The Indiana Department of Transportation (INDOT) announces that patching will begin Wednesday on U.S. 421 in LaPorte County ahead of a planned resurfacing project. Patching will be done in two phases. First, crews will patch the southern corridor of the project between I-94 and State Road 2. Then, when that work wraps up – up to two weeks, weather permitting – crews will move on to the northern portion, from I-94 to U.S. 20. Once all patching is done, the asphalt resurfacing will take place. For the patching work, flaggers will direct one lane of traffic around where work is taking place.
