Very much in keeping with Dallas' official “Live Large, Think Big” slogan comes a wonderful urban expression of the exuberance of this huge Texas city. The 400'-high Margaret Hunt Hill Bridge (MHH Bridge), designed by Santiago Calatrava, will span the Trinity River, connecting Dallas to West Dallas, and is expected to be complete in the spring of 2012, after 14 years of planning, design, budget cuts, redesign, and construction. The Trinity River Corridor Project, backed by a $245 million bond passed by Dallas voters in 2005, brought Calatrava to town to design three bridges over the Trinity River. Calatrava's bridges will provide an architectural signature for the Trinity River Corridor Project and hopefully will become a symbol of Dallas, nationally and internationally.

No matter where you live, you are bound to find a unique building material that is made close to home.

Generally speaking, I’m not much of a shopper. Like a lot of guys, I like to dodge into a store, make a quick purchase, and then skedaddle. Things change a little when I head to my local home center or hardware store. More than once I’ve come home from what was supposed to be a short jaunt to pick up some lumber to hear my wife ask, “What took you so long?” OK, maybe I was perusing the new LED lighting or trying out a new multi-tool. I was definitely NOT shopping.
