I used to drive 28 a couple years back to hit bigelow and it took me about 40 mins during the same 7:30ish timeframe, nowadays its like 1h20m to get to east Carson. All my issues stem from right after the RIDC exit, the highland park bridge, the double merge just past it (etna maybe? Idk where that is specifically), and the spot where it junctions into the veterans bridge (which was always a little congested anyway)
