    Info on the train bridge collapse in Arizona

    You've all no doubt heard about the freight train derailing in AZ, collapsing the bridge into Tempe Town Lake. I cross the Valley Metro Light Rail bridge right next to it, every time I travel from the "East Valley" into Phoenix. That bridge was built in 1912, and is (or was) essentially supported by old style telephone poles, made of wood and treated with tar as a preservative. Highly flammable to say the least.

    In the late 70s, the remnants of a hurricane blew threw the area. A deluge of water had to be released from Roosevelt dam to the east, washing out every bridge from the East Valley to Phoenix. The 2 only bridges left standing over the Salt River (Rio Salado) were that freight rail bridge, and the Mill Avenue Bridge about a quarter mile east of that bridge. A traffic nightmare to be sure.

    To get to work today, I had to get off the train mid way through the journey, and hop a bus to a rail station on the other side of the fire...all in 115 degree heat. I arrived at work a half hour late, and home a full hour. The bridge will have to remain closed not just until the tanker car holding highly flammable chemicals is righted, but until every car is removed from what's left of the bridge. They can't very well have a passenger train running immediately parallel to a line of freight cars, in danger of collapsing into the lake. Getting to work the next few weeks should be loads of fun.

    I lived there in the 90s and crossed the Mill Ave bridge on the way to my guitar lessons in Tempe. The riverbed was dry back then... Looks like they really built up along the shore since then and made it a touristy spot.

    I believe the correct response here is: Holy crap.

    The "lake" was created by constructing 2 dams on either end. You might think it logical to fill the lake with Salt River water from Roosevelt Lake, but that's not the case. The farmers upstream own the rights to that water, because they largely funded the construction of Roosevelt Dam in the early 20th century. The lake was filled, and is refilled by Central Arizona Project water from the Colorado River. The only time Salt River water finds its way to Town Lake is when Roosevelt Lake gets too full, and water must be released.

    BTW: You'd find the drive from Phoenix to Tempe far more convenient today. There's now the 202 Papago/Red Mountain Freeway running parallel to Town Lake and Salt river. There's also the 101 Pima/Price Freeway running from North Scottsdale to South Chandler. You may or may not remember in the early 90s, the 101 was exactly 2 miles between University and Southern.
