award winning project started in August 2004 and was completed in September 2006 by Mn/DOT and its contractor Granite/McCrossan. The project added two new travel lanes, one in each direction and increased capacity of the roadway by 50 percent in each direction. The project also reduced the risk of crossover crashes through the installation of concrete median barriers.  Map
