Yes, that's one of the worst choke points in downtown. It makes the capacity of the 670 viaduct totally worthless.
You fix that by first not allowing the west loop access to EB 670. (or WB 670 access to the west loop) and also rebuilding the bridges to allow space for more lanes under the big interchange.
Then you have two lanes of NB 35 and 2 lanes of EB 670 come together with four lanes under bartle. It used to be four EB lanes, but they removed a lane with markings. They need to stripe 670 back to 4 lanes each way.
Then you would have two lanes split off to EB 70 and two lanes split off to NB 29/35.
You already have a lane that adds and drops to SB 71.
Widen the east loop to 4 lanes each way from the SE corner of loop to Bond bridge and remove most of the exit ramps. Build one big high capacity exit for downtown in that area.
