A City of Many Bridges

Dallas has another moniker,the City of Bridges and I don't mean Maggie 1 and Maggie 2 only. There are some 5,000 bridges in the Dallas area according to one Tex Dot estimate. The High 5 added 43 alone. So that got me to thinking. With the work on the High 5 complete, the LBJ Express pretty much done and the I-35 length of 28 miles of re-work plus the Horseshoe Project of the Mix master. The cost totals estimated are from Tex Dots project pages.

Dallas High 5 at $288 Million
I-35E  length  $4.8 Billion
Horseshoe Project $798 Million

That is a combined total of $5.886 Billion of new updated Highways  and I could not find the published cost on the first wave of the LBJ Express Project. It was possible to find how the tolls would be priced, however and some very neat graphics of the total number of lanes and sub-lanes for the project.

Realizing that money comes from all kinds of avenues from Federal to State etc.,etc., the totals do come out about what the news media reported initially when announcing the projects. This isn't about cost anyway. That is an interesting sidebar to the fact that Texans should be proud that they are riding on some of the best and most up-to-day highways in the nation while other states are talking about the vast need to do what Texans have been busy doing the past 15 years.

Recalling that morning that I made the last exit on the old LBJ at U.S. 75 ramp. The big drilling machines were on the clover leaf  to drill the footings for the big green columns. They now make up the 710 columns of the Dallas High 5. Even today, I recall that old clover leaf going north on Central Expressway to westbound LBJ 635. That evening, the exit was closed and detours were rerouted and I can still locate where eventually the one big green column ended up being in that cloverleaf. I will post those in addition to this post since I can only post three images at a time.

Sunday, I drove the new I-30 bridge that now is the Margaret McDermott bridge with the north arch now in place for the very first time. The pictures that follow are from the High 5, the LBJ Express and the I-35E at LBJ 635 and the Horseshoe and the Maggie 2 bridge.
LBJ635 at I-35E

LBJ 635 between Dallas High 5 and I-35E. Officially known as the LBJ Express Project 
The Horseshoe Project which is a remake of the Mix master and new bridges and lanes over the Trinity with the Santiago Calatrava Signature Bridge 2 to be know as the Margaret McDermott Bridge. Also, for ease of ID of the two Margaret Bridges, the McDermott bridge is dubbed Maggie 2 while the Margaret Hunt Hill is known as the Maggie 1. Dubbed for two reasons. First, by chronology in construction and second by the number of arches,  which both co-inside perfectly.

It All Started in the wee hours of May 28th when 80 MPH winds was tossing everything against the side of my house.

 Those winds were substained for well over 40 minutes. The results were trees everywhere down or large branches broken off. One of my bus ro...
