             Ice jams and overflowing river basins forced the closing of several roads and bridges across the state  during the past week.  
            The Hwy 10 bridge over the  Mississippi River at the Little Falls bypass was closed March 17 due  to strong currents that caused an ice jam in the main channel and erosion to  the bridge. 
            District 3 crews monitored  the ice jam, which consisted of “massive ice chunks, six to 10 feet high in  some places,” according to Gary Dirlam, assistant district engineer for  maintenance operations. 
                          Repair work to the bridge began March 20  under an Emergency Order. Crews from Lunda Construction are in the  process of stabilizing the westbound lanes, removing the approach panels and  assessing damage to the bridge. 
               
              Dirlam expects the westbound lanes to be re-opened  by this weekend. The bridge will carry a single lane of Hwy 10 traffic in each  direction. Crews will then begin replacing the eastbound portion of the  bridge.  
               
  “Many people have been working very long  hours on this,” he said, noting that, ironically, District 3 had been preparing  to send crews to help in Moorhead or Montevideo before the Hwy 10 bridge  incident. 
   
  “It’s been an all-out effort,” he said.  
   
              While the waters appear to be receding  in some places, flood conditions continue to affect nearly half the counties in the state. 
            The Stillwater Lift bridge  over the St. Croix River closed March 23. The  lift span was raised seven feet and will be kept in this position until the  bridge is re-opened. Crews placed concrete barriers on the bridge to weigh it  down and protect it from floating debris. Metro District bridge crews will  monitor conditions around-the-clock. 
            Other Twin Cities roads affected by flooding  include Hwy  41, Hwy 101 and Interstate 35W in the southwest  metro area.  
            In St. Paul, one runway at the  downtown airport was closed March 24 and a taxiway is  expected to close March 25 to test the pavement for saturation. However, the  airport is not flooded  and is operational, according to Dan McDowell, Aeronautics public affairs  coordinator. The closures were expected to last less than 24 hours.  
            Strong winds  pushed chunks of ice from Lac Qui Parle Lake on to the westbound lane of Hwy 40  west of Milan, creating hazardous driving conditions March 23, said Diane Beck,  Willmar/District 8 public affairs coordinator. Plows were brought in to remove the  ice and by the next day the driving lanes were clear. 
               
               
            Along  the North Dakota border, in  the Red  River basin, segments of Hwy 1, Hwy 11, Hwy 75, Hwy 175, Hwy 220 and Hwy 317 are  closed, according to Karen Bedeau, Bemidji/District 2 public affairs  coordinator. In addition, the Sorlie Bridge on U.S. Hwy 2 business route in  East Grand Forks is closed.  
            In  the Detroit Lakes district, Hwy 12 east of Ortonville is closed between Hwy 75  and Big Stone County Road 21, reported Dana Hanson, District 4 public affairs  coordinator. Hwy 75 near Kent re-opened to traffic March 24 after being closed  for several days because of flooding. 
            Along  the Minnesota River basin, Mn/DOT and the State Patrol also closed several  roads, including segments of Hwy 14, Hwy 19, Hwy 93 and the Hwy 99 bridge in  St. Peter, according to Rebecca Arndt, Mankato/District 7 public affairs  coordinator.

            Rain, fast-melting  snow cause mudslides on Highway 8  
            By Beth  Petrowske 
            A mudslide just  south of Taylors Falls closed one lane of traffic on Hwy 8 from 6:15 p.m.  to 9:25 p.m., March 11. Flaggers directed motorists  through the open lane while maintenance crews removed debris from the road. 
            Concerned about  the possibility of another mudslide, crews monitored the area throughout the  night. As feared, a second mudslide occurred sometime around midnight. The area was  cordoned off early the next morning as crews worked to remove more mud, rocks and  fallen trees from the highway. 
            “It had rained for four days, plus the snow was melting so fast that  the hillside became extremely unstable — that’s what caused the mudslides,”  said Dave Hagle, Metro maintenance supervisor. “After removing all of the  debris from the road, we secured the bottom of the hill with riprap so it  wouldn’t slide any further.”  |
