This implies that the Department of Transportation doesn't have any motives for masking the problems with our infrastructure... Here is a photo of a bridge support for Northwest Highway I took a few years ago. I contacted the city engineer shortly after noticing that several columns exhibited this type of scour... I was told that they were aware of the problem and it was on the schedule to be repaired as funds become available.
This nations funding for our road infrastructure has been declining as a percentage of vehicle miles traveled on those roads (wear) since the 1970's/1980's and what funding that has been made has been getting split between the transportation road system and the transit system, leaving even less of the funding proportioned to the road system.
Do you feel comfortable driving over a bridge whose supports look like this?
So, despite Mr. Balmers' belief that government data is more reliable, I think the evidence is contrary to that at least in this specific case. I wonder how many others? Perhaps, all such sources should be examined with a critical eye?
