MnDoT has announced lane closures that will affect drivers traveling on Interstate 94 between Monticello and Hasty.  Beginning tonight at 8:00 p.m. eastbound lanes of I-94 will be temporarily closed. At about 11 p.m. crews will move to the westbound lanes.  MnDoT says the lanes are being closed so that crews can replace overhead signs on the freeway.  Officials are asking drivers to slow down and watch for workers on the roadways.
