A visit to the neighborhoods of Minneapolis provided an opportunity to review some of the infrastructure that is common in big cities. There has been a lot of chatter about the Highway Trust Fund running out of money and the need for a reinvestment in our infrastructure. I agree with that knowing what I know about how our signals are falling apart because they are over 50 years old. Here's a few examples where infrastructure reinvestment in Minneapolis would reduce the likelihood of failure.
|Normally with a mast arm traffic signal pole, |
there aren't wires aerially throughout the intersection.
It's likely the underground conduit has failed and
the overhead wiring is a substitute.
|This sort of wiring is not standard. I am hopeful that there aren't more examples like this.|
|A combination traffic cabinet and signal pole. |
Portland has none of these, so this must date back 50+ years.
|This may be the longest linear pothole/crack that adds separation between the bike lane and the motor vehicle travel lane|
