The latter being mostly the case down here in Mississippi. Lately, it seems MDOT has been more interested in pushing its projects through rather than let the public know what's going on with them. Just today, the SunHerald ran an article about proposed improvements to MS 57 between I-10 and Vancleve that are a few years off, including mentioning that the Feds have signed off on the environmental assessment and that there's a preferred alternative. And this is one of the better cases, in that at least there was a section about the project on the MDOT website, even though the announcement about the public meetings that were held this summer wasn't posted on their website until well after the meetings were held.
And that's to say nothing about there being no MDOT news releases posted since New Year's, and getting to the news releases from last year is impossible due to some website glitches.
They could do a lot to learn how posting project information online can help the public input process...something MDOT has been sorely lacking in for a long time, not just with recent events.
