The DOT has redesigned its public-meetings page so that the project documents are now an additional page-click away. The text on the sub-pages is shown as a continuous string, with no breaks, which can make it difficult to read.
So to see the documentation and map for the plans for US 63 in central Waterloo, for example, you have to click to here.
The map available there (PDF) shows how 63 on Logan Avenue will change from being straight to slightly slanted, sitting on the northbound lanes and east houses south of the railroad and the southbound lanes and west houses north of it. The right-of-way comes right up to Logan Middle School’s front door, but that doesn’t matter because the school is going to be demolished.
A complete rebuild of US 63 between Hudson and US 20 is also planned. However, those maps haven’t been released. I think it should be upgraded to four lanes, but the press release says nothing to that effect.
