The Minnesota Department of Transportation will carry out 75 road construction projects in the metro area this summer and a total of 221 statewide. Here are some of the larger metro-area projects where motorists can expect to encounter bottlenecks:

1. Interstate 35W in Bloomington: The bridge over the Minnesota River will be rebuilt and the freeway between 106th Street and Cliff Road will be raised out of the flood plain. The freeway will be reduced to two lanes in each direction.

2. Interstate 35W in Minneapolis: Fifty-year-old pavement and bridges between 42nd Street and Interstate 94 will be replaced, and the interchange of I-35W and I-94 will be rebuilt. Lane restrictions in both directions.

3. Interstate 35W in north metro: New MnPass lanes will be added between Roseville and Blaine, and bridges will be rebuilt between Hwy. 36 in Roseville and Lino Lakes. The freeway will be reduced to two lanes in both directions.

4. Interstate 35 in Forest Lake: MnDOT crews will build new bridges and replace pavement from the I-35E/I-35W split to Hwy. 8. Northbound I-35W will be a single lane approaching the split.

5. Interstate 35 from Harris to the Chisago/Pine County line: Repaving of 8 miles of the freeway. Single-lane traffic in each direction from May to September.

6. Interstate 94 in northwest metro: Work includes adding travel lanes from Hwy. 610 to Hwy. 101, rebuilding bridges and pavement rehabilitation from Maple Grove to Rogers. Expect off-peak lane closures, temporary ramp closures and narrow travel lanes.
