An interchange in the Dallas area

Maybe you're getting tired of Venture Out pictures... here's a post I wrote (but didn't post) when we were in the Dallas area.

I do most of the driving when we are in the DFW area because I know the roads better there (Carl does most of the driving when we're in the Chicago-land area for the same reason). Carl particularly does not like the high overpasses at some of the freeway interchanges...

High 5 interchange at I-635 and 75 north of Dallas -- up to 12 stories high! (from: By austrini - https://www.flickr.com/photos/fatguyinalittlecoat/2909850055/, CC BY 2.0, https://commons.wikimedia.org/w/index.php?curid=10298513)

I pulled some information about this interchange on Wikipedia (https://en.wikipedia.org/wiki/High_Five_Interchange):

  •  "The interchange is as high as a 12-story building, and includes 43 bridges spread across five levels (the "High Five"), 710 support tiers, and 60 miles of additional highway. The highest ramps are 100 feet (30 m) above ground. The lanes of US 75, which are on the bottom level, are 20 feet (6 m) below ground level, giving the structure a total height of 120 feet from bottom to top."
  • "The construction contract for the High Five Interchange was unique in that it contained elements not found in other construction project contracts. ... For example, ... built into the construction contract was a provision that [the construction company] be charged for "lane rentals" by TxDOT for time they closed down traffic lanes—fees based on hourly assessments and the time of day the lane was closed. The fees ranged from $50 to a high of $110,000 for rush hours."

From living in the Dallas area, it was definitely an area to avoid in ice storms / freezing rain!
