Which Dangerous Street Intersections in the District 4 section of Austin, Texas, has Austin (TX) City Council Council Member Greg Casar Helped to Transform into Much Safer Places?

https://www.austintexas.gov/department/council-member-gregorio-casar-biography#:~:text=In%20his%20first%20term%20Casar,in%20their%20community%20including%20evictions "He (District 4 Representative and Austin City Council Member Greg Casar) has successfully advocated for the tens of millions of dollars necessary to fix Austin’s most dangerous intersections and corridors—many of those in District 4..." That statement comes directly from the official biography for Austin City Council Member Greg Casar that is provided at the official City of Austin website. Would someone please enlighten me about which of the previously-dangerous street intersections in Austin District 4 are now---thanks to Council Member Casar---safe intersections for motorists and pedestrians? It is great to sense that we have a heroic "Superman" representing us on the Austin City Council. For his next Herculean feat, could Council Member Casar possibly advocate to get increased lighting along our streets that might help to reduce our crime rate throughout District 4?
