Two elderly women in the right lane got confused with not being able to turn left at Girard toward Central due to construction and tried to turn at Richmond and hit the woman in a car passing them in the left lane. Both cars were so badly damaged (both with front wheel drive axels broken) they could not move. I heard it and came out to direct traffic around the crash site. I had several drivers cut around me and wiggle through the crash site and one man got out and tried to start a fist fight. Cutting through this site like that is dangerous and likely to cause more accidents or hit one of the vehicle passengers. It took a long time for APD to respond because no one was injured seriously but the vehicles were disabled blocking Coal which was causing a larger problem as drivers screamed intolerantly for us to move the vehicles, open the road. One huge tow truck with a crashed car on the back zig-zagged right through almost hitting folks again. I am lucky this time the as car on the left did not come through my yard wall and get near the house, which has happened several times in the past. I just rebuilt the wall this spring from another crash like this one. This roadway is dangerous, over loaded and complicated by ART. But our city planners, the council and mayor think we are in a great leap forward. Zuni to downtown at 5th are atrocious for moving people around the city safely. Glad I am not a bicyclist in this new planning craziness. Add to this all the outright drag racing and loud show off driving on Coal and one can see why business leaving downtown (see Journal this morning) are not going to relocate to the Nob Hill area… Our city is changing rapidly from a once nice place to live into one with no solutions in sight for collective structural improvement (most of the politicians are giving up too and getting out or moving on to other offices it seems).
