For anything South Dallas or the Grove, you need to follow Smash Da Topic on facebook. Everyone calls the dude Smash. There's two videos of the wreck there and probably 1200 comments, but no written story and I don't have the time or inclination to go through it all.
I know this is going to sound racist, but I drive that stretch of road nearly every day. I have two business locations and that's the most direct route between them. To put it simply, it's a culture problem, no one gives a fuck about South Dallas, and it's just as much the people who work in city hall as it is the people who live here. I think I've been here long enough to stop caring too.
The next morning after that wreck, there was another wreck half a mile down the road at Pemberton Hill, hit hard enough to overturn another car.
Some asshole with money thought it would be a good idea to put a red light there at the new golf course so we could all wait on their ass, there was a fucking 3 - 4 car wreck a few days prior to this one. Red light? That's just a fucking suggestion.
Racing all the time, driving 3 wide on the shoulder all the time. Running red lights is normal. Paper tags is normal, speeding is normal. Cars running off the road and taking out guard rails is normal. You could make the speed limit 20 mph with speed bumps every 100 yards and people would still get killed.
I think it was about 2 years ago, some security guard got wrapped up in a race at Loop 12 and 310, he got smushed. Died in his car, some goofball filmed it and posted it online. Go back 3 or 4 years ago, former city council woman Carolyn Davis was killed by a white dude driving drunk a little further down the road. Guy was a multiple dwi offender and still out cruising South Dallas drunk as a skunk driving the wrong way down Loop 12.
But hey, she was awaiting federal prison sentencing for taking brides. At least we didn't have to pay for that. Someone gets convicted of that stuff about every other year, pretty sure it's the norm in government around here.
Your safest bet to turn off at Elam and cut over to Jim Miller and avoid that whole section of road if you need to go that way.
